My a/c seems to constantly run and doesnt cool down!! The maintanance people in my apt complex looked at it and sent an a/c guy out. he cleaned it out. still had probs. yesterday, I set my thermostat at 80 bc I left. I returned 8 hrs later and my a/c had been running ALL DAY and my thermostat said it was 78?! I have a clock that also tells the temp and its under a fan in my living room...It said that it was 86 degrees. They said that the a/c system outside was tired out and that they were going to replace the whole unit and with it came a new themostat. i came home yesterday and it seemed to be fine (new unit and thermostat working!). today when i went to wk i set it at 80. came home and put it at 78. 6 hours later...its 82 degrees inside?! new thermostat, new a/c unit outside, new coils, new air filter, cold air blowing out, freon okay. WHATS WRONG WITH IT?!
My a/c isnt working right! help!!?
It is very possible that the unit is low on freon; new units often cool initially then run continuously because one or more of the connections is leaking refrigerant and/or there wasn't a sufficient "vacuum" pulled on the system before the refrigerant was installed.
Ask your neighbors how long their units are running for comparison.
If you can't get the problem resolved try contacting the housing authority in your area .
Also try the utility company to see if they have any free energy check personnel that might be able to assist.
Try calling local a/c companies, Perhaps one will check the unit in hopes of obtaining the a/c maintenance contract for the complex.
Try the local university for the "expert". Most newspapers rely on experts in every dept. to verify information. Engineering would be the place to contact.
Universities usually have free legal help.
No reason to pay to live in unsuitable conditions.
Reply:From everything you state it appears that outside air is entering the area that is contolled by the a\c. If you live in a high humidity area that makes it more difficult to maintain cold stable air. If the a\c doesn't cycle,(on\off) every so often, then there is too much humidity or outside air coming into the space. Also it's possible that the a\c unit is too small for the space it is trying to cool. A\C takes the heat out of the air, so if warm air keeps coming in, then it cannot get cold enough to cycle on\off, and will never get cold and stay cold. Hope this helps you to get this fixed. It's too hot!
Reply:Have you changed out the filter? I know that in my home the ac runs longer when the filter gets dirty. I try to change it every 3 to 4 weeks. The cheap 70 cent filters work just fine!
Oh, sorry, I just re read your question and saw that the filter had been changed. I have been told that some of those expensive filters will not allow enough air exchange, thus acting like a clogged filter.
Reply:your thermostat may be placed to high up and is not registering properly
or you need another vent put in to pull the hot air off the ceiling
