Thanks fir the reply. The cimpressor is even on when I'm using the heat, even tho the A/C light is off. I just checked, and the only way to turn the comp. off is to turn off the fan, and that's not good if you want heat.
The system is designed that way so the compressor will get 'exercised' in cold weather as well....compressor should not run in floor heat mode. If your heater still works so there you go! Do you have NO heat with temp set to hot? Still cold in FL.?
