FAQ
Furnace Repair questions

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.
