Heating Repair in Redwood City, CA

The short answer

PrecisionFix repairs gas furnaces, heat pumps, and wall furnaces in Redwood City homes, and we offer 24/7 emergency service. Bay Area Air District rules do not require you to replace a working furnace, so repairing sound equipment is often a sensible choice.

When the heat stops working in your Redwood City home, you want a clear answer about what's wrong and what it will take to fix it. PrecisionFix HVAC Repair Service repairs gas furnaces, heat pumps, and wall and floor furnaces in homes across the 94061, 94063, and 94065 ZIP codes. We're based in Palo Alto, about 6 miles southeast, so reaching you is a short drive. Our goal on every visit is to find the actual cause, explain it in plain terms, and get your heat back on. We offer 24/7 emergency service.

Common Heating Problems We Fix in Redwood City Homes

Most heating calls start with a symptom you can see, hear, or feel. Telling us which one you've noticed helps us arrive prepared with the right parts.

Many of these problems trace back to a dirty flame sensor, a failed igniter, a clogged filter restricting airflow, a worn capacitor or blower motor, or a thermostat wiring fault. Others point to something more serious, such as a cracked heat exchanger. If you smell gas, leave the house right away and call your gas utility from outside before you call us.

  • Furnace runs but blows cool or lukewarm air
  • Burners light, then shut off after a few minutes (short cycling)
  • No heat at all, or a thermostat that doesn't respond
  • Banging, squealing, or rattling from the furnace or ductwork
  • Heat pump iced over, stuck in defrost, or relying on backup heat
  • A burning smell that lingers past the first run of the season
  • Uneven heating between rooms, or a blower that won't shut off

What Happens During a Heating Repair Visit

We start by asking what you've noticed and when it began. Then we test the system step by step: thermostat signal, power and safety controls, ignition sequence, burner flame, blower operation, airflow, and venting. On heat pumps we also check the outdoor unit, refrigerant circuit, defrost controls, and backup heat strips.

Before any work begins, we explain what we found and what the repair involves. If a part is failing but not yet broken, we'll point it out so you can decide whether to address it now or keep an eye on it. When the repair is done, we run the system through full heating cycles to confirm it starts, heats, and shuts off the way it should.

Repair or Replace? What Bay Area Air District Rules Mean for You

You may have heard that gas furnaces are being phased out in the Bay Area. Under the Air District's Rule 9-4, natural gas furnaces manufactured starting in 2029 must meet a zero-NOx emission standard. In practice, that steers homeowners toward heat pumps when a furnace is replaced after that date.

The rules do not require you to replace equipment that's working. They apply only when an existing furnace fails or is replaced. If your furnace is in good shape apart from a failed part, repairing it is a reasonable option. If the unit is near the end of its useful life, we'll tell you that too, so you can plan a replacement rather than make a rushed decision on a cold night.

If you're weighing a heat pump, note that the federal Energy Efficient Home Improvement Credit (25C) covered only qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations now. Redwood City homeowners can 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 including it in any quote.

Heat Pump Heating Repair

More Redwood City homes now heat with heat pumps, and they fail differently than furnaces. Common issues include a reversing valve that won't switch into heating mode, a defrost control that leaves the outdoor coil iced over, low refrigerant from a leak, and a failed outdoor fan motor. A heat pump that keeps leaning on its backup electric strips may still feel warm inside while using far more electricity than it should. We diagnose the heat pump itself rather than just resetting it, so the problem doesn't return a week later.

FAQ

Common questions

Don’t see your question? Call (650) 752-4497 and we’ll talk it through.

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

No. The Air District rules don't require replacing working equipment. They apply only when an existing furnace fails or is replaced, and the zero-NOx standard covers furnaces manufactured from 2029 onward.

Is it worth repairing an older furnace?

It depends on the furnace's overall condition and the part that failed. We'll explain what we find so you can weigh a repair against planning a replacement.

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

No. The 25C credit covered qualifying heat pumps placed in service before December 31, 2025. Check BayREN and your local clean energy provider for current incentives; we confirm the current offer before quoting it.

Why does my furnace turn on and then shut off after a few minutes?

Short cycling often comes from a dirty flame sensor, a clogged filter, or an overheating safety switch. Some causes are simple and some need a closer look, so it's worth having it checked.

Yes. We offer 24/7 emergency service in Redwood City and nearby communities including San Carlos, Atherton, Menlo Park, East Palo Alto, and Woodside.
