Igniter and flame sensor faults

Furnaces that click, light and shut off are often a dirty flame sensor or a failing hot-surface igniter.

Short cycling

Overheating from restricted airflow, a dirty filter or an oversized furnace.

PLEASANTON DETAILS

Furnace repair
in Pleasanton.

Pleasanton winter nights often drop to near freezing. Furnaces that sit idle for months tend to show their faults on the first cold week.

01

Ignition and flame sensing

Dirty flame sensors and failed igniters are the most common no-heat causes. Both are tested and cleaned or replaced.

02

Blower and control faults

Weak airflow or short-cycling often comes from the blower motor, limit switch or control board.

03

Safety check

HAXX checks venting and the heat exchanger area and tests for carbon monoxide during service.

GOOD TO KNOW

Furnace Repair in Pleasanton: questions, answered.

Can I keep repairing my gas furnace in Pleasanton?

Yes. The Bay Area Air District's zero-NOx rule affects sales of new furnaces starting in 2029, not repairs of existing ones.

What makes a furnace light and then shut down a minute later?

A dirty flame sensor, a blocked filter or an overheating limit switch are the usual causes. HAXX tests each one.

Should I replace my furnace with a heat pump?

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.

Is it safe to run a furnace that smells like gas?

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.
