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

Most heater failures come from simple issues you can check. Verify the thermostat mode and setpoint. Replace a clogged filter. Check the furnace switch and breaker. Make sure the gas valve is on or the heat pump has power. Look for a tripped safety switch or blocked intake/exhaust. If the blower runs but no heat, the igniter or flame sensor may need service. We offer 24/7 emergency heat help in Crawfordsville, Lafayette, and Lebanon, plus fall tune-ups to prevent surprises.
