1. Are air conditioning costs affected by the heat index?

No, your AC always works at the same speed, it just turns off and on to keep the temperature to what you set on the thermostat. .

2. Can birds be in air conditioning?

It depends on what kind of bird you get, but most birds can get sick if there is a cold draft on them

3. Is it cheaper to run my gas fireplace or my heat air conditioning?

Well for that square footage we can figure you will need a a 30,000 BTU fireplace. Assuming this is the case, you will burn about 1 gallon of LP per 3 hours. Current US Residential Propane Price is at a current level of 1. 98USD/gallon. So we average your 6-12 hours at 9, and I think you will be burning 5.94USD a day as of today. Of course propane prices fluctuate significantly so that could double pretty quickly.I have herd of newer 3 ton heat pumps that run at 2. 5 to 3. 0 kw even at 30 degrees F, which you experience in Colorado. That is without auxiliary kicking in. I think for your square footage in your region you would probably be told you need a 2 ton minimum, but I am hoping you did not go with the minimum in your environment. Colorado has a 11.2 kw/hr rate as of today. So at worst case I would say your spending around 33. 6 cent an hour, 3. 02USD a day. Propane often has more peripheral cost for maintenance and service than electrical systems do. I say, for cost use a heat pump. For the odd romantic evening between you and your special someone... maybe with some Jack Daniels and a Kurt Russel film? Then fire up the fireplace!Is it cheaper to run my gas fireplace or my heat air conditioning?.

5. The Ultimate Guide To Air Conditioning This Summer

Although it happens every year, there's something magical about the beginning of summer; the trees are green and full, the sun sticks around later each night, the flowers are fragrant, and everyone seems a little bit happier. And with summer arriving, some preparation needs to be done: cleaning off the BBQ and filling the gas bottle, buying new togs, and investing in air conditioning to make sure you survive the hot, sticky months ahead. If you are considering what an air conditioner could do for you and your family this summer, you are in the right place. With more and more homes embracing air conditioning NZ-wide, we've compiled the ultimate guide to air con in New Zealand. Let's dive in! Are Air Conditioners and Heat Pumps the Same Thing? If you are weighing up a decision about whether you should install a heat pump or air conditioner, we've got great news: A heat pump is an air conditioner. The only difference is the cycle you select when using your unit. When using the unit as a heat pump, it works to bring in the warm air from outdoors (yes, even in winter there's heat energy in the air outside) and pump it around your home. A heat pump is a very efficient way to heat your house and it does so quickly and quietly. We've got a great blog on tips when using a heat pump - have a read! When the unit is used in cooling mode, the cycle reverses. Now, instead of pulling in heat energy from outside, the unit takes the heat energy from inside your home and transfers it to the outside unit where it is cooled. Finally, it's pumped back into your house as cool, refreshing air. Basically a heat pump is a fantastic two-for-one deal. Not only do you get a best friend in winter, warming your home on demand, but you also get a summer saviour, keeping your home cool and welcoming on even the hottest days. Ways to Keep Your Home Cool This Summer Summers in New Zealand can be long and hot, and sometimes it can feel hard to get a reprieve from the relentless heat. If you are dreading the warmer temperatures this summer, you will need a battle plan to stay as cool as possible. Luckily there are a few different tactics you can try to keep conditions cool and calm. The easiest way to keep your home comfortable is with passive cooling. This is a simple and cost-efficient way to help keep your home's internal temperature low. Many newer homes are designed with passive cooling specifically in mind, but even in older homes, you can do things such as creating a cross-draughts by opening doors and windows. If your windows are not fitted with security latches, consider installing them so you can continue to cool your home as you sleep without concerns about security. While we all love a home that gets a lot of sun, sometimes too much will have the interior of your house feeling like a sauna. Instead, try closing the curtains or blinds of the windows that receive direct sunlight. Similarly to closing your curtains in winter to keep the cold out, doing this during summer will help stop your home heating up to uncomfortable levels. You could also consider external window shades as an option. Installing blinds, awnings or louvres means you keep rooms shaded during summer, but can still let the light and heat in when you want. While curtains and blinds are trying to keep heat out of your rooms once its already entered your home, external shades prevent the heat from making its way inside at all. Is your home well insulated? If not, do not worry - thousands of New Zealand homes are not . But having a sufficiently insulated home wo not just keep your house warmer in winter, it will keep it cool during summer as well. This is due to insulation being a thermal barrier, preventing the transfer of heat. Insulating your home can be done in stages, with the ceilings being the smartest area to tackle first, followed by your floors and then the walls. Because the insulation is working to prevent heat transfer, a well-insulated home will not only be more efficient to heat but also more efficient to cool. This saves time and money in the long run. Sometimes in hot weather, all you really want is a constant breeze blowing and with fans being cheap and accessible, this is an easy solution for summer. Fans can really help with stirring up and circulating heat - especially great for rooms that see a lot of sun, or where lots of people congregate. Fans wo not cool down the air, so in really hot conditions it will only be blowing warm air. However, you can create temporary cold breezes by placing bowls of ice or a wet cloth in front of the fan if things get to scorching levels. A long-term solution to keeping your home cool is having an air conditioner - a.k.a a heat pump - installed in your home. Air conditioning NZ homes are a great way to keep you comfortable in summer, and there are a number of settings and models that mean you can find the best solution for your home. The cooling setting on an air conditioner will help significantly cool your home down, this is great for those stifling days and works best when all doors and windows are shut - much like the aircon in your car. And, depending on what system