LA winters are mild until 2 a.m. in January says otherwise. Furnace faults follow patterns — ignition and pilot failures, a blower that runs without heat, short-cycling from a clogged filter or an overheating heat exchanger — and our technicians have seen every one of them. We find the fault, fix it properly, and test the system through full cycles before calling it done.
If your heating is due for retirement, this is also the moment to weigh going electric: a modern heat pump heats the house in winter, cools it in summer, and replaces two aging systems with one efficient machine. From whole-home heat pumps to a ductless mini-split for a single addition, we'll size the right solution for how your home actually lives.
Every furnace visit includes a heat exchanger inspection — a cracked exchanger can leak carbon monoxide into your home's air. It takes us minutes and it's the most important thing we do all winter.

Heating repairs and installations carry labor and material warranties, backed by a satisfaction guarantee from a licensed, bonded California contractor.

Call (818) 780-8288Three quick things: make sure the thermostat is set to heat and calling above room temperature, check the furnace breaker, and look at the filter — a fully clogged filter can trip a safety shutoff. If those don't wake it up, call (818) 780-8288 and we'll take it from there.
More than most people admit. Valley and inland nights drop into the 40s for weeks each winter, and coastal homes fight damp cold that soaks in without steady heat. A properly working furnace or heat pump is what makes January comfortable instead of merely survivable.
In this climate it's often a smart move — a heat pump handles Southern California winters easily, air-conditions all summer, and consolidates two systems into one. If you have solar or want to move away from gas, the case gets stronger. We'll walk you through both options honestly during a free estimate.
The critical items are the heat exchanger (checked for cracks that could leak carbon monoxide), burner and ignition operation, gas connections, venting, and the safety limit switches. We verify temperature rise and airflow too, so the system is safe and running at its best.
