Furnace problems we commonly diagnose in Los Gatos homes
Santa Clara Valley winters are mild but damp. Many furnaces sit idle for months and then run hard during cold snaps, and that on-and-off pattern tends to expose weak parts all at once. These are the problems we handle most often:
Some symptoms point to more than one cause. A furnace that shuts off early, for example, may have a dirty flame sensor. It could also have a clogged filter that makes it overheat, or a venting problem that trips a pressure switch. Testing each possibility is how we avoid replacing parts that weren't the problem.
- Furnace runs but blows cool air, often from a failed igniter, dirty flame sensor, or gas valve issue
- Burners light and then shut off after a few seconds
- Blower won't start, or runs constantly and won't stop
- Short cycling, where the furnace turns on and off every few minutes
- Loud banging, squealing, or rattling at startup
- Error codes flashing on the control board
- Weak airflow in some rooms while others get too warm
- Thermostat calls for heat but nothing happens
What happens during a furnace repair visit
Our technician starts by asking what you noticed: when the problem started, any sounds or smells, and whether it happens every cycle or only sometimes. Then we check the system in order. That means the thermostat and power first, then ignition, burners, flame sensing, safety switches, blower, and venting.
Safety comes first with any gas appliance. We inspect the flue and venting, look for signs of heat exchanger damage, and check for gas leaks around the connections we work on. If we find a condition that makes the furnace unsafe to run, we won't just restart it and leave. We'll explain exactly what we found and why it matters.
Before any repair, you get a clear explanation of the problem and your options. Many common failures can often be fixed in the same visit, including igniters, flame sensors, capacitors, and pressure switches.
Repair or replace? What current Bay Area rules mean for you
If your furnace is older, it's reasonable to wonder whether a repair is worth it. One point that often gets confused: the Bay Area Air District appliance rules do not require you to replace a furnace that still works. They apply only when an existing furnace fails or is replaced.
The timeline still matters for planning. Under the Air District's furnace rule, natural gas furnaces manufactured from 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 near the end of its life, it's worth considering whether your next system will be a heat pump.
The federal Energy Efficient Home Improvement Credit only covered qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations. Bay Area homeowners can still 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 discussing it in any quote.
We'll give you an honest read on your furnace's condition. Then you can decide whether a repair makes sense now or it's time to plan ahead.
Simple steps to keep your furnace ready for winter
A few habits lower the chance of a no-heat problem during the first cold week of the season:
If you smell gas, leave the house right away. Call your gas utility or 911 from outside before calling us.
- Check or replace the air filter before heating season, and every one to three months while the furnace is in use
- Keep supply and return vents clear of furniture, rugs, and stored items
- Give the furnace a test run in early fall, before you actually need it
- Keep the area around the furnace clear, especially in garages and closets
- Make sure carbon monoxide alarms work and have fresh batteries
- Schedule a tune-up so small problems get caught early
