Hello, I've skimmed through several pages of old posts, and haven't seen anything that quite matched my situation, so I thought I would start a new thread and see if anyone can help me out...
I have a house that's about 15 years old, with the original Carrier HVAC unit. In the 2 years that we've owned the house, this unit has been pretty trouble-free -- last year the blower motor died and was replaced, but that's the only problem we've had... until now.
We have the air conditioning on with the thermostat set to 72 degrees F, outside air temperature ranged from 80 to 90 degrees F today. Up until yesterday, our A/C seemed to be working fine and maintaining 72 degrees inside. But since then, the temperature inside the house has risen up to about 80 degrees, and will not cool down.
Outside, the condenser outside appears to be clean -- the fins are free of debris. The condenser fan is running fine, blowing plenty of air -- but the air does not feel perceptibly warmer than outside ambient air.
Inside, the blower appears to be running properly. But there is only a very small amount of slightly cool air 'trickling' out of the registers. When things were working properly, very cold air would blow pretty forcefully from the vents. I did just replace the filter (which was, admittedly, quite dirty) this evening, but that did nothing to improve the cooling.
Can anybody out there hazard a guess as to what might be wrong with my A/C? Is there anything I can check to try and narrow down what the problem is? Any help would be much appreciated. Thanks!
