Furnace Repair in Orange County, CA

Common gas furnace failures

• Hot-surface ignitor cracked or worn out — the most common no-light cause
• Dirty flame sensor: the burner lights, then shuts down a few seconds later
• Failed draft inducer motor or a blocked pressure switch hose
• Blower motor or capacitor failure — heat builds but never moves
• Limit switch tripping from a clogged filter or closed-off returns
• Gas valve, control board or rollout switch faults

The safety check we won't skip

Every furnace repair includes an inspection of the heat exchanger and the venting. A cracked heat exchanger can let combustion gases — including carbon monoxide — into the air your blower distributes through the house. If we find one, we shut the furnace down and tell you straight, even when that's not the answer anyone wants. We won't return a furnace to service that isn't safe to run.

Repair, or is the furnace done?

An ignitor or a flame sensor on a well-maintained furnace is a straightforward repair worth making. A cracked heat exchanger, a failed gas valve on a twenty-year-old unit, or a third significant repair in as many seasons is a different conversation. We quote both paths and give you our honest read — then it's your call, not ours.

What keeps a furnace out of trouble

• Change the filter on schedule — restricted airflow causes more furnace failures than anything else
• Keep supply and return vents open and unblocked by furniture
• Run the heat briefly in early fall, before the first cold night, so problems surface on your schedule
• Have a working carbon monoxide alarm on every floor with a gas appliance
