FAQ
Furnace Repair questions
Do you offer furnace Repair everywhere in North Carolina?+
Our contractor network covers many North Carolina ZIP codes. Call with your ZIP code and we will tell you whether a licensed contractor serves your address.
What is a dual-fuel system and is it common in North Carolina?+
It pairs a heat pump with a gas furnace. The heat pump handles mild weather and the furnace takes over in cold snaps. It's common in the Piedmont.
Why does my furnace turn on then off right away?+
The most common reason is a dirty flame sensor, which can't prove the flame so the board shuts the gas off. Other causes are a weak pressure switch or a blocked vent.
Is a cracked heat exchanger dangerous?+
It can be, because it may let combustion gases mix with house air. A tech will usually shut the furnace off and red-tag it until it is repaired or replaced.
