No-heat repair in Fullerton: what we fix

A furnace that will not run is usually stopped by a safety control doing its job: a limit switch tripped by restricted airflow, a pressure switch that cannot prove the inducer is running, a flame sensor too dirty to confirm ignition, or a door switch not fully engaged. Sometimes it is simpler still, such as a dead thermostat battery or a tripped breaker. We check the simple things first and only replace what is actually failed.

Fullerton customers on our no-heat repair

★★★★★

Had them out for an AC tune-up before summer. Thorough inspection, cleaned the coils, and they found a weak capacitor that would have failed in July. Smart move.

James W., Fullerton
★★★★★

Called at 10 pm on a Saturday with no heat and someone actually answered. The furnace was running again before midnight. Cannot recommend them enough for anyone in Fullerton.

David R., Fullerton
★★★★★

Furnace kept shutting off every few minutes. They found a dirty flame sensor and a clogged filter, cleaned both, and it has run perfectly since. Quick and affordable no-heat repair.

Furnace Not Working / No Heat in Fullerton: frequently asked questions

What should I check before calling?

Make sure the thermostat is on heat and set above room temperature, the furnace breaker is on, the furnace switch on the unit is on, the filter is not clogged and the furnace door is fully closed. If it still will not run, call us.

The burners are not lighting or are shutting off early. A dirty flame sensor, bad igniter or tripped limit switch is the usual cause.
