Heating Repair — common questions
Do you repair heat pumps as well as furnaces?
Yes. We repair gas furnaces, heat pumps, electric heating, and wall heaters across LA and Orange County — all major brands.
My heater smells like burning — is that dangerous?
A brief dusty smell on the first run of the season is normal. A persistent burning, electrical, or plastic smell is not — shut the system off and call us. If you ever smell gas, leave the building and call SoCalGas first.
Do you offer emergency heating repair?
Yes — 24/7, including nights, weekends, and holidays. Cold nights are exactly when heaters fail, and exactly when we answer.
How do you check for carbon monoxide risk?
On gas furnace calls our technicians inspect the heat exchanger, venting, and combustion as part of the diagnosis. A cracked heat exchanger is a serious safety issue and we treat it as one.
Is your heating repair work guaranteed?
Yes — every repair is backed by our parts & labor guarantee, performed under CA C-20 license #1094200.
