I have central air conditioning and being in Florida I rarely need to turn the heat on. The cooling seems to work fine. I set the thermostat to 70 and if it heats up above 70 it kicks in.
But the heater is not working fine. I set the same thermostat to 70, so the heater should kick in after it drops below 70 but it does not. I see the thermostat temperature go to 65 and it still does not kick on. If I adjust the setting to like 80, then after a few minutes it may come on, or might not. but then it will make it so hot and not turn off until it's way above
Is this a problem with the AC unit or the thermostat? If it's the thermostat is this a defect that needs repair/replacement or a calibration issue? Something I can do myself or require a AC repair man?
Thanks,
MC
