A/C shuts down for 2 hours in afternoon
My a/c has stopped working (both the compressor and the blower) at about 1:40 pm and started again at 3:40 the last 2 days. The house is in Palm Desert CA and the outside temp has been over 110F both days. When it stops working I can't even turn the blower fan on from the thermostat. Its an old unit but it doesn't get a lot of use (since it's a 2nd home) and we haven't had problems with it before. By the time the repair guy got here yesterday it had started working again and he couldn't find anything wrong (just a quick once-over though and no $ charged). Any idea what might be causing this?