your home is installed with, you could cool multiple rooms of your home at once. You can also make use of the fan setting on mild days, keeping the windows open and using the air conditioning unit to create a refreshing breeze. Whether it's a large or small air conditioner, having a unit installed in your home is a great idea for summer - and it comes with numerous benefits. For those days when the weather is forecast to reach high temperatures, use your aircon's timer function and set it to turn on before you get home from work. This way your home will be a cool oasis from the moment you walk in the door. Using an air conditioner during summer also helps you get a cool night's sleep. And it means you do not need to leave windows open and risk being disturbed by noise and bugs. Depending on the system you choose to install, you can use your air conditioner to quickly cool down a single room - such as your main living area - by closing doors and windows. Alternatively, you could opt for ducted air conditioning. Auckland, Northland and other areas in the upper North Island frequently suffer through hot and humid conditions. Ducted air conditioning means that multiple rooms are able to be cooled through a unit that sits in your home's roof space and pumps cool air into the house via pipes. Using a Panasonic air conditioner in NZ homes is a great choice and each Panasonic unit purchased through HRV comes with a 5 year warranty. That way you can rest easy knowing your investment is protected. Of course, one of the best benefits of having air conditioning in NZ is that in winter it doubles as a heat pump. Forget freezing, frosty mornings and hot, humid afternoons with your heat pump and air conditioner in one. Now that's a multi-purpose appliance that's handy year-round We know that Kiwi families have all kinds of needs, which is why HRV has multiple types of air conditioners for all kinds of homes. A High-Wall air conditioning unit is perfect for a single room. The unit is mounted on the wall that you want to cool and connected to an outdoor unit via ducting. Because the unit is mounted close to the ceiling, it's unobtrusive on your space and quietly works to cool (or heat) as you get on with life. If you would prefer to heat and cool multiple rooms of your home, a Multi-Split air conditioning solution might work for you. This system still has one outdoor unit, but it connects to multiple indoor wall-mounted units. This way you can ensure you will stay cool in many different rooms, including your living room and bedrooms. A ducted air conditioning unit is another good option if you want to cool more of your home. This system hides the main unit in the ceiling cavity of your house and uses ceiling vents to push cool air into each room. With ducted air conditioning, you do not have any visible units mounted on walls or outdoors, only small vents in the ceiling.

If i use the air conditioning in my car will it use some of the gas or will it use the battery power?The ac unit is driven by belts and compressors. There is some toll taking on fuel economy because your engine works a little harder to turn the compressor. Its really boils down to what comfort level you can live with. Since your altenator recharges the electrical system there is really no draw on the battery.... d4.

How do you fix poor home air conditioning circulation?Close the vent in the basement to have more air pushed to the other parts of the home8. How much should air conditioning repair cost?You got off very cheap. As far as a 400% mark up on a capacitor, you did not pay for the capacitor, you paid for the techs knowledge and the fact that he was able to diagnose the problem. You paid for the fuel and wear on his van, the workmans comp, his medical insurance, his tools, his on going education, his 401-K, liability insurance, his uniforms and about 22 other items I will not bore you with. Think about it this way, if I am sick, you are the man. When your home comfort system fails, the HVAC tech is the man. Like yourself, he deserves to make a solid living for the knowledge he has.9. Air Conditioning Question..If you open doors and windows & keep 3 airconditioners on, what happens?Of course it will increase the cost. That chilled air is going outside after you paid for it. The A/C already mixes fresh air into the air it chills so it does not need new hot and muggy air from those windows. You will save money if you have an electrician come in and add an on-off switch at easy-to-reach height that the staff could use to shut off the A/Cs if they want to open the windows.10. What to look for when buying a new furnace/air conditioning unit?First off, shop around because you will find a big price difference. The things you need to know is how much will it cost to run. What is the proper size for your home? This is critical. Do not let somebody sell you an undersized one because the price sounds good. Make sure the installer shows you how to do basic maintenance such as the proper way to clean the evaporator and condenser coils. If you have central heating you will have the ducts already. If not it will be quite abit costlier. Get many estimates and compare them on price, Btu estimates (Do not volunteer this to an estimater), you will be able to weed out some contractors by this. You can search air conditioners online to see the different fomulas used to determine Btu's. If the price they give sounds overwhelming, they have portable a/c units you can move from room to room, but you need to exhaust the heat to the outside. Sound is the other thing you need to consider
Should My Roommates and I Turn on Central Air Conditioning Or Get 3 Window AC Units?

Maximum temperature drop with air conditioning?15-20 degree drop is in normal range. Most of it depends on the type of system2. How does air conditioning work?No, refrigerant does not get colder in the evaporator but instead it boils into a vapor under this lower pressure side of the system and it's a law of physics that a boiling liquid is changing state to a gas and that causes it to ABSORB heat, so it just feels cold to you. Rubbing alcohol does the same thing on your skin better than water because it evaporates more quickly ( has a lower boiling point)3. Central Air Conditioning in Michigan?You would need the outdoor unit and indoor coil. Probably around $3 - $5 K total4. With central air conditioning, if you shut off the outflow vents in one part of your home, will it make the air conditioning more effective in other parts of your house?If you shut down the ones closest to the thermostat that will cause the thermostat to satisfy less often thereby making other areas get more heat or A/C5. 2001 BMW 740i Sport, my air conditioning/heating system turns on every time i turn on the car. help?yeah what is a cope?6.

