Thermostat, power, gas supply, ignition and control-board testing to find why the furnace will not fire.
Furnaces that click, light and shut off are often a dirty flame sensor or a failing hot-surface igniter.
Limit switches, pressure switches and inducer motors checked in order.
Overheating from restricted airflow, a dirty filter or an oversized furnace.
Banging, squealing or a burning smell checked before the next cold night.
Venting, heat-exchanger visual check and carbon monoxide concerns raised in plain language.
Winter nights in Pleasant Hill drop to around 40 degrees, and most older homes here still heat with a gas furnace in a garage, closet or attic.
Dirty flame sensors, cracked hot surface igniters, failed inducer motors and stuck pressure switches cause most no-heat calls.
HAXX checks venting, burners and carbon monoxide on every furnace repair.
Air District rules limit the sale of new gas furnaces from 2029. Repairs remain allowed; the rule matters when you replace.

Yes. The Air District's 2029 limit applies to selling new furnaces; fixing the one you have is unaffected.
A coated flame sensor, a restricted vent or a weak pressure switch is the usual cause. HAXX tests each before quoting.
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.
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.
