The short answer

We diagnose the problem, explain what we found in plain terms, and lay out your options before any work begins.

Common Heating Problems in Campbell Homes

The Santa Clara Valley has dry summers and mild, damp winters, so many Campbell furnaces and heat pumps sit unused for months. When the first cold night arrives, problems that built up quietly over the off-season tend to show up all at once. Dust settles on burners and sensors, filters clog, and small electrical issues that went unnoticed in summer can keep a system from starting.

Because winters here are mild, it's easy to put off a heating problem and get by with a space heater. But damp air and chilly nights still make a home uncomfortable, and a furnace that short-cycles or a heat pump that struggles uses more energy than it should. Call us if you notice any of these signs:

  • The system runs but blows cool or lukewarm air
  • The furnace starts, shuts off quickly, and repeats
  • A burning-dust smell that lasts beyond the first few minutes of the season
  • Banging, squealing, rattling or grinding noises
  • Some rooms stay noticeably colder than others
  • The thermostat doesn't respond or the system won't turn on
  • A heat pump that frosts over and doesn't clear, or runs constantly

What Happens During a Heating Repair Visit

Our technician starts by asking what you've noticed: when the problem started, what it sounds or smells like, and whether it's constant or comes and goes. Then we check the system step by step, including the thermostat, power and controls, filter and airflow, ignition and flame sensing on gas furnaces, and refrigerant and defrost operation on heat pumps.

Once we know the cause, we explain it and describe the repair before doing anything. If there's more than one reasonable option, we'll walk you through the tradeoffs. If we find a safety concern, such as signs of a cracked heat exchanger or a gas issue, we'll tell you directly and explain what needs to happen next.

Furnaces, Heat Pumps and Other Systems We Repair

Campbell has a mix of older single-story homes, newer builds and remodels, so we see a wide range of heating equipment. We repair gas forced-air furnaces, heat pumps (both ducted and ductless mini-splits), and the thermostats, blower motors, igniters, control boards and ductwork connected to them.

Some homes have an older furnace paired with newer air conditioning, or a heat pump added during a remodel. We look at how the whole system works together, since a heating problem sometimes comes from ductwork, airflow or controls rather than the furnace or heat pump itself.

Repair or Replace? What Bay Area Rules Mean for You

Many Campbell homeowners ask whether new Bay Area Air District rules mean they have to get rid of their gas furnace. They don't. The Air District's appliance rules don't require replacing working equipment. They apply only when an existing furnace or water heater fails or is replaced. If your furnace can be repaired safely and reasonably, repair is still a valid choice.

Looking further ahead, Rule 9-4 requires natural gas furnaces manufactured from 2029 on to 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, it can be worth thinking about that timeline now rather than during an emergency.

If you're considering a heat pump, keep in mind that the federal 25C tax credit only 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 heat pump incentives. Amounts and availability change by funding cycle, so we confirm the current offer before including it in any quote.

FAQ

Common questions

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

After months of sitting idle, dust collects on the burners and heat exchanger. A burning-dust smell for the first few minutes is common. If it lasts longer, smells like electrical burning, or you smell gas, turn the system off and contact us.

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

No. The rules don't require replacing working equipment. They apply only when a furnace fails or is replaced. A furnace that can be safely repaired can stay in service.

Should I repair my older furnace or switch to a heat pump?

It depends on the furnace's condition, how often it needs repairs, and your plans for the home. Gas furnaces manufactured from 2029 must meet a zero-NOx standard, so many homeowners replacing a furnace will be looking at heat pumps. We'll give you an honest assessment of both paths.

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

The federal 25C credit covered qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations after that date. Check BayREN and your local clean energy provider for current incentives.

Do you repair ductless mini-split heat pumps?

Yes. We repair both ducted heat pumps and ductless mini-split systems, along with thermostats and controls.

Do you serve areas near Campbell?

Yes. Along with Campbell, we serve Monte Sereno, Los Gatos, Saratoga, Cupertino and Santa Clara from our base in San Jose.
