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.
Pittsburg winters are mild, but most homes still rely on a gas furnace in a closet, garage or attic. Furnaces that sit idle most of the year often fail on the first cold night.
Hot surface igniters, flame sensors and pressure switches cause most no-heat calls.
Weak blower motors and clogged filters also hurt summer cooling when the furnace shares ducts with the AC.
Bay Area Air District rules restrict sales of new gas furnaces starting in 2029. Repairs to existing furnaces are not affected.

Existing gas furnaces can be repaired. The 2029 Air District rule applies to sales of new units, not to repairs.
A dirty flame sensor, a pressure switch fault or overheating from poor 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.