Furnace and Air Conditioning Replacement | American StandardWith DIY books, blogs, TV shows and podcasts, there's never been more free content out there to help you take on basic maintenance around the house. However, it's important to remember to follow safety guidelines to avoid accidental injury. If you are planning on troubleshooting problems with your HVAC system yourself, keep these furnace and air conditioner safety tips in mind. One of the most overlooked safety concerns when repairing or maintaining an HVAC system is carbon monoxide poisoning. When not properly maintained and monitored, your HVAC system could quickly become a health hazard either due to a damaged system, a diagnostic problem or inadequate maintenance. Because carbon monoxide is a colorless, odorless gas, it's hard to detect, and prolonged exposure can lead to brain damage and even death. To protect you and your family, keep a carbon monoxide detector with fresh batteries near the furnace at all time. When dealing with any gas-burning system, be sure to follow furnace safety tips by turning off the gas and the power switch and following the manufacturer's maintenance instructions. If you smell gas while maintaining your furnace, do not try to fix the leak or shut off the gas yourself. Leave the house immediately and call your utility company's emergency hotline. When it comes to air conditioner safety, always make sure you turn off the power switch when performing basic maintenance such as clearing debris from the outdoor unit or dusting off the evaporator coils. It's best to have a qualified, licensed electrician service any electrical issue you may be having. Air conditioning units should be inspected regularly to make sure they are not only safe, but also that potential issues can be caught early to avoid costly repair. Preventative maintenance will nearly always save you money in the long run. Of course, the best HVAC safety precaution you can take is to call an American Standard Customer Care dealer. One of our dealers can come out to your home to perform a diagnostic check and repair any issue you may have with your HVAC system. Rather than attempt repairs yourself, our certified and trained technicians will safely service your HVAC unit so you do not have to get your hands dirty, and your furnace and air conditioner continue to keep you comfortable.
What Is an Air Conditioning Tune-Up Checklist?
The end of spring is near, and in a blink of an eye, summer will be upon us in Goose Creek, SC. If you have not already started using your air conditioner, the hum of your unit will soon become a familiar sound. Below are five benefits of spring HVAC maintenance to...1. How to locate air conditioning ducts in drywall ceiling?Turn AC on high. Feel for coldness on places you think they might be2. Air Conditioning: Which kinds of AC units would work for "Outward Casement Windows"?Install a unit through the wall3. Air conditioning broken. Help!!?Oh sorry, it sounds like your speed relay is out on the furnace board. some are a separate relay but these days most are built on to the board. You likely have two power taps going to the connector on the blower motor, I assume you hooked both back up. Generally, when there is a call for cooling it engages two relays. One shuts off the heat so you can not heat and cool at the same time and the other switches those motor taps as cooling is usually at high speed and heat at medium or low. You may or may not have needed a motor but it is not unusual for a bad motor to take out the relay with it. So I do not know that for certain. We know all the fuses and safeties are okay or it would not run in heat. Without being able to put a meter on it and see where you are losing the voltage that is the best I can tell you. Good Luck.4. Central air conditioning?Engine degreaser will eventually evaporate. I would try something like Fantastic, because it wont foam up. You need something that also wo not be effected by water. Try Fantastic. I love the stuff.5. Is Australia really hot, as in unbearably hot? Or is it dry, windy, still bearable all year round without air-conditioning and not humid or sticky like other Southeast Asian countries like Malaysia, Singapore, Indonesia?Here is Victoria today:Snow falls in Melbourne, Victoria and Tasmania as icy weather blows in6. Why does the air conditioning suddenly blow cold air?Google for "bmw e320i heater control valve" when the air con regulates the temperature, it opens and closes the valve. If the valve sticks, it may just give cold or hot air. When this happens, you may be able to check the voltage at the valve connector to see if it is getting the correct input. There may be connection problems also. Usually cycling between maximum hot and cold few times can release it and return to normal (Which would point to a faulty valve).If this happens often you can also test it by setting highest heat setting and regulate temperature with fan speed. If all of a sudden it gives cold air, it may be the connections. Because in highest heat setting valve should stay in same position7. a 1993 jeep 4.0l cherokee sport air conditioning recharge?This is to be carried out by work shops as knowledge and equipment is required8. Air Conditioning:5 possible reasons behind water leakage from air conditioners are:Incorrect AC InstallationImproper AC installation is a very common reason for leakage. An air conditioner should be installed in such a way that the rear end is slightly lower than the front end. A difference of 1 inch is fine. If the unit is too low at front than the condensed water leaks from the front rather than dripping from the rear end. 2. Air leakageIf the AC unit is not properly sealed then warm air from outside gushes inside the unit. The moisture present in warm air get condensed by the cold air inside the unit. This excess moisture buildup inside air conditioner leaks from the unit. 3. Lower outside temperatureDuring rainy season or just before the onset of winters when the outside temperature drops, less water evaporates than it usually does. This results in excess water buildup inside the unit which leaks from your air conditioner.4. Blocked drainageSometimes the drain holes at the rear end get blocked due to dirt and dust. This blockage obstruct the moisture to come out from the rear resulting in the leakage from the front or sides. Regular AC service cleans up the filters and drain hole and prevent water pooling.5. AC Condenser pump brokenWhen the condenser pump inside your air conditioner is broken, it cause the water to leaks from the unit. Call AC repair professionals for condenser or pump repair and stop this water pooling.Understanding the reason behind the improper functioning of your air conditioning system is very important. It assists you in finding the correct repair and remedy for the problem. Air Conditioning: Why do aircons break down and start leaking water?
Troubleshooting to Determine Air Conditioning Repair Need
Finally summer has arrived. You are dreaming of curling up with a good book in your nice cool home. This year, however, your air conditioner is leaking water. Perhaps you are using a window unit, or maybe you have central air. Either way a puddle forming in your basement, or pooling around your window unit, is not a good thing.First let us consider how your unit works. Basically your unit is taking humidity out of the air, humidity that it is turning into water that it drains. Your unit is either draining through a drainpipe or it has a condensate pump. Sometimes, the water does not drain properly and that is what we are trying to figure out. What is causing the water to drain improperly?It is a good idea to look at your unit closely. Can you see where the water is coming from? Is it pooling under the machine? Is it dripping from somewhere inside the unit? If your unit seems like it is wet inside it would be a good idea to turn it off. You may want to call for air conditioning repair. Otherwise perhaps it is a problem with the drain. First let us check your hose. If you are running a central air system it could have a drain hose. Is something sitting on that hose? Maybe that tote of outgrown clothes that you just placed in the basement.

