Hi My a/c unit is not working efficiently. I will set it on a desires temp, but it rarely maintains that temp, and it runs constanly. (overnight it reaches the desired temp, but by mid-morning, it is running again, and going up) Two years ago, we replaced the compressor, but not the rest of the unit (which is probably as old as the house -22yrs). We are planning on moving out this fall, so I didn't really want to replace the unit at this point if at all possible. Any suggestions on what to do? How do I know if I need more freon? Also, how much is a condenser unit, and would it be most beneficial to get a new one? Thanks you in advance for your help. J W

It started the first time i used my A/C this summer. Iniatially the fan spinned a bit then stopped and i left it on for few hours hoping that it would restart again. I later found out that it was because the breaker tripped. So i turned it back on, the fan started but no cold air. I once noticed for brief period (half minute) the exposed pipe was frosty, and never seemed like that again ever since. it just feels cooler. I tried to turn it on and off serveral time. every time i reactivated it by turn the thermostat from hight Temp setting to low temp, one of the two breakers tripped. sometimes i couldn't even turn the breaker back on. any clue where i should look at. I noticed two capacitors inside the outdoor unit. I don't see any reset button. Your help is greatly appreciated. Greg
