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.
SAN JOSE DETAILSFurnace repair
Furnace repair
in San Jose.
Most San Jose homes heat with a gas furnace, often in the attic or a hallway closet. Cold snaps bring the same failures every year.
01
Common failures
Igniters, flame sensors, pressure switches and inducer motors cause most no-heat calls, and most are same-visit repairs when the part is available.
02
Attic furnaces
Many 1950s to 1970s homes have attic furnaces with long flex ducts. Airflow and venting are checked on every visit.
03
Repair or replace
If the heat exchanger is cracked or repairs keep adding up, compare a new furnace with a heat pump. Bay Area rules from 2029 will limit new gas furnaces.

GOOD TO KNOW
Furnace Repair in San Jose: questions, answered.
Do you repair attic furnaces in San Jose?
Yes. HAXX repairs attic, closet and garage furnaces throughout San Jose.
Is it still OK to replace a gas furnace with a gas furnace in San Jose?
Today, yes. Bay Area Air District rules taking effect in 2029 will limit new gas furnaces, so it is worth pricing a heat pump too.
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.