The evaporator coil is stacked on top of the heat exchanger and simply runs air through it passively. The rising temp even with the a/c running suggests to me an evaporator coil that needs a good cleaning and a return air filter that needs changing. A rinse with a water hose would not hurt the condenser.... HVAC systems need yearly check-ups anyway and if your refrigerant level (charge) is not correct, the unit will not cool to its capacity and will waste massive amounts of electricity.What is more efficient: swinging or static vents on an air conditioner inverter?It depends on the room you are airconditioning and the position and type of the vent.nFor most standard rooms you will ventilate the room by blowing in the air somewhere where the wind wo not feel uncomfortable. Then the fresh / cooled air will mix with the already present air well before the air hits anyone. This technique reguires some finesse, but can work beautifully and impressively - and be almost unnoticeable.nBut as a typical indoor A/C inverter is just a box thrown into the window hole or up against the wall somewhere, they are both nowhere near true ventilation, and just deliver cold air into the room by simple brute-force tech. For these things, I would say it takes some experimenting. The knack is always to use more air with a smaller thermal difference, up until the point where the ventilator gets annoyingly noisy. This will mix up the air in the room in the best possible way, making temperature more even and reducing the risk of cold feet or icy winds.nFrom that point on, it's a matter of experimenation. Go for a fair room temperature, do not make the room feel like a fridge. Then it will be fine.What is more efficient: swinging or static vents on an air conditioner inverter?Home air conditioner spotaneously heats...Any ideas?I have not heard such thing before, but I guess following thing is happening in your case. Your air conditioner seems under capacity to cool both floors. As a result it continuously runs and gets heated up. The cooling media which normally is freon / equivalent gas in pipe it self gets heated up due to constant circulation. As result instead of transferring heat and give cool air it reverses. Normally air conditioner is consider of right capacity when it runs in cycle of on/off automatically. When it is running cooling cycle the freon evaporates and passes through copper coils and after some time it swich off and only normal air runs through fan. During this time freon gets cool down for next cycle. You need to get another air conditioner along with this or get higher capacity air coditioner to cool both floors.If you have asthma, does that mean you can't breathe without air?I do not have asthma but even I can not breathe without air. So, what I am trying to say is: Everyone needs air to breathe.Asthma narrows your airways; sometimes completely closing it to movement of air. So, if you have asthma, and if you are under acute attack, it means your lungs will have difficulty moving air in and out to cause adequate oxygen exchange.You will have to take medicines to reverse the narrowing so that you can once again start breathing normallyWill there ever be a day in which we eliminate air turbulence? Or at least make it so that the passengers within the plane do not feel it?No. There wo not .The worlds largest cruise ships and aircraft carriers that are hundreds of times heavier than the largest aircraft get bounced around the ocean like a cork. What chance do aircraft have?The energy in a storm rivals a nuclear blast. That is a lot of energy.The best we can do is find better ways of locating and avoiding turbulence. The problem is there is nothing to see and sensors can not be left floating in the air. Time will tellDoes less gravity means less air density?Yes. Less gravity implies less pressure because the gravity "pulls" the air to the surface of the Earth. And less pressure implies more volume. Ergo, the density of the gases on the atmosphere are less with the new atmosphere pressure.And your second question, the answer is no. It depends of chemical composition (as someone commented above). What we call air, here in the Earth is not the same that the Uranus people call air.Why donu2019t they fill party balloons with hot air instead of helium?The hot air would cool off quickly, and then the balloons would stop floating before you even got them to your car, let alone your party. Even the mylar balloons would exchange heat with the outside air pretty fast. Plus, I do not think you could put hot air into a rubber balloon at all. That would weaken the material and the balloon could pop.Hot air would work in a small balloon, but only for a short time. The air would quickly cool down to match the outside air. Hot air works better in giant balloons because it takes a lot longer for the air in the middle to cool down, and they have that flame thrower there to keep it hot.Why donu2019t they fill party balloons with hot air instead of helium?How does air generate energy, how is it used for leisure activities, and how does it lift things in the air?(1) Wind turbine electrical generators like we've all see, and some very interesting vertical rotors that many people have not seen and probably would not believe work (2) Flying kites, playing with pinwheels, paper airplanes, model airplanes, and depending on how you are defining “air' in this case, even woodwind and brass musical instruments could be considered air-delivered leisure activities (3) Kites through air resistance, airplanes and anything else with a similar wing through the Bernolli effect, para-sailing using a ram-air sail (looks like a huge maneuverable parachute), sky-diving both lifts the plain and brings you to terminal velocity ad slows your parachute. I would *not* consider hot air balloons. That really relies on heat and changing densities to maneuver (as much as a hot air balloon can maneuver).What are some funny air hostess stories?A few that I will list downA passenger tries to convince me that our aircraft (cruising altitude) is being chased by another aircraft...that happened to just flying at the same altitude parallel with us (but because it's at night, you can see their wing tips light).Another argued with me that the lights from another aircraft flying parallel with us is the lights from the