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.
Many Corte Madera homes still heat with gas furnaces in attics, closets or crawlspaces. Older units fail at the same few parts.
Most no-heat calls come down to a fouled flame sensor, a cracked igniter or a pressure switch fault.
A weak blower or clogged filter trips the high-limit switch and shuts the furnace down mid-cycle.
The BAAQMD zero-NOx rule for furnaces, set for 2029, covers sales of new units, not repairs. A sound furnace can be fixed.

Yes. Repairs are not restricted. The upcoming BAAQMD rule applies to new furnace sales, not to fixing existing ones.
Usually a dirty flame sensor, a blocked filter or flue, or a failing pressure switch. HAXX tests each before replacing parts.
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.
