My Home Central Air Conditioner Is Not Cooling My Home Enough,what's the Poblem?
After you replace the filter, make sure all your louvers are wide open. Then go outside and thoroughly clean the condenser, It may not look dirty, but it is. If you can access the evaporator, clean that too. Finally, close the curtains and roll down the shades1. Is a 6 year old 19 SEER Central air conditioner still considered energy efficient or is it time to upgrade?A six year old system should be in great working order. If it has been well maintained and it has not suffered environmental abuse then, it should last 9-14 more years. 19 SEER is in the top 2/3 of available efficiency today. Conversely, in 5 years time who's to say though.Typically manufactures warrant parts for up to 10 years from date of install. These warranties do require registration of the product with the manufacture (something a majority of contractor fail to do, ultimately it is the homeowners responsibility). If you have purchased the home recently, in some cases the warranty is transferable to the new owner (call the installing contractor to find out).As with any mechanical piece of equipment it is always a good idea to protect your investment by having a certified HVAC professional maintain the equipment at least annually.Example of extreme damage most likely due to an animal urinating on a condenser coil. This kind of damage is not covered by warranty, and would necessitate replacement of at the very least the outdoor unit.Hope this helps.Is a 6 year old 19 SEER Central air conditioner still considered energy efficient or is it time to upgrade?Is A 6 year old 19 SEER Central air conditioner still considered energy efficient or is it time to upgrade?2. Sears wants about $7000 to replace a central air conditioner in Connecticut?Sir, Sears has the biggest markup there is. period. You can get down to almost half that with three bids.3. Which Central Air Conditioner should I go with? Is the 16 Seer worth the extra $1800?I would stick to the Trane unit. The units can only become so efficient and after that, the change becomes so minimal it does not make sense to go higher. I believe our AC increases our bill $30 a month when we run it. Even if you run it for every month, it will take almost 8 years for it to pay for itself. Trane is a more common name and service people should be more comfortable working with them if you ever need. See if Trane offers a higher SEER value, I am sure they do. If it is more sensible than $1800, I would think about it. By the way, are these installed prices? Is it only the condenser portion or do you need a new A Coil as well?4. Which is cheaper to run on a central air conditioner system? Just the system or with both the system and fan.The fan switch is for running the fan continuous. Regardless if the heat or cooling is switched on. If your heating or cooling is uneven throughout the house it might be an advantage to run the fan continuously to circulate better, or if you have allergies and have the better filters it would help keep the air cleaner. Otherwise it will be more expensive to heat and cool with it on because of the electrical consumption of the fan.5. my central air conditioner started leaking water from a plastic hose outside the house. whats up with that?My central air unit leaks when the temperature outside the house is close to the temperature inside the house. Typically at around 72 degrees, which is what we keep the house temperature at. I am not sure if the unit leaks outside, it probably does, but it definitely leaks inside the house from the 2 hoses which go into the basement floor (to a sump I guess). This is an old house, but I've only lived here for a few months, so I do not know all the Idiosyncrasies of the AC unit. It did freeze over once and stopped generating cool air. I would really appreciate your insight on this as it differs slightly than the original question.6. Comfort Maker Central Air Conditioner - what do you think of this brand? Is it Crap or Good?Who makes this model. Sometimes name brand manufacturers make cheaper models and use other brand names. They are usually lower quality low end models
