Troubleshooting Your Thermostat

closeup of womans hand adjusting the thermostatYour central heating and cooling system is controlled by a thermostat, which tells the HVAC system to turn on and shut off to keep your home’s temperature at the desired level. Here is a quick guide to troubleshooting your thermostat when the system cannot maintain a consistent temperature, is not heating or cooling at all, or cycles on and off too frequently.

Your HVAC System is Not Heating or Cooling at All

If your HVAC system is not turning on, it may not be the system’s fault – it could be the thermostat. Check to see if the circuit breaker is tripped, if the thermostat components are dirty, or if there are loose wires I the thermostat. If you have a digital thermostat, check to see if the battery is still good.

The System is Keeping Your Home at the Desired Temperature

Sometimes the HVAC system turns on, but it doesn’t maintain the desired temperature. Crooked mounting of the thermostat could cause this. It could also happen if the heat anticipator is not set correctly.

The HVAC System Cycles on and off too Frequently

If your HVAC system is continuously cycling on and off, you may have dirty thermostat components. There is also a chance that the heat anticipator in the thermostat is not set correctly.
