What Are Common Reasons My Heater Is Not Working in My House?

Common heater failures usually come from settings, airflow, power, or ignition issues. Check that the thermostat is set to Heat and above room temperature. Replace a dirty filter to restore airflow. Verify the furnace switch and breaker have power. Open all supply and return vents. If it clicks but won’t fire, the igniter or flame sensor may need service. A technician can confirm the cause and price on site in Denver or Aurora.

Quick checks:

• Set thermostat to Heat; try new batteries.
• Replace the air filter.
• Check switch/breaker.
• Open all vents.