stars (we are talking about being 30,000 ft only, you do not get to see stars here). Passenger asking if I could call the captain and ask him to reduce the noise of the engine (he was seated at emergency exit row next to the wing). An elderly lady trying to open the window because she wants fresh air and feel suffocated in the cabin while at cruising altitude.I have more but I can not recall now. I will edit if I can remember any additional story to add in. What are some funny air hostess stories?.how to clean vents for central air?Look in the yellow pages and locate a pro cleaner whose only profession is cleaning air ducts. They have the best and most powerful equipment and know what they are doing. To get an estimate, count all your air ducts and cold air returns.can air enter a water pump?Here's is several reasons why it is bad idea to pump air with water-pump. There are differences in design of an air-pump and a water-pump due to a simple fact that air is compressible, and water is not. Water pumps are very poor at pumping air, so if the intake tube is not filled with water the pump wo not be able to suck hard enough to bring it in. You can very easily damage your water pump, if you run it dry (meaning just pumping air), because without the resistance of the water, the motor turns too fast and also many pump designs rely on the water for its own cooling or lubrication. Pumps can temporarily work with some small air bubbles in them, as long as water is still flowing. This happens when running new-installed pump for the first time and it is normal unless it lasts for more than a minute or two. But even this small bubbles cause micro-strokes on shaft and bearings, shown through excess vibrations and audible gurgling or growling. In a long-terms, this causes so-called material fatigue and shortens the lifetime of a water-pump.Question about an electric air compressor?It could be a number of things however it is not the pressure switch or on off switch because you say it is running. I assume you want the pressure to build to around 100 PSI? 1) Could be an air leak in system. 2) Clogged air inlet 3) Stuck valve in air compressor head 4) Bad Rings 5)Bad gauge not reading over 25 PSI Start simple does it have oil in it? Is it low? Is the belt good not slipping? NO leaks in system including the intercool lines if it is a two stage. I would guess its something simple. How did it quit working right? All of a sudden or gradually?What exactly happens to air pressure in airplane cabins while they are in the air?Assuming the cabin is pressurized most are then the cabin is airtight and pressurized to about 1 atm the barometric pressure at sea level. Otherwise as the place ascended the pressure in the cabin would be in equilibrium with the atmospheric pressure which would continually decrease as you got higher and higher. This would spell disaster for the passengers as they found it more and more difficult to breath, in less dense atmosphere.what are the chemicals released in air Conditioners ?Normally, there are no chemicals released from air conditioners. Air conditioners are simply heat pumps which blow air from inside the house thru a heat exchanger and then transfer that heat to the outside air. The working fluid inside the heat exchanger used to be a type CFC, chlorinated fluoro-carbon. After scientists identified CFC's as a serious problem in the upper atmosphere that influences the heat balance of earth, CFCs have been outlawed for use in air conditioners. They have been replaced by CFC-free materials. I do not know if what the science has concluded about the CFC-free chemicals (they do not do the same bad things CFC's do in the upper atmosphere but I do not know what else they might do.
Air Conditioning Not Turning On?
I do not know what I am talking about, but it sounds like you blew the compressor. It's almost like having to replace the unit. You wo not make that mistake again, will you?.1. The air conditioning in my car is cold (new compressor) but it just won't blow?If no air is coming from the vents on your car, it may be the blower. It is usually located down the dash board in front of the passenger seat. If you know your model car and year you can go to a car part store and ask for this part and they will show you were exactly it is located in you specific car/year/model. It is really easy to take out. Just unmount the cover under the dash board, unscrew the fan/blower, unplug it and Mount the new one. it is important that you turn of the air conditioner first. You can buy a book on how to repair your car in any mayor auto-part store for your car/model. Or search the web in the image section on the web search engines and type "car air conditioning blower mounting". Remember to check first, before you buy the blower/fan for the air conditioner to test if there is electricity going to it. Use a voltage tester to do this2. problem with heating and air conditioning Prius 2009?I attended grammar college in a public college that became into built interior the 1850s. We had warmth. aircon became into presented via a protracted pole with a hook on the tip, it became into used to open the homestead windows, in effective condition right into a recess interior the top of the window so the window would desire to be pulled down. warmth got here first3. What are some ways to cool your home other than air conditioning?buy fans to set in windows ,blowing in, in mornings and nights,blowing out, in afternoons ,buy a free standing swamp fan that uses water you fill with a bucket. Or open windows in morning,shut in afternoons,open in evening. you can put window tinted material on windows also.4. Engine runs rough when I turn on defrost or air conditioning?The problem is there all the time, it's just more noticable when you turn on the defrost. All vehicles with AC use some type of stepper system to raise rpm's about 100 to compensate for the added load of the AC. The AC is tied into the defrost through the evaporator which is located in the heater control box and allows moisture to be removed from the passenger compartment. Do not worry about the serpentine belt or the AC compressor, if they were bad you would hear it. Now to explain the actual problem. I mentioned the stepper, which in your vehicle is controlled by the engine computer. It adjusts fuel injector pulse and