Heater & Furnace Repair in Santa Clarita, CA

Furnace repair in Santa Clarita: the usual suspects

Most Santa Clarita furnaces sit idle from April to November. Then the first cold morning arrives, everyone turns the heat on at once, and the parts that dried out or got dusty over the summer give up. Here is what we fix most often.

• Furnace lights, then shuts off after a few seconds. Almost always a dirty flame sensor. Quick to clean, and a sign the furnace is overdue for service.
• No ignition at all. A cracked hot surface igniter, a failed inducer motor or a pressure switch that will not close.
• Blower runs but the air is cold. The burners are locked out, or the filter is so clogged that the furnace overheats and shuts down. See furnace blowing cold air.
• Short cycling. On, off, on again every few minutes. Usually airflow or a limit switch. See furnace short cycling.
• Older wall and floor heaters. Common in older Newhall and Canyon Country homes. We repair them with a full gas safety check. More on wall and floor heaters.

Safety first: what we check on every heater repair

A furnace burns gas a few feet from where your family sleeps, so every repair includes a look at the heat exchanger for cracks, a carbon monoxide test, and a check of the flue and gas connections. If we find a cracked heat exchanger, we tell you plainly and shut the unit down. If your CO alarm goes off, leave the house, call 911, then SoCalGas.

Attic, garage or closet: where your furnace lives matters

In newer Santa Clarita tracts the furnace is usually in the attic, where summer heat bakes the wiring and the drain lines. Older homes often have it in a hall closet or the garage. We bring the right parts for each setup, and we tell you if the install itself is part of the problem, like a missing return or a flue that does not meet code.

Repair or replace your furnace?

Igniters, sensors, motors and control boards are repairs. Replacement makes sense when the heat exchanger is cracked, the furnace is 20 years or older, or you are replacing the AC at the same time and want a matched system or a heat pump. We give you a written price for both options. See furnace installation.

Before you call

1. Thermostat on Heat, set a few degrees above room temperature, fresh batteries.
2. Replace the filter if it is dirty.
3. Make sure the furnace door is closed tight. Many furnaces will not run with the panel loose.
4. Check the breaker and the light switch style service switch next to the furnace.
