FAQ
Furnace Repair questions
Do you offer furnace Repair everywhere in Washington?+
Our contractor network covers many Washington ZIP codes. Call with your ZIP code and we will tell you whether a licensed contractor serves your address.
Is a ductless heat pump worth it with baseboard heat?+
Usually yes. It's far more efficient than electric resistance heat and adds summer cooling.
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.