ignition timing to raise the engines rpm's. As the rpm's are coming up the fuel system is dumping more fuel into the cylinders, but the idle air system is restricted causing the engine to load up on fuel and stumble or vibrate. The cause for this is a dirty throttle air bypass valve TABV and also called an idle air control valve/IAC. Carbon built up inside this valve restricts the air flow coming into the engine. An engine requires a specific air/fuel ratio and most mechanics over look the air part of the equation. This part is a computerized choke that can be removed, cleaned with a throttle-body cleaner that is O2 sensor safe (about 10 bucks), and reinstalled with a new base gasket (about 3 bucks). It takes about an hour to do. It is located on the intake manifold, is about 3 inches in length, about an inch in diameter, is made of metal and plastic, has a plug-in on the plastic end, and has two 10mm bolts that attach it the intake. It is also a good idea to spray out the throttle air inlet port and the throttle plate. You can check to see how dirty it is, by removing the air inlet hose off the throttle-body, open the throttle plate, and look in the port. You will see a black charcoal colored (carbon) coating on the inside of the TB, the more that is visible the worse the problem is. I know this will correct the problem with your vehicle. Take care and good luck. Christopher
Tell Me If Anyone Has Heard If This Is True Or Not: Just Got an Entire Air Conditioning Unit Install
i dont see y your system will freeze. you can set it to 60 and it will not drop temperature any faster than is able. what might be happening your fan shuts off after several hours of use leaving condenser running still pumping freon in evaporator coil upstairs making t freeze. they might not be able to figure out wat the problem was so they sold you a condenser. run dat unit to the max so you can see wat happens. if it does give them a call1. Is the air conditioning system (air cooling) related to my heater?You may have Fogging on inside Windshield , If You open the Defrost vent; If that leak is in the Evaporator,The Fan Blows across Heater Coil and Evaporator Of Air-Cond, You will have Fog inside windshield,if You use the Defrost which opens door to allow, Air Flow to Glass;If Refrigerant leak is in Eng.Compartment,You can select any position for Heat,no Problem; There is One other way to not have Moisture,If the Air-Conditioner System is Totally Bled down;2. how important is it to have heating and air conditioning returns?the return is what feeds the system the air it needs to move air. the house i assume was built in the 50's at that time they put a return in the basement and that sucked air down from the house. works OK for heat but no so well for ac. by putting in a return system you will draw the hot air out of the rooms farthest away from the furnace allowing them to cool more efficiently. this will also help to eliminate hot spots in the winter. so yes add a return system in. rule of thumb is one return for every feeder. usually on the opposite side of the room.3. 2001 eclipse air conditioning problem?You have a leak in the system. You should have cold air out of the dash vents at around 40 degrees. Have the system recharged with 134a and have dye added. This will help a mechanic locate the leak next time the AC quits putting out cold air. You may be damaging the AC compressor running it with the warning light flashing. Go to the dealer and have it looked at. An hour labor plus the refrigerant4. Air Conditioning?I have it. Mine has gone out for weeks at a time though. open windows during cool parts of the day to chill your house5. Car air conditioning problem?Two tips: first of all, the air conditioning compressor has an electromagnetic clutch. It may be worn out or have a bad wire link. Check these out. Second, and my guess is that it's more likely to be that, it's a refrigeration problem. Have your refrigerating circuit checked by a specialised car refrigeration technician. There's probably a problem with the discharge valve or maybe the freon pressure inside the system is low6. which side the expansion valve of the split air conditioning located?The cold side includes an expansion valve and the cold coil7. Is it a good idea to bypass a heater core this way for colder air conditioning?Some cars it may help depending on if the temp is controlled by water flow, or by air controll doors in the heating system. if it has doors that are working properly, then disconecting the heater hoses would not help. if the doors were out of adj. for some weird reason, then it would help a little or a lot depending on how far out they were, but with out all the air flowing proprly you would not be getting full use of the a/c core. and it should be fix, but no damage would happen if you did unhook them, but you should plug the open pipe plugs off so nothing gets in there and plugs the heater core. if its is just controlled by water flow only, and the valve is leaking internaly then it may help alot to unhook them.8. What's a cheap way to have air conditioning?Open your windows instead9. Help with central air conditioning unit making a loud noise?there is a capacitor inside the outside unit,one half of the capacitor controls the fan and the other half is for the compresor.now if your fan motor is going bad it will do the same thing.it's probably an old unit.if it's a grunting sound when it comes on then thats usually the compressor. the freon may be turning to liquid when it should be vapor which means the valves in the compressor are going out .now you can try one thing andit's no garrentee and that's to have someone come out and completely evacuate all the freon out of the system and hook up a vacuum pump to pull the system down into a vacuum and put fresh freon in it.you can call an heating /air conditioning co. to give you an estimate on what it will cost to do it of if it's a real old unit get a estimate on replacing it.everything is going to 13 seer and 10 seers are being weeded out,eventually your going to have to go that route because you wo not be able to get r22 anymore,it will be r410a ,just like they did with the r12 years ago.thats about all i can tell you,i know it's not all good news but i hope it will help.
Why Do Movie Theaters Always Have the Sound and the Air Conditioning?
