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

Common heater failures usually come from thermostat settings or batteries, a tripped breaker or furnace switch, a clogged air filter, ignition or flame-sensor faults, or blocked vents/returns. Low refrigerant affects heat pumps. Lack of annual maintenance can cause short cycling or poor airflow. If you’re in Champaign or Mahomet, we service all major furnace and heat pump brands.

Quick checks: - Set thermostat to Heat and fan to Auto; replace batteries. - Replace a dirty filter. - Verify breaker and furnace switch are ON.
