When your heat quits in the middle of a cold snap, you don’t want a phone tree and a three-day wait. We handle furnace repair across San Jose, from the flat-roof tracts of the east side to the larger properties up in the foothills. Our technicians know this valley’s housing: postwar ranch homes that were retrofitted with ductwork long after they were built, newer infill townhomes, and rural properties that never got a gas line at all. That matters when your heat is out. Call (833) 573-8799. We answer 24/7.
Why San Jose Homeowners Call AC Repair Sunnyvale for Furnace Repair
If a furnace is acting up in San Jose, our furnace repair team is one call away, and the first thing we do is figure out whether a repair actually makes sense before anyone talks about a new unit. That’s not a sales line. We work on nine major brands, so we aren’t steering you toward the one with the best dealer incentive. If a fix will get you through the next several winters safely, we’ll say so.
San Jose homeowners also get the benefit of a company that handles both heating and cooling. When your furnace fails, you don’t want to hunt down a separate contractor who only touches the heating half of the system. One company, one point of accountability, whether the problem is the furnace or the AC that shares the same ducts.
Our technicians have up to 10 years of experience, and a good share of that has been spent in San Jose’s older single-story neighborhoods, where furnaces are often tucked into a closet and ductwork runs through an attic not built for it. That’s the kind of thing you only learn by getting up there. Fast dispatch from 7am to 7pm, Sunday through Friday.

Emergency Furnace Repair in San Jose
Emergency Furnace Repair in San Jose usually means a system that stopped heating overnight, and the fix starts with getting eyes on the actual fault rather than guessing. A technician checks ignition, airflow, the flame sensor, the blower circuit and the heat exchanger, then tells you what’s wrong in plain terms. Most emergency furnace repairs in San Jose fall in the $175 – $825 range, and the written estimate sets the final price before any work starts. Call (833) 573-8799.
What the first visit covers
We walk through the system before touching anything: thermostat call, ignition sequence, blower operation and combustion. In the foothill ZIPs, that also means checking propane supply and the orifices for dust. By the end of the visit you’ll know what failed and what it costs to fix it.
When heat loss is urgent
A furnace that won’t light in cold weather is a health concern, not a comfort complaint, especially in homes with older residents or young kids. If you’ve noticed a gas smell or soot around the unit, stop using it and call us right away. Don’t open the panel and start poking around. Combustion components and gas valves need a trained technician.
Furnace Maintenance in San Jose
Furnace Maintenance in San Jose is worth more than most homeowners think, because the properties up around the Diablo Range foothills work their equipment harder than the flat, sheltered tracts. A tune-up covers combustion analysis, static pressure checks, filter and blower inspection, and a look at the heat exchanger. The typical tune-up in San Jose runs $95 – $235, and you get a written report of what was actually found. Our technicians aren’t paid on what they sell.
What a tune-up actually catches
The visit usually surfaces small problems before they become emergency calls: a dirty flame sensor beginning to short-cycle the burner, a blower capacitor drifting out of spec, or a heat exchanger crack that’s only visible under close inspection. In dusty, exposed settings, orifices clog faster than homeowners expect.
How often we’d recommend it
For a heat-and-cool system on a normal schedule, an annual visit before heating season is sensible. For a rural property that runs the furnace hard against open, unsheltered exposure, or one that heats a workshop or outbuilding on the same system, a closer look each season pays for itself. Wear shows up early when a system runs longer than it was sized to.
Trusted Brands We Service in San Jose
Whether your furnace is a Lennox, a Goodman, a Rheem or a York, we know how it’s put together and what usually fails on it. We’re factory-familiar with the nine brands most widely installed in homes across San Jose, and we don’t stock one manufacturer’s parts to the exclusion of another. When a part is needed, we source it and schedule the follow-up visit. No waiting weeks for a dealer appointment. No steering you toward a replacement because that’s what we’d rather sell. Repair or replace, we’ll tell you which one actually makes sense for your system and your home.

AfterCommon Furnace Repair Problems We See in San Jose Homes
- Propane ignition failures in rural foothill homes. In exposed settings with no wind shelter, dust and debris get pulled into the burner compartment, and propane orifices clog faster than most homeowners expect. A dirty flame sensor or restricted orifice is a common culprit when the furnace won’t light or keeps dropping out mid-cycle.
- Heat exchanger cracks in drafty, unsheltered properties. A furnace that cycles hard against infiltration in a foothill home doesn’t get a break, and repeated cycling stresses metal over time. We treat a cracked heat exchanger as a safety issue, not a minor fault, and recommend a full inspection whenever combustion looks off.
- Blower motor capacitor failure in older units. Homes that push one system to heat a main house plus an outbuilding, or a converted workshop, run the blower longer and hotter than it was designed for. A weak capacitor is a $200 – $400 class of repair in most cases, but only if it’s caught before the motor itself burns out.
- Undersized return-air paths in postwar tracts. Many 1950s and 1960s single-story homes in San Jose’s east and south neighborhoods were built without central HVAC, and the furnaces retrofitted later sit in closets with returns that were never sized for the ductwork added around them. That restricted airflow drives short cycling and uneven heat.
Pricing for Furnace Repair in San Jose, CA
Furnace repair in San Jose typically runs $175 – $825, with the final price set by the written estimate you get before we start. What moves the number: whether the part is a common ignition component or a propane-specific item ordered in, how accessible the unit is inside a closet or attic, and whether the underlying issue is a single failed part or a system that’s been running out of spec for a while. A tune-up, if that’s what makes sense, is $95 – $235. We don’t charge for the estimate, and we don’t add fees for the visit.

FAQs About Furnace Repair in San Jose
Yes. We service propane furnaces in San Jose’s foothill areas. The key difference is that propane-specific parts often need to be ordered, and properties out toward the Diablo Range and the Santa Cruz Mountains sit at longer service distances, so we plan the visit around that. Expect a slightly longer schedule between diagnosis and repair than on the flat, gas-served tracts near 95122, but the process is the same. Call (833) 573-8799 for a free estimate.
Once a year before heating season is the baseline, and for exposed foothill properties it’s worth taking seriously. Homes without wind shelter run the furnace harder through the winter, which means faster wear on the flame sensor, the blower motor and the heat exchanger. A tune-up at $95 – $235 typically catches small faults before they turn into a no-heat call. Book a visit before the first cold week lands.
Sizing takes more than a square-footage number. A drafty, unsheltered property, or one where the furnace has to condition a converted workshop or outbuilding on the same system, needs a load calculation that accounts for infiltration, exposure and how the space is actually used. A system sized by rule of thumb on a property like that will oversize and cycle hard, which stresses the heat exchanger. Call us and we’ll walk through the right approach.
Short cycling is the furnace heating past its setpoint, hitting a safety limit, or losing the flame signal, and it gets worse as the outdoor temperature drops because the run times get longer work out of the same system. Common causes in rural San Jose homes include a dirty flame sensor, a weak blower capacitor, and restricted airflow from an undersized return path. It’s diagnosable, and it’s worth fixing before a long cold stretch. Call (833) 573-8799 for an estimate.
Yes, we handle the heating side whether the system is a gas furnace, a propane furnace, or a heat pump. On a heat pump we verify refrigerant charge and airflow at the same visit, since those are the two things that most often cause a heating call in the first place. Whether your furnace gave out or your AC won’t start, one call handles it. Estimates are free.
