Do you set the thermostat to your desired temperature but it always feels too cold or too hot in the house?
If the room temperature drops lower or goes higher than the set temperature you set on the thermostat, it usually means that the thermostat is not calibrated or it’s installed in a place where it doesn’t get a good sense of the room air.
The no cost solution is to adjust the thermostat. If this doesn’t work for you call your local heating and cooling expert for a free estimate. Replacing the thermostat is a small and easy fix.
