Furnace problems
we fix.
Gas furnaces in attics, closets, garages and crawl spaces. Every repair visit includes basic safety checks on the burners and venting.
Igniter and flame sensor faults
Furnaces that click, light and shut off are often a dirty flame sensor or a failing hot-surface igniter.
Blower runs but air is cold
Limit switches, pressure switches and inducer motors checked in order.
Short cycling
Overheating from restricted airflow, a dirty filter or an oversized furnace.
Noises and smells
Banging, squealing or a burning smell checked before the next cold night.
Safety checks
Venting, heat-exchanger visual check and carbon monoxide concerns raised in plain language.
FREMONT DETAILSGas furnace repair
Gas furnace repair
in Fremont.
Most Fremont tract homes heat with a gas furnace in the garage, attic or hall closet. Fremont winters are mild, so many units sit idle for months and fail on the first cold night.
01
First-cold-night failures
Dirty flame sensors, cracked igniters and stuck pressure switches are the usual culprits after a long idle summer.
02
Safety first
HAXX inspects the flue, heat exchanger and combustion air, and tests for carbon monoxide.
03
Repairs still allowed
The Air District's 2029 limit applies to sales of new gas furnaces, not to repairing the one you have.

GOOD TO KNOW
Furnace Repair in Fremont: questions, answered.
Can you still repair gas furnaces in Fremont?
Yes. Bay Area Air District rules limit sales of new gas furnaces from 2029; repairs to existing furnaces are not affected.
My furnace lights and then shuts off. Why?
Often a dirty flame sensor or a venting problem. HAXX diagnoses it and checks for safety issues.
Should I replace my furnace with a heat pump?
If the furnace is old or the repair is expensive, it is worth pricing a heat pump, which also adds cooling. HAXX can quote both.
Is it safe to run a furnace that smells like gas?
No. Turn it off, leave the house if the smell is strong, and call PG&E or 911. Call HAXX for the repair once the area is safe.
