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.
Winters here are mild, so a furnace in the garage, attic or hall closet can sit idle for months before the first cold snap brings it back on.
Ignitors, flame sensors and pressure switches often fail when a furnace starts after a long idle season.
Weak blower motors and clogged filters cause overheating lockouts. HAXX checks airflow along with the burner.
Bay Area Air District rules limit sales of new gas furnaces starting in 2029. Repairs to existing furnaces are not affected.

Yes. The Air District's 2029 rule covers the sale of new furnaces, not repairs to existing ones.
A dirty flame sensor, a failing pressure switch or restricted airflow are common causes. HAXX tests each one.
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.