The cold air is probably to keep people from falling asleep. Some people still fall asleep during the movie. The sound is probably for the movie experience. Some theaters have the speakers out in from and so the people have o hear what the person is saying when the actors are whispering1. What to do about frozen condensation on air conditioning unit?The unit probably needs to be topped off. The low side pressure should be 68 PSI2. My air conditioning works every once in a while.?Bad electrical connection could be any where. GOOD LUCK3. Does my air conditioning unit have a bad capacitor?Likely is the cap. And for $20, why not replace it. Of course, disconnect the condenser before working on it. You probably have a dual capacitor, short out the terminals with each other to dissipate any stored charge. They can pack a punch. Check an appliance parts store or even places like Home Depot if you need one today. Just match the values.4. Is central air conditioning more efficient than window units?Central air conditioning is overall more efficient than a window unit. The main benefits are a more efficient fan, a more efficient chiller compressor, and more advanced energy-saving features. You really should not have more than 10% duct losses in a typical office building. There are also several different kinds of central air conditioning. Full fresh air AC is not very efficient, however when used as a displacement ventilation system with economisers it can be extremely efficient. Then you have fan coils or chilled beams, where a small amount of unconditioned air is supplied to a room equipped to a fan coil or chilled beam which uses chilled water to deliver cooling, and the air is either passively or actively moved around in the room, that also can be really efficient. You also have mixed-mode AC where the chiller is only used in peak cooling cases, otherwise people are free to open windows to passively cool down rooms. Finally you also have night ventilation, where you use the cool night air to completely chill down the building and rely on the structure's thermal inertia to maintain that temperature well into the day.None of these energy-saving features are possible with window units. Is central air conditioning more efficient than window units?5. How do I get rid of foul odor in vehicle air conditioning?air freshiinger6. home Air Conditioning prob, no one is able to repair my air conditioning and they are giving ridiculous prices?$80 for 2 hrs is not bad as many companies charge a $75 diagnostics charge that only includes 1 hr. If it was low on refrigerant (would explain the not cooling well) then there is a leak. The days of just topping the unit off are over as we now know that R-22 depletes the stratospheric level of the ozone and a leak needs to be repaired. I would imagine that after 2hrs time all the easy find leaks were over and needed to do a more thou leak testing. More and more companies are turning to flat rate billing. Which would explain the $500 leach search. In most of the flat rate leak search prices it is including a pump down or recovery of the refrigerant with only a trace gases left then pressurized with high pressure nitrogen then leach searched with a special electronic leak detector. this price usually includes a guarantee, nitrogen, solder and isolation if required, filter dryer, basic leak repair and refrigerant recharge. Most likely he cannot give you a price for complete repair because he has not pinpointed the leak yet and depending on where that leak is major minor or weather to its repairable or replacement part would be answered after the leak was found. For example a leaking flair fitting would be considered minor, leak in fin-tube of the evaporator coil would most likely be a replacement part. I am not trying to defend the guy as I would have to see the bill and be there to evaluate the system myself but just an in site to how the industry is now operating. It is suppose to simplify so you will know how much you are going to have to pay for each step or level of diagnosis compared to somebody just working and paying by the hour. it makes even playing field if a tech is slow or fast you will pay the agreed price weather it takes an hr or a week to find that leak. Also I am hoping you paid the service fee because many company's today are using a black list for customers known for not paying and sharing that information between them. Remember when its hot outside the companies are busy and charge more when demand is high, best time of year to have system serviced is spring and fall before its hot or cold to have it checked and find problems before they start at the "off time" of year when they are not as busy. Keep in mind that companies that have full page phone book adds are generally more expensive as some of those adds can cost $30,000 per year. That is a lot fo overhead they have to overcome. Check with the Better Business Beau, and ask around your area for who your friends or neighbors recommend. I recommend using a company that employs N.A.T.E. generally the leak would have to he on the high side of the systems and generally at a low point to show up, example small leak at the bottom of condensing coil show large oil spots where a leak at the evaporator coil may show nothing at all and be a large leak. Furthermore Freon is a brand name registered trademark of Dupont Refrigerant is what the systems use more specifically R-22 for residential older systems and R410A for newer systems. The system does not use compressor oil. it uses refrigerant oil specifically for R-22 systems use a mineral oil or Alkylbenzene and R410a systems use Polyol Ester (POE)
Air Conditioning Efficiency - Is Higher Efficiency Worth the Extra Cost?
Air conditioning is not just a luxury item for many houses anymore. When building a new house it is often included without question. There are so many options when it comes to central air in a house. The air conditioner BTU is a big thing to consider. The efficiency of the air conditioner is also a big factor to look at. Many new home builders will include a builder model AC unit in the price of the house. If the homeowner wants to have a better, higher efficiency unit, they have to pay extra for that. How much extra should they pay and still come out with a good deal?There are a few things to check out when upgrading the air conditioning unit. When buying the higher efficiency model it will usually include things like high and low pressure cutout switches in the outdoor condenser unit. This can be very valuable and save the compressor from going bad if there is a problem.That could be worth the extra cost right there. Also with a higher efficiency unit, the indoor air handler will include a higher efficiency blower motor. The ECM motors will run much more efficient then a regular motor. The efficiency is even greater if the motor is run at low speeds much of the time.The most confusing issue with any air conditioning is the SEER rating that the US Government uses to rate air conditioning units. The simplest formula I can use to explain this is that the SEER rating compares the cooling BTU's that are made by the unit per unit (KW) of electricity used. Usually expressed as BTU's/Kilowatt of electric. Of course the more BTU's produce per kilowatt of electric consumed the better off you are.To arrive at a usage number you would have to figure up the number of hours per year that you may be running the air conditioning unit. That can be done by taking the degree day information provided by the weather service for your area and through some fairly complex formula's coming up with usage for your house. I suggest that it may be much easier to just figure how many days you will be running the air conditioner and how many hours a day it might actually run. The specifications provided by the manufacturer of the unit you will use show the electrical usage of the unit. Take the watts per hour consumed by the unit, times the hours run time, divide by 1000 and you will have the kilowatt hour of electric that the unit will consume. Now take that and times it by the number of days a year the unit will run. Then figure that times the cost of the electric per kilowatt hour from your electric company.If with these numbers you find that your pay back will be five years or less than I would for sure go with the higher efficiency unit. Keep in mind also that in some states the electricity costs are going to go up by 50% or more in the next few years. You may want to run the numbers at those higher electricity costs. The farther south you live, the more days you will use your air conditioning unit. Therefore it will be more beneficial to get a higher efficiency unit the farther south you live.Heat Pump units often are rated much higher in efficiency that straight air conditioning units. Especially in the mid to southern climates in may pay to look at a heat pump unit. I will try to address that in the future. Heat Pumps will be a whole separate subject.So to wrap up the thoughts on air conditioning efficiency. As electric prices rise the cost of the higher efficiency units will be much more practical. Higher efficiency air conditioners have more safety controls built into them. You can do some figuring and find out how much more you can spend for a higher efficiency unit and still get your money back in saved electricity. There are many good, better, best options out there. Ask your contractor to quote the prices for the different efficiency units available. If you do not ask usually the prices will be the down and dirty lowest price he can find unit. That rarely is a good thing. If your contractor does not want to quote prices on higher efficiency units, then find one that will. You will not regret it.
