Furnace Repair in Hazelwood — Common Questions
Answers to the questions Hazelwood homeowners ask us most.
How much does furnace repair cost in Hazelwood?
Furnace repair in Hazelwood typically ranges from $150 to $700. Igniters and flame sensors are on the lower end; blower motors, gas valves, and control boards run higher. You get a flat, upfront price after the diagnostic — no hourly billing.
Is a furnace problem in Hazelwood an emergency?
It can be. If your carbon monoxide detector is going off, you smell gas, or the pilot flame is yellow or tilted, leave the house and call us immediately. No-heat calls in Hazelwood during freezing weather are prioritized for same-day dispatch.
Do you repair heat pumps in Hazelwood too?
Yes. Our techs are trained on heat pumps, dual-fuel systems, and electric furnaces in addition to gas furnaces. If your heat pump in Hazelwood is stuck in defrost or blowing cold air in heating mode, we can diagnose the reversing valve, defrost board, or refrigerant charge.
"Two other companies told me I needed a whole new system. STL Air Pros actually diagnosed a bad capacitor and a dirty coil, fixed both for a fraction of the cost, and told me my system still had years left in it. Finally an honest HVAC company."
