Gas furnaces in attics, closets, garages and crawl spaces. Every repair visit includes basic safety checks on the burners and venting.
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.
With cool, foggy weather much of the year, Daly City furnaces log long run times. Many homes still rely on a gas forced-air furnace.
Hot surface igniters, flame sensors, inducer motors and pressure switches wear out with heavy use.
HAXX checks venting, the heat exchanger and carbon monoxide risk before leaving.

Yes. The 2029 Air District rule applies to sales of new gas furnaces, not to repairing the one you have.
Often a dirty flame sensor, a blocked vent or a failing pressure switch. HAXX tests the safety controls to find which 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.
