Furnace Repair FAQs
Why won't my furnace turn on?
The most common causes are a thermostat setting, a tripped breaker or furnace switch, a clogged filter, or blocked outdoor vents. If those all check out, it's usually an ignition or safety control problem that needs a technician.
How often should a furnace be serviced?
Once a year, ideally in the fall before heating season starts.
Should I repair or replace my furnace?
Most furnaces last 12 to 20 years with regular maintenance. If yours is in that range and needs repairs more often, can't keep the house warm, or your gas bills keep climbing, replacing it is often the smarter move. We'll give you an honest read either way.

Yes. Our certified technicians work on all major brands and systems, residential and commercial.
Do you offer after-hours furnace repair?
