Thermostat Controls Troubleshooting

Without your thermostat, your HVAC system wouldn’t be able to function. Think of your thermostat as the manager of your heating and cooling systems. When you decide you want to change the temperature in your home, the thermostat is responsible for telling the other components of your HVAC system what to do.

If your thermostat isn’t cooperating, don’t worry. We have gathered support material to help you with the most common thermostat issues so you can easily get your thermostat back on track.
