The short answer
Prime Choice HVAC Repair Service repairs gas furnaces in Los Gatos homes, including no-heat calls, ignition failures, short cycling, and blower problems. Bay Area Air District rules don't require you to replace a working furnace, so repairing your current system is a valid option.
Los Gatos winters are mild compared with much of the country, but cold, damp nights from late fall through early spring still put a furnace to work. When yours won't light, blows cool air, cycles on and off, or starts making new noises, Prime Choice HVAC Repair Service can help. We're based in San Jose, about 7 miles away, and we repair furnaces for homes throughout Los Gatos in ZIP codes 95030 and 95032. On every call, we find the actual cause, explain it in plain terms, and fix it safely so your home is comfortable again. If a repair doesn't make sense for your system, we'll tell you why.
Common Furnace Problems in Los Gatos Homes
In the Santa Clara Valley, furnaces often sit idle for months during the dry summers, so many problems show up during the first chilly week of fall. Dust settles on burners and sensors, filters get forgotten, and small issues that went unnoticed last spring become hard to ignore. Homes on hillside streets or near lots of trees can also collect more debris around outdoor vents and intakes.
Watch for these signs that your furnace needs attention:
- Burners light, then shut off after a few seconds, which often points to a dirty flame sensor
- The blower runs, but air from the vents is cool or lukewarm
- The furnace won't start at all, or the thermostat seems unresponsive
- Short cycling, where the furnace turns on and off often without warming the house
- Banging, squealing, rattling, or a loud boom at startup
- A burning smell that lasts beyond the first few minutes of the season
- Rooms that heat unevenly, or a sudden jump in your gas bill
What Happens During a Furnace Repair Visit
First, the technician asks what you've noticed and when it started. Then they check the thermostat, filter, and power before opening the cabinet. From there, we test the ignition sequence, inspect the burners and flame sensor, and check the inducer motor and pressure switch. We also look at the blower and its capacitor and read any error codes on the control board.
We check the venting and look for signs of a cracked heat exchanger or poor combustion, because those are safety problems, not just comfort problems. Before any work begins, you'll get a clear explanation of what's wrong and what your options are. Many common repairs can be done on the same visit when the part is on hand, such as cleaning a flame sensor, replacing an igniter, or swapping a failed capacitor.
If you smell gas, leave the house and call your gas utility or 911 from outside before calling us. If your carbon monoxide alarm goes off, get everyone outside and call emergency services.
Repair or Replace? What Bay Area Rules Mean for Your Furnace
Many Los Gatos homeowners ask whether new air quality rules mean they have to get rid of their gas furnace. They don't. The Bay Area Air District's appliance rules don't require replacing working equipment. They apply only when an existing furnace fails or is replaced. Repairing your current furnace keeps it in service.
The rules do matter for planning. Under Rule 9-4, natural gas furnaces manufactured starting in 2029 must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when a furnace is replaced after that date. If your furnace is older and needs a major repair, weigh that cost against replacing it, and think about what you'd want to install later.
Incentives are worth checking, too. The federal 25C tax credit for heat pumps covered only systems placed in service before December 31, 2025, so it isn't available for new installations. BayREN and your local clean energy provider may offer heat pump or electrification incentives. Amounts change with each funding cycle, so we confirm the current offer before including it in any quote.
Simple Steps to Keep Your Furnace Ready
With our mild, damp winters, a furnace may run only on cold mornings and evenings. That start-and-stop pattern is hard on igniters and sensors. A few habits help:
- Replace or clean the filter before heating season, and check it every month or two while the furnace is in use
- Keep the area around the furnace clear of stored items, especially in garages and closets
- Make sure furniture and rugs aren't blocking supply vents or return grilles
- Check that outdoor exhaust and intake pipes are free of leaves, nests, and debris
- Test your carbon monoxide alarms and replace the batteries
- Run the heat briefly in early fall so problems show up before the first cold night
