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 in Martinez are wet and cool with occasional frost. Many homes still heat with gas furnaces in attics, hall closets or crawlspaces.
Dirty flame sensors, failed igniters and bad pressure switches are the usual no-heat causes. HAXX tests them before ordering parts.
Weak airflow from a running furnace usually means a worn blower motor, a failed capacitor or a faulty control board.
The Air District's zero-NOx rule for furnaces, starting in 2029, covers the sale of new units. Repairing your current furnace is not affected.

Yes. The Bay Area Air District rule applies to new furnace sales from 2029, not to repairs of existing equipment.
Common causes are a dirty flame sensor, a clogged filter, an overheating heat exchanger or a thermostat issue. HAXX checks 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.
