Heating Repair in Los Gatos, CA

The short answer

CoolVantage HVAC Service repairs gas furnaces, heat pumps, thermostats, and ductwork for Los Gatos homes in 95030 and 95032. We diagnose the cause and explain your options before any work begins. You can keep repairing a working gas furnace, because Bay Area air rules apply only when a furnace fails or is replaced.

When the furnace quits on a cold, damp Los Gatos night, you want a clear answer about what's wrong and what it will take to fix it. CoolVantage HVAC Service repairs gas furnaces, heat pumps, and the controls and ductwork that connect them for homes across Los Gatos, in ZIP codes 95030 and 95032. We're based in San Jose, about 6 miles northeast, so getting to you is a short drive. Our goal on every call is the same: find the actual cause, explain it in plain terms, and let you decide what to do next.

Heating problems we commonly fix in Los Gatos

Santa Clara Valley winters are mild but damp, and many Los Gatos homes go months without running the heat. During that idle stretch, parts dry out, dust settles on burners, and small problems stay hidden until the first cold week. These are the issues homeowners call us about most:

If you smell gas, leave the house and call your gas utility or 911 from outside before calling any HVAC company.

  • Furnace runs but blows cool or lukewarm air
  • Igniter or flame sensor failures that let the burner light and then shut off
  • Short cycling, where the system turns on and off every few minutes
  • Heat pumps that ice up, get stuck in defrost, or won't switch into heating mode
  • Thermostats that lose settings, read the wrong temperature, or don't call for heat
  • Uneven heat between floors or rooms, often from leaky or disconnected ducts
  • Banging, squealing, or rattling from the blower or burner area
  • A burning smell that lingers past the first few minutes of the season

What to expect on a heating repair visit

Our technician starts by asking what you've noticed. When did the problem start? Is it constant, or does it come and go? Have you heard any sounds or noticed any smells? Then we check the system step by step, including the thermostat, power and gas supply, ignition sequence, flame sensor, pressure switches, blower motor, filter, and venting. On heat pumps we also check refrigerant pressures, the reversing valve, and the outdoor coil.

Before any repair work, we tell you what we found, what we recommend, and what your options are. Sometimes the fix is a dirty flame sensor or a clogged filter. Sometimes it's a failed control board or motor. Either way, you get the facts first and the decision stays with you.

While the system is open, we also look for safety concerns such as a cracked heat exchanger, poor venting, or signs of carbon monoxide risk. We'll point out anything that needs attention.

Repair or replace: what Bay Area air rules mean for you

Many Los Gatos homeowners ask whether the Bay Area Air District rules mean they have to get rid of their gas furnace. They don't. The appliance rules apply only when an existing furnace fails or is replaced. A working furnace can stay in service, and repairing it is still an option.

What changes is the replacement picture. 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 older and needs frequent repairs, keep that timeline in mind when you compare fixing it against replacing it.

If a heat pump makes sense for your home, note that the federal Energy Efficient Home Improvement Credit covered only qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations now. Local programs through BayREN and your clean energy provider may offer electrification incentives, but amounts and availability change by funding cycle. We confirm the current offer before we quote it.

FAQ

Common questions

Don’t see your question? Call (669) 345-5610 and we’ll talk it through.

Do I have to replace my gas furnace because of Bay Area air rules?

No. The Air District appliance rules don't require replacing working equipment. They apply only when an existing furnace fails or is replaced, so repairing a working furnace is still allowed.

Why does my furnace smell like it's burning when I first turn it on?

Dust that settled on the burners and heat exchanger during the warm months burns off in the first few minutes. If the smell lasts longer than that, or smells like gas or melting plastic, turn the system off and have it checked.

My heat pump has ice on the outdoor unit. Is that a problem?

A light frost that clears during a defrost cycle is normal. Heavy ice that stays, or a unit that never seems to finish defrosting, can point to airflow, sensor, refrigerant, or control problems that need a technician.

Should I repair or replace an older furnace?

It depends on the furnace's condition, how often it needs repairs, and any safety issues we find. Keep in mind that gas furnaces manufactured from 2029 must meet a zero-NOx standard, which points most future replacements toward heat pumps. We'll lay out the options so you can decide.

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

No. The federal Energy Efficient Home Improvement Credit covered qualifying heat pumps placed in service before December 31, 2025. You can check BayREN and your local clean energy provider for current incentives, which change by funding cycle.

Do you serve both Los Gatos ZIP codes?

Yes. We provide heating repair throughout 95030 and 95032, as well as in nearby Monte Sereno, Campbell, Saratoga, Cupertino, and Santa Clara.
