Furnace Repair FAQ
How much does furnace repair cost?
Common furnace repairs run $150–$700, an ignitor, flame sensor, or capacitor is on the low end; a blower motor or control board is higher. A cracked heat exchanger is a safety issue that usually means replacement.
Why is my furnace blowing cold air or not turning on?
Frequent causes are a dirty flame sensor, a failed ignitor, a tripped safety switch, or a thermostat problem. A tech diagnoses safely, with gas, a cracked heat exchanger must be ruled out for carbon-monoxide safety.
Is a furnace problem dangerous?
It can be. Gas furnaces can leak carbon monoxide from a cracked heat exchanger, so any smell of gas, soot, or CO alarm means shut it off and call a pro. Working CO detectors are essential.
