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.

GOOD TO KNOW
Furnace Repair in Fairfield: questions, answered.
Can I keep repairing my gas furnace?
Yes. The 2029 Air District rule covers the sale of new furnaces, not repairs to existing ones.
Why does my furnace turn on and then shut off?
A dirty flame sensor, overheating from poor airflow or a failing pressure switch are the usual causes.
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.
