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.
Orinda's elevation brings cooler, wetter winters than nearby flatland cities, so furnaces run hard from fall through spring. Many sit in crawlspaces, garages or tight closets.
Igniters, flame sensors, pressure switches and gas valves are tested in order, not swapped by guesswork.
HAXX inspects venting and the heat exchanger and recommends shutting the unit down if it is unsafe.
Control-wiring and power problems are traced by a team that also holds an electrical license.

Yes. The Air District rule covers sales of new furnaces from 2029, not repairs of existing ones.
A dirty flame sensor, clogged filter, overheating or a thermostat problem. HAXX checks each one before quoting a repair.
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.