5 Different Types of Air Conditioning Systems |
Cooling season is in full swing across the country! Understanding the different types of air conditioning systems available will help you make an informed purchase decision should you need to replace yours this season, and help you understand how each works so you can maximize your system's efficiency. Deciding the best option for your cooling needs can be confusing and exhausting when looking at everything available in the industry. We want to provide you with information that is concise and easy to understand how they operate. Information is knowledge and knowledge is power, so we want to give you the power to buy smart for both your wallet and your needs! Below are the most common types of air conditioning systems and the process by which they operate. Central air conditioners are the most commonly used cooling system in the U.S. This system takes cool air and circulates it through a system of supply ducts and return registers. These supply ducts and registers can be found in many locations: As the system carries the cool air through the home, it becomes warmer as it travels through the system. The air then circulates back to the central air conditioner through the return ducts and registers. A benefit of a central air conditioner is that it helps dehumidify the incoming air but with extreme humidity, you may have to invest in a dehumidifier to help lower the moisture in the air. There are also two different types of central air conditioners to choose from. • Split-system central air conditioner - for this type of system, there are two separate cabinets. One is located outside in a metal cabinet and houses the condenser and compressor. The second cabinet is on the inside of the house and contains the evaporator. Typically, the indoor cabinet contains a furnace or part of a heat pump, which has the evaporator coils installed in the main supply duct of the heat pump or furnace. This system is great for anyone who already has a furnace but no air conditioner. It offers the most affordable option for their needs. • Packaged central air conditioner - the name is a good indicator of what to expect from a packaged central air conditioner. The evaporator, compressor, and condenser are all installed in one cabinet. This cabinet is typically placed on a roof or a concrete slab near the house's foundation. Packaged ones normally include electric heating coils or a natural gas furnace, which eliminates the need for a separate furnace inside. This is a great option for cooling your home or business without having to deal with the ductwork. Other systems require ductwork so that the cool air can travel throughout the space. A ductless mini split air condition does not require ductwork because it has an air conditioner or a heat pump outside that connects to units in the home that handle the cooling being pushed into them from outside. You can control the temperature of a whole home or just one room by controlling the air handlers in each specific area. This allows for more control and a more efficient way to control the temperature and cost of operating the ductless mini split air conditioner. A heat pump is a type of split system that utilizes the functions of both heating and cooling in the home. During the summer months, it provides cool air to flow throughout your house and during the winter months, it supplies warm air to keep you comfortable in the chilly weather. There are two types of heat pumps available: • Air source heat pumps - These pumps pull the heat from the outdoors or release the heat from your home into the outdoors. Air source heat pumps achieve the goal of heat and cool no matter what the weather is. • Geothermal heat pumps - Also known as ground source heat pumps, they pull the heat from or put the heat back into the earth in order to cool and heat your home.Limit of conditional expected value is the conditional expected value of the limit?You should mention why $limlimits_ntoinfty E[X_n|mathcalG]$ is $mathcalG$-measurable but the rest is fine...But I guess you've written it down too complicated.It's faster by: Let $Z := limlimits_ntoinfty E[X_n|mathcalG]$i) obviously Z is $mathcalG$-measurableii) for $GinmathcalG$ it holds $$E[Z1_G] = E[limlimits_ntoinfty E[X_n|mathcalG]1_G] = E[limlimits_ntoinfty E[X_n1_G|mathcalG]] = limlimits_ntoinfty E[E[X_n1_G|mathcalG]] =limlimits_ntoinftyE[X_n1_G] = E[limlimits_ntoinfty X_n1_G] = E[X1_G]$$But from i) and ii) it follows $Z = E[X|mathcalG]$
How to Save Money on a Portable Air Conditioning Unit
Before we go into any detail about saving money on a portable air conditioning unit, you need to ask yourself whether you need a portable air conditioner in the first place. If you are not always in your room or office and are always moving around, then a portable air conditioner will be useful to you.If you really need to get a portable air conditioner, then there are many ways to save money on it. Now let us discuss them in more details:1.Choose the right brand. There are many brands offering portable air conditioners. Portable conditioners from premium brands will definitely cost more than the other brands. It is just like buying a Mercedes car. So if you find a lesser known brand which is offering 30% cheaper, do not be discouraged to buy it.2.Do not be influenced by the sales pitch. Once you have done your research and decided on which brand to buy, don't change your mind. Do not be influenced by what the salesman says. Do your research and make sure that you get the right deal.3.Choose the right type of unit. Portable air conditioners have different specifications. A unit with higher specs will cost more than the others. Therefore, it is important to find out what you really need and ignore all the advanced specifications.4.Shop at the right place. This is important as shopping at the right place will prevent you from paying unnecessary fees. Some shops have items that cost a lot more than the others. Larger chain stores sell more expensive items because they need to cover their employment cost, rental and maintenance cost. You can get the same item at a much cheaper rate if you take your time to visit other stores. So do your research to make sure that you know what you are paying for. Internet is a great place to do your research. Visit forums and blogs to read about the best places to buy portable air conditioners.Before you buy from any store, make sure that the store is reputable and is willing to honor returns if the unit is faulty. Most portable units come with a warranty, so remember to check this out with the provider. Also, ask to test the portable unit on the spot so as to ensure that it is working fine before you bring it home.
