The short answer
FrostPoint AC Repair repairs gas furnaces in Los Gatos homes, from ignition and flame sensor failures to blower, airflow, and safety switch problems. We find the cause, explain your repair options, and tell you how current Bay Area Air District rules affect any decision to replace instead of repair.
When a furnace quits on a cold, damp Los Gatos evening, you want to know what failed, what it will take to fix, and whether the repair makes sense for your home. FrostPoint AC Repair is based in San Jose, about 6 miles northeast of Los Gatos, and we handle furnace repair for homes throughout ZIP codes 95030 and 95032. We diagnose the problem, explain it in plain terms, and give you your options before any work starts.
Furnace Problems We Commonly Fix in Los Gatos Homes
The Santa Clara Valley has mild, damp winters, so many Los Gatos furnaces sit unused for months and then run hard during a cold stretch. That pattern causes its own set of failures. Parts that worked fine last winter can stick, corrode, or collect dust over a long, dry summer. These are the issues we see most often:
- Furnace runs but blows cold or lukewarm air
- Igniter or pilot that won't light, or burners that light and then shut off
- Dirty or failing flame sensor causing short cycles
- Blower motor that hums, runs constantly, or won't start
- Tripped limit or rollout switches from restricted airflow or overheating
- Clogged condensate lines or drains on high-efficiency furnaces
- Thermostat wiring or control board faults
- Unusual noises such as banging at startup, squealing, or rattling
What Happens During a Furnace Repair Visit
We start by asking what you've noticed: when the problem started, whether it happens every cycle or only sometimes, and any error codes the furnace is flashing. That history often narrows the cause quickly.
Next, the technician checks the thermostat, power, gas supply, and filter, then works through the ignition sequence, burners, flame sensor, blower, and safety controls. On high-efficiency units we also check the inducer motor, pressure switches, and condensate drainage. We look at the venting and heat exchanger for signs of safety concerns, because a furnace that runs isn't always a furnace that runs safely.
Once we know the cause, we explain what failed and why, describe the repair, and answer your questions before doing the work. If a part needs to be ordered, we tell you that up front and make the system as safe as possible in the meantime.
Repair or Replace? What Bay Area Air District Rules Mean for You
Many Los Gatos homeowners have heard about new Bay Area Air District rules for gas furnaces and worry they'll be forced to replace a working system. They won't. The Air District's appliance rules do not require replacing working equipment. They apply only when an existing furnace fails or is replaced.
What changes is the future. Under Rule 9-4, natural gas furnaces manufactured from 2029 onward 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, it's worth thinking about whether to fix it now or plan for a heat pump.
On cost help: the federal 25C tax credit covered qualifying heat pumps placed in service before December 31, 2025, and it isn't available for new installations after that date. Local help may still exist. Bay Area homeowners can check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before we mention it in any quote.
For most straightforward problems, like a failed igniter, sensor, or blower capacitor, repair is the sensible choice. We give you an honest read on your furnace's condition so you can decide.
Getting Ahead of the Next Cold Snap
Because Los Gatos winters are mild, it's easy to forget the furnace until the first cold night. A few simple habits help. Replace the air filter before the heating season, since a clogged filter is one of the most common causes of overheating and short cycling. Run the heat briefly in early fall so you find problems before you need the furnace. Keep the area around the unit clear, and make sure supply and return vents aren't blocked by furniture or rugs. If you smell gas, leave the house and call your gas utility from outside before calling anyone else.
