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

Common heater failures include a bad thermostat, tripped fuse/breaker, clogged filter or airflow restriction, dirty burners or coils, failed blower or heating element, and ignition issues like a pilot or thermocouple fault. Heat pumps can stop heating due to low refrigerant, worn motors, or belts. Safety sensors for gas/CO can also shut systems down. Our technicians run diagnostic tests and use high‑quality parts. We serve Chesterton and nearby cities like Valparaiso.

Quick checks:

  • Set thermostat to Heat and raise the setpoint 3–5°F.
  • Replace a dirty filter.
  • Check the furnace switch and electrical fuse/breaker.
