Heating Repair in Los Gatos, CA

The short answer

SwiftAir Conditioning Repair diagnoses and repairs gas furnaces and heat pumps in Los Gatos homes, including ZIP codes 95030 and 95032. Bay Area Air District rules don't force you to replace a working furnace, so repair is often a reasonable first step. If replacement makes sense, we'll explain your options, including heat pumps.

When the furnace or heat pump 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. SwiftAir Conditioning Repair sends technicians from our San Jose base, about 11 miles north, to homes throughout Los Gatos in the 95030 and 95032 ZIP codes. We repair gas furnaces, heat pumps, and the thermostats, ductwork, and controls that connect them. This page covers the heating problems we see most often, how a repair visit works, and what current Bay Area Air District rules mean if your furnace can't be saved.

Why Los Gatos Heating Systems Act Up

The Santa Clara Valley has a Mediterranean climate with dry summers and mild, damp winters. For a heating system, that means long stretches of sitting idle followed by short bursts of use on chilly mornings and evenings. Dust settles on burners and sensors over the summer, igniters and flame sensors wear from frequent short cycles, and small problems often stay hidden until the first cold snap.

Many homes also have a mix of older furnaces and newer high-efficiency units or heat pumps, and each has its own common failure points. These are the symptoms Los Gatos homeowners call us about most:

  • Furnace clicks or tries to light but shuts off after a few seconds
  • Blower runs but the air from the vents is cool
  • System won't respond to the thermostat at all
  • Heat pump blows lukewarm air or seems stuck in defrost
  • Water pooling near a high-efficiency furnace from a blocked condensate line
  • Rattling, squealing, or banging when the system starts
  • Some rooms stay cold while others overheat

What Happens During a Repair Visit

We start by asking what you've noticed: when the problem began, what it sounds or smells like, and whether it happens every time or only sometimes. That history often points straight to the cause and saves time.

From there, the technician works through the system in a logical order and explains what they find before doing any work.

  • Check the thermostat, power, and settings to rule out simple causes
  • Inspect the filter, igniter, flame sensor, and burners on gas furnaces
  • Test safety switches, the blower motor, and the control board
  • On heat pumps, check refrigerant operation, the reversing valve, and defrost controls
  • Look for airflow problems in accessible ducts and vents
  • Walk you through the findings and your repair options before starting

Repair or Replace? What the Air District Rules Mean

You may have heard that Bay Area gas furnaces are being phased out. Here's what the Bay Area Air District rules actually do. They do not require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced. If your furnace can be repaired safely and sensibly, repairing it is allowed.

Under Rule 9-4, 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 aging and needs frequent repairs, it can make sense to plan the next step now instead of during an emergency.

The rule for small water heaters, Rule 9-6, set a zero-NOx date of 2027. The Air District Board is considering amendments in November 2026 that could delay it, so check the current rule before planning a water heater replacement.

If You're Considering a Heat Pump

A heat pump heats in winter and cools in summer. That matters because inland and southern parts of the valley run noticeably hotter in summer than areas near the Bay. For homes without central air, one system can handle both seasons.

On incentives, note that the federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date. 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 quoting it.

What to expect

How a visit goes

  1. Clear answers before work begins

    We show you what's wrong, explain your options, and let you decide. Work starts after you approve it.

  2. Repair first when it's reasonable

    Not every problem calls for new equipment. If a repair will keep your system running well, we'll recommend that instead of a replacement.

  3. Equipment that fits your home

    When you do need a new system, we size it for your home, your ductwork, and how hot your part of the valley gets. We don't simply match the old unit's label.

FAQ

Common questions

Do Air District rules require me to replace my working gas furnace?

No. The Bay Area Air District appliance rules do not require replacing working equipment. They apply only when an existing furnace or water heater fails or is replaced.

Do you repair heat pumps as well as gas furnaces?

Yes. We diagnose and repair both gas furnaces and heat pumps in Los Gatos homes, along with the thermostats, controls, and ductwork connected to them.

My furnace smells like burning when it first turns on. Is that normal?

A light dusty smell for a few minutes after the first use of the season is common, because dust burns off the burners. If the smell lasts, smells electrical, or you smell gas, turn the system off. For any gas smell, leave the house and contact your gas utility or emergency services.

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

No. The federal 25C credit covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date. Check BayREN and your local clean energy provider for current incentives.

How do I know whether to repair or replace my furnace?

We look at the furnace's condition, how often it has needed repairs, and the cost of the specific fix. Then we explain your options. Keep in mind that gas furnaces manufactured from 2029 must meet a zero-NOx standard, which points most future replacements toward heat pumps.
