The short answer
PerfectFix HVAC Services repairs gas furnaces in Los Gatos homes, including ignition failures, airflow problems, and tripped safety controls. Bay Area Air District rules do not require you to replace a working furnace, so repair is often the right call. If replacement makes more sense, we'll explain your options, including heat pumps.
Los Gatos sits on the southwestern edge of the Santa Clara Valley, where winters are mild and damp rather than harsh. Many homes here run the furnace only on cool mornings and chilly nights, so a system can sit idle for months and then refuse to start, short-cycle, or blow lukewarm air on the first cold evening of the season. PerfectFix HVAC Services handles furnace repair for homes across Los Gatos in ZIP codes 95030 and 95032, about 8 miles southwest of our San Jose base. We find the actual cause, explain it in plain terms, and fix what's needed. If a repair doesn't make sense for your furnace's age and condition, we'll tell you that too.
Common Furnace Problems in Los Gatos Homes
Because the heating season here is short and mild, many furnace problems come from long stretches of non-use rather than heavy wear. Dust settles on burners and sensors, filters get forgotten, and small parts that worked last winter can fail on the first startup. Damp winter air can also add to corrosion on older components and venting.
These are the issues we see most often on furnace repair calls:
- Furnace clicks or tries to light but shuts off within seconds, often from a dirty flame sensor or failing igniter
- No heat at all, from thermostat, control board, or gas valve problems
- Blower runs but the air coming out feels cool or lukewarm
- Short cycling, where the furnace turns on and off repeatedly, often tied to a clogged filter or overheating limit switch
- Pressure switch or draft inducer faults that prevent the burners from lighting
- Burning dust smell that doesn't fade after the first few minutes of use
- Rattling, squealing, or banging from the blower motor, belt, or ductwork
How We Approach a Furnace Repair
We start by listening to what you've noticed: when the problem started, what the furnace does, and any sounds or smells. Then we check the system step by step, from the thermostat and filter through ignition, burners, blower, safety switches, and venting. Many furnaces store error codes that help narrow things down, and we confirm those findings with hands-on testing instead of guessing.
Before any work begins, we walk you through what we found and what we recommend. Safety comes first. If we find signs of a cracked heat exchanger, a venting problem, or anything that could let combustion gases into your living space, we'll explain the risk clearly and won't leave the furnace running in an unsafe condition.
Repair or Replace? What Bay Area Rules Mean for You
Many Los Gatos homeowners have heard about Bay Area Air District rules on gas appliances and worry they'll be forced to get rid of their furnace. They won't. The Air District's appliance rules do not require replacing working equipment. They apply only when an existing furnace or water heater fails or is replaced.
What the rules do change is the future of replacements. Under Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard, which in practice points homeowners toward heat pumps when a furnace is replaced after that date. If your furnace is in good shape overall, a repair can keep it running for years. If it's older and needing frequent fixes, it's worth thinking ahead about a heat pump, especially since the Santa Clara Valley's mild winters suit them well.
For incentives, the federal Energy Efficient Home Improvement Credit (25C) is no longer available for new installations; it covered qualifying heat pumps placed in service before December 31, 2025. You can still check BayREN and your 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 including it in any quote.
Simple Steps to Try Before You Call
Some no-heat calls turn out to have quick fixes. Before scheduling service, check that your thermostat is set to heat, the setpoint is above room temperature, and the batteries aren't dead. Look at the furnace filter and replace it if it's dirty. Make sure the furnace's power switch is on and the breaker hasn't tripped, and that the front panel is fully closed, since many furnaces won't run with the panel loose.
If you smell gas, leave the house and contact your gas utility right away from outside. Don't try to restart the furnace yourself.
