Heating Repair in Los Gatos, CA

The short answer

ComfortFlow repairs furnaces, heat pumps, thermostats, and ductwork for Los Gatos homes in ZIP codes 95030 and 95032. We find the actual cause, explain your options before any work starts, and tell you honestly whether repair or replacement makes more sense. Bay Area Air District rules do not require you to replace working equipment.

When the furnace won't light on a cold morning in Los Gatos, you want a clear answer about what's wrong and what it will take to fix it. ComfortFlow HVAC Contractor repairs gas furnaces, heat pumps, and the ductwork and controls that connect them for homes throughout Los Gatos (95030 and 95032). We drive about 12 miles from our San Jose base, so we know South Bay homes. We also give straight advice on whether a repair makes sense, given the Bay Area's changing appliance rules.

Heating problems we see in Los Gatos homes

The Santa Clara Valley has mild, damp winters, so many Los Gatos heating systems sit idle for months and then run hard when the first cold snap arrives. Dust, worn parts, and weak components that went unnoticed all summer tend to show up in that first week of real use.

Homes near the foot of the Santa Cruz Mountains can see cooler nights than the valley floor. That puts a steady load on the furnace or heat pump through the evening and early morning. Here are the calls we get most often:

  • Furnace runs but blows cool or lukewarm air
  • Igniter or flame sensor failures that keep the burners from staying lit
  • Short cycling, where the system turns on and off every few minutes
  • Heat pumps stuck in defrost or not switching into heating mode
  • Thermostats that lose settings or don't call for heat
  • Uneven rooms caused by leaky, crushed, or disconnected ducts
  • Burning, musty, or unusual smells at startup

What happens during a heating repair visit

We start by asking what you've noticed, such as noises, smells, error codes, or rooms that never warm up. Then we check the system from the thermostat through the burners or compressor, the blower, the filter, and the venting. On gas furnaces we look at ignition, flame quality, and safety switches. We also check that combustion gases are venting properly.

Once we find the cause, we explain it in plain terms and lay out your options before doing any work. If a part has to be ordered, we tell you, and when it's safe to do so we can help you keep some heat going in the meantime. We don't recommend replacing equipment that can be reasonably repaired.

Repair or replace: what Bay Area rules mean for you

Many Los Gatos homeowners have heard that gas furnaces are being phased out. Under Bay Area Air District 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. The rules do not require you to replace a furnace that still works. They apply only when existing equipment fails or is replaced.

So if your furnace has a fixable problem, repairing it is a perfectly reasonable choice. If your system is older and needs major repairs, it may be worth comparing the repair against a heat pump. We'll walk through both honestly.

On incentives, the federal 25C tax credit for heat pumps covered only systems placed in service before December 31, 2025, so it does not apply to new installations. You can still check BayREN and your local clean energy provider for current heat pump and electrification incentives. Those amounts change by funding cycle, so we confirm the current offer before including it in any quote.

Heat pump and dual-system repair

More Los Gatos homes now heat with heat pumps, either alone or alongside a gas furnace. We repair reversing valves, defrost controls, refrigerant leaks, outdoor fan motors, and the control boards that coordinate the two systems in a dual-fuel setup. A heat pump that runs constantly or can't keep the house warm on a cold night usually has a specific, findable cause, and we track it down rather than guess.

FAQ

Common questions

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

No. The Air District rules do not require replacing working equipment. They apply only when a furnace fails or is replaced. A repairable furnace can be repaired.

Why does my furnace smell like burning the first time I turn it on?

Dust that settles on the heat exchanger over the summer often burns off for a few minutes at startup. If the smell lingers, smells like gas, or seems electrical, shut the system off and call for service.

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. Check BayREN and your local clean energy provider for current incentives.

My heat pump is blowing cool air in winter. Is it broken?

Not always. Heat pumps briefly run a defrost cycle that can feel cool. If it happens constantly or the house won't warm up, something like a reversing valve, sensor, or refrigerant problem may need repair.

Which Los Gatos ZIP codes do you serve?

We serve all of Los Gatos, including 95030 and 95032, plus nearby Monte Sereno, Campbell, Saratoga, Cupertino, and Santa Clara.

How do I know whether to repair or replace my heating system?

We look at the condition of the equipment, the cost and scope of the repair, and how well the system heats your home. Then we give you both options plainly so you can decide.
