How it works
Combustion-safe diagnostic
CO meter on every call. We verify draft, flame rectification, inducer RPM, and gas pressure before touching anything.

Frequently asked — furnace & heat pump service in Fullerton
Why does my furnace short-cycle?
Dirty flame sensor, failing pressure switch, restricted return airflow, or oversized equipment. We verify all four on the first diagnostic visit.
Can you service heat pumps in Fullerton's colder snaps?
Yes. Fullerton's mild winters suit heat pumps well — we tune balance-point settings and stage auxiliary electric or gas heat so efficiency doesn't collapse below 35°F.
Is it worth switching from gas to a heat pump?
For many Fullerton homes, yes — especially if you qualify for current federal + utility rebates. We walk the 10-year total-cost math before recommending it.
What's included in an annual heating tune-up?
22-point inspection: combustion analysis, CO test, flame-rectification reading, gas pressure verification, blower amp check, ductwork leak scan, thermostat calibration, filter, and a written report. $99 for existing customers, $149 otherwise.
