What Are Common Thermostat Problems That Cause It Not To Work?
Common thermostat failures usually come from thermostat issues, power issues that keep HVAC from turning on, or electrical problems in the control circuit. Dirty air filters and mechanical problems can also make the system seem unresponsive. Our technicians diagnose, explain costs up front, repair with quality parts, and verify operation with thermostat checks and airflow testing.
Quick checks:
- Ensure the thermostat is set to Heat/Cool and Auto.
- Replace thermostat batteries.
- Check the HVAC breaker and furnace/air handler switch.
