What Are Common Reasons My Heater Is Not Working in My House?
Common heater failures include thermostat problems, a clogged air filter, a tripped breaker or switch, and ignition or flame-sensor issues. Heat pumps can also stop heating due to outdoor unit freeze or control faults.

Ask about our $149 Heating System Tune-Up and S.A.M. plan for ongoing heating maintenance.
