The short answer

ArcticPoint HVAC Repair fixes furnaces, heat pumps, and wall heaters in Cupertino homes, with 24/7 emergency service. Bay Area Air District rules don't force you to replace a working furnace, so repair is still an option, and we'll give you an honest read on whether it makes sense for your system.

When the heat quits on a cold, damp Cupertino night, you want a clear answer about what's wrong and what it will take to fix it. ArcticPoint HVAC Repair diagnoses and repairs gas furnaces, heat pumps, and wall and floor heaters in homes across Cupertino's 95014 ZIP code. We come from our base in San Jose, about 16 miles away, and we offer 24/7 emergency service when a breakdown can't wait until morning.

Heating Problems We See in Cupertino Homes

The Santa Clara Valley has mild but damp winters, so many Cupertino furnaces sit idle for months and then run hard through a few cold weeks. That on-and-off pattern shows up in the problems we're called about most often:

  • A furnace that won't ignite, or lights and then shuts off, often from a dirty flame sensor or failed igniter
  • A blower that runs but pushes cool air, which points to a gas supply, ignition, or limit switch problem
  • Short cycling, frequently caused by a clogged filter or a system that overheats
  • Banging, squealing, or rattling from the burners, blower motor, or loose panels
  • A heat pump stuck in defrost, blowing lukewarm air, or iced over on a damp morning
  • Uneven rooms, which in older homes can trace back to leaky or disconnected ductwork
  • A thermostat that reads wrong or won't call for heat

What Happens During a Repair Visit

A technician starts by asking what you've noticed: when the problem began, any sounds or smells, and whether it happens every cycle or only sometimes. Then we check the system the way it actually runs, from the thermostat call through ignition, airflow, and shutdown.

For gas furnaces, that includes inspecting the burners, flame sensor, igniter, pressure switches, and venting, and checking for carbon monoxide and gas leaks. For heat pumps, we look at refrigerant pressures, the reversing valve, defrost controls, and the outdoor coil. Before any work begins, we explain what we found, what the repair involves, and whether a part needs to be ordered.

If something looks unsafe, such as a cracked heat exchanger or a venting problem, we'll tell you plainly and shut the unit down rather than leave it running.

Repair or Replace Under Bay Area Air District Rules

Many homeowners have heard about the Bay Area Air District's appliance rules and worry they'll be forced to give up a working furnace. They won't. The rules don't require replacing working equipment. They apply only when an existing furnace fails or is replaced, so repairing your current furnace is still an option.

What changes is the long-term picture. Starting in 2029, natural gas furnaces manufactured under the Air District's furnace rule 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 repairs are becoming more frequent, keep this in mind when you weigh one more fix against planning a replacement. We'll give you an honest assessment of your system's condition so you can decide on your own timeline.

Heat Pump Repair and Current Incentives

More Cupertino homes now heat with heat pumps, and we repair those too. Valley winters rarely get very cold, so a properly working heat pump handles most nights easily. Weak heat usually signals a fixable issue, such as low refrigerant, a failing sensor, or a defrost fault.

If you're considering a switch to a heat pump instead of repairing an older furnace, note that the federal Energy Efficient Home Improvement Credit (25C) only covered qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations after that date. Local help may still exist, so check BayREN and your local clean energy provider for current heat pump and electrification incentives. Amounts and availability change by funding cycle, and we confirm the current offer before quoting it.

FAQ

Common questions

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

No. The Air District's appliance rules don't require replacing working equipment. They apply only when an existing furnace fails or is replaced, so you can keep repairing a furnace that's in good shape.

What changes for furnaces in 2029?

Starting in 2029, natural gas furnaces manufactured under the Air District rule must meet a zero-NOx emission standard. In practice, that steers homeowners toward heat pumps when they replace a furnace after that date.

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

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

Do you offer emergency heating repair in Cupertino?

Yes. We offer 24/7 emergency service in Cupertino and nearby cities. If you smell gas, leave the house and contact your gas utility or 911 before calling us.

Why does my furnace struggle on the first cold night of the season?

After a long, dry summer, dust often builds up on the flame sensor, burners, and filter. A clogged filter or dirty sensor can cause short cycling or a furnace that lights and then shuts off. These are usually straightforward fixes.

Do you repair heat pumps as well as furnaces?

Yes. We repair heat pumps, gas furnaces, and wall and floor heaters, including problems with refrigerant, defrost controls, reversing valves, and thermostats.
