When the furnace quits on a cold, damp Monte Sereno night, you want to know what failed and what it will take to fix it. Prime Choice HVAC Repair Service drives about 7 miles from our San Jose base to diagnose and repair gas furnaces, heat pumps, and wall heaters in Monte Sereno homes. We explain what we find in plain terms and go over your repair options before any work starts. We'll also tell you honestly whether a repair makes sense for your system.

Why Heaters Act Up in Monte Sereno Homes

The Santa Clara Valley has a Mediterranean climate, with dry summers and mild, damp winters. For most Monte Sereno households, that means the heater sits unused for months. Then it gets switched on all at once when chilly fall evenings arrive. Many heating problems show up during that first week of real use.

Months of idle time let dust settle on burners and flame sensors. A filter that was fine in spring can be clogged by fall. Damp winter air can also wear on metal parts and electrical connections over time. Older homes may still rely on original ductwork or wall furnaces that have seen years of on-and-off use, and those systems tend to wear out in predictable places.

Heating Problems We Diagnose and Repair

We work on gas furnaces, heat pumps, and gas wall heaters. These are common problems we find and fix:

  • Furnace runs but blows cool or lukewarm air
  • Burners light and then shut off after a few seconds, often because of a dirty or failing flame sensor
  • Igniter or pilot problems that keep the system from starting
  • Blower motor that won't run, hums, or makes grinding or squealing noises
  • Thermostat that doesn't call for heat or reads the wrong temperature
  • Heat pump that is iced over, stuck in defrost, or won't switch into heating mode
  • Short cycling, where the system turns on and off too often
  • Tripped limit switches caused by restricted airflow or clogged filters
  • Uneven heating from room to room, sometimes caused by leaky or disconnected ducts
  • Gas or burning smells, or a carbon monoxide alarm: leave the house and call your gas utility or 911 first, and we can repair the equipment once it's safe

What Happens During a Repair Visit

Our technician starts by asking what you've noticed. That includes when the problem began, any sounds or smells, and whether it happens every cycle or only sometimes. Then we test the system in order: thermostat, power, ignition, gas supply, flame, airflow, and safety controls. That way we fix the cause, not just the symptom.

Before any work begins, we explain what failed, what the repair involves, and your options. We carry common parts like igniters, flame sensors, capacitors, and thermostats, so many repairs can be finished on the first visit. If a part has to be ordered, we tell you how long it should take. We also make sure the system is left in a safe condition until we return.

Repair or Replace? What Bay Area Rules Mean for You

Most heating problems are worth repairing. If your furnace is aging and needs a major part, though, it's fair to ask whether replacement makes more sense. We'll give you our honest read on the system's condition and leave the decision to you.

Bay Area Air District rules often come up in these conversations. The rules don't require you to replace working equipment. They apply only when a furnace or water heater fails or is replaced. Under Rule 9-4, gas furnaces manufactured from 2029 on must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps for furnace replacements after that date. Keeping a working furnace in good repair is fully within the rules.

If you're thinking about a heat pump, note that the federal 25C tax credit only covered systems placed in service before December 31, 2025. It doesn't apply to new installations. BayREN and your local clean energy provider may offer heat pump or electrification incentives, but amounts and availability change by funding cycle. We confirm the current offer before including it in any quote.

FAQ

Common questions

Don’t see your question? Call (669) 274-2438 and we’ll talk it through.

Do you repair heating systems in Monte Sereno?

Yes. We repair gas furnaces, heat pumps, and gas wall heaters in Monte Sereno, about 7 miles southwest of our San Jose base. We also serve Los Gatos, Saratoga, Campbell, Cupertino, and Santa Clara.

Why does my furnace start and then shut off after a few seconds?

A common cause is a dirty or failing flame sensor. The furnace can't confirm the burners are lit, so it shuts the gas off for safety. Restricted airflow, a clogged filter, or a faulty limit switch can cause similar shutdowns. We test each of these to find the real cause.

Do I have to replace my gas furnace because of the Air District rules?

No. The Bay Area Air District rules don't require replacing working equipment. They apply only when a furnace fails or is replaced. Gas furnaces manufactured from 2029 on must meet a zero-NOx standard, which mainly affects what you'd choose for a replacement after that date.

Can I still get a federal tax credit for a heat pump?

The federal 25C credit covered qualifying heat pumps placed in service before December 31, 2025, so it isn't available for new installations. You can check BayREN and your local clean energy provider for current incentives. We confirm what's available before quoting it.

What can I check before calling for heating repair?

Make sure the thermostat is set to heat and has fresh batteries if it uses them. Check that the filter isn't clogged and the furnace breaker hasn't tripped. Also confirm the furnace access panel is closed securely, since many furnaces won't run with the door switch open.

What should I do if I smell gas near my heater?

Leave the house right away and call your gas utility or 911 from outside. Don't flip switches or try to relight anything. Once the utility has made the area safe, we can diagnose and repair the heating equipment.
