Furnace Brands We Repair in Sacramento
Igniters, flame sensors, inducer motors and control boards for the furnaces actually installed in Sacramento homes.
Three generations of Sacramento houses, three kinds of furnace problem
Sacramento winters are not brutal, but they are damp and long enough that a dead furnace in December is not something people wait on. Lows sit in the high 30s for weeks, the tule fog does not lift for days, and a house with no heat gets cold in a way the thermometer does not fully explain.
What we work on depends almost entirely on when the house was built:
- East Sacramento, Land Park, Curtis Park, Oak Park. 1920s to 1940s bungalows and Tudors. Many still have a floor furnace or wall heater, or a central furnace retrofitted into a closet or crawlspace with ducts that were never meant for it.
- Arden-Arcade, Tahoe Park, South Land Park, Rosemont. 1950s and 60s ranch homes, usually on their third furnace, with the original return and a filter slot nobody can reach.
- Natomas, North Natomas, the Pocket, Elk Grove side. 1990s to 2000s tract homes with the furnace in the attic, where a clogged condensate line or a failed inducer turns into a ceiling stain before anyone notices the heat is out.
The diagnostic is a flat $69 anywhere in the city, and it comes off the repair. Permits go through the City of Sacramento for city addresses and Sacramento County for Arden-Arcade, Carmichael and the other unincorporated pockets. We handle both.
Floor furnaces and wall heaters in the older neighborhoods
A floor furnace is a gas heater set into the floor with a grille over it. A wall heater is the same idea mounted in the wall between two rooms. Sacramento has thousands of both, mostly in homes built before 1950, and they are still heating houses in Land Park and East Sac every winter.
We repair them when it makes sense and we are honest when it does not:
- Pilot and thermocouple problems are the usual reason one stops working. That is a normal repair.
- Gas valves on units this old are often no longer made. If the valve has failed, we tell you before we quote, because a used replacement is not something we will install.
- Cracked heat exchangers and rusted burners mean the unit is done. A floor furnace vents into the room you stand in, so we do not take chances with it.
When one of these is at the end of its life, the conversation is usually not about another floor furnace. In a house with no ducts, a ductless heat pump heats and cools the same rooms without tearing the house apart, and the SMUD rebates described below apply to it. For homes that already have ducts, see furnace installation in Sacramento.
What actually fails in a Sacramento furnace when the fog rolls in
Most furnace calls in Sacramento come down to a short list of parts, and the list is different from what breaks on an air conditioner in July.
- Hot surface igniter. The furnace clicks, the blower runs, no flame. The igniter is a ceramic part that simply wears out. Common on 8 to 15 year old units, and a quick fix.
- Dirty flame sensor. The burners light for three seconds and shut off, over and over. Cleaning it takes minutes. Replacing it is not expensive either.
- Pressure switch or inducer motor. The furnace tries to start and gives up before the burners light. In Natomas attic units this is often a condensate line clogged with sediment tripping the switch, not a failed part.
- High-limit switch tripping. The furnace heats, shuts down early, restarts. Nine times out of ten the cause is a filter that has not been changed or a return that is too small for the furnace, which is the standard story in a 1950s Arden-Arcade ranch home.
- Control board. Intermittent, hard to pin down, and the one we test twice before we replace.
Every furnace visit includes a combustion check and a carbon monoxide reading at the registers. If the heat exchanger is cracked, we show you, we shut the gas to the unit, and we do not talk you into a repair on it. That is the one job we turn down. For the summer side of the same house, see AC repair in Sacramento.
If the furnace runs but the air is cold, work through our checks for a furnace blowing cold air before you call. Half of those calls end at the thermostat or the filter. If it runs for a few minutes and stops, over and over, see why a furnace keeps turning on and off. And if it bangs when the burners light, our guide to furnace noises explains why that one cannot wait. If it does nothing at all, start with our seven checks for a furnace that will not turn on.
SMUD rebates, PG&E gas, and when the repair should be a heat pump instead
Sacramento gets its electricity from SMUD and its gas from PG&E. That split matters when a furnace repair turns into a replacement decision, because SMUD pays homeowners to leave gas heating behind and PG&E does not pay you to stay.
At the time we wrote this, SMUD lists $3,000 for a variable-stage heat pump and $2,000 for a two-stage unit when it replaces a gas furnace, with a further $2,000 available toward a panel upgrade. The equipment has to be installed by a contractor in the SMUD network, and the amounts change, so we confirm the current figures when we quote rather than promising a number here. Details on our heat pump installation in Sacramento page.
The city itself has required all-electric new construction since January 2023 and adopted a plan in 2024 to move existing buildings off gas by 2045. Nothing in that plan requires you to replace a working furnace today. But it does mean a fifteen-year-old furnace with a cracked heat exchanger is a natural moment to run the heat pump numbers, and we run them side by side with the repair.
Not sure whether this is a repair or the end? Our guide to when to replace a furnace covers the four questions we ask.

Furnace Repair in Sacramento: Common Questions
The diagnostic is a flat $69 and it goes toward the repair if we do the work. Igniters, flame sensors and pressure switches are inexpensive parts and a short visit. Inducer motors and control boards cost more. A cracked heat exchanger is not a repair we do, and we say so before quoting anything.
Yes, in the older neighborhoods like Land Park, East Sacramento and Oak Park we see them every winter. Pilot and thermocouple problems are routine. If the gas valve or heat exchanger has failed on a unit that old, we tell you plainly, because parts are often no longer made and we will not install used ones.
Usually a dirty flame sensor. The furnace lights, the sensor cannot confirm the flame, and the control shuts the gas as a safety measure. Cleaning it takes minutes. If it keeps happening after a cleaning, the sensor or the board is next on the list.
It depends on the part. An igniter on a fifteen-year-old furnace is a sensible repair. A cracked heat exchanger or a failed inducer on the same unit is where we price the repair next to a replacement, and in Sacramento that comparison includes SMUD heat pump rebates, which change the math more than most people expect.
