Furnace Repair in Menlo Park, CA

The short answer

PrimeAir HVAC Repair Service repairs gas furnaces in Menlo Park homes. We diagnose problems like no heat, short cycling and ignition failures before replacing any parts. We offer 24/7 emergency service, and Bay Area Air District rules do not require you to replace a furnace that still works.

When a furnace quits on a cold, damp Menlo Park night, you want a clear answer about what's wrong and what it will take to fix it. PrimeAir HVAC Repair Service repairs gas furnaces in homes throughout Menlo Park (94025), from the first sign of trouble through a full safety check. We come over from our base in Fremont, about 8 miles northeast, and we offer 24/7 emergency service for no-heat calls and safety concerns. Below is what we look for, how a repair visit works, and how current Bay Area rules affect your choices if your furnace is getting older.

Furnace problems we see in Menlo Park homes

Many furnaces here sit idle for much of the year, then run hard during stretches of chilly weather. Because of that on-and-off pattern, problems often show up the first time the heat comes on in fall. Dust settles on burners and sensors, filters get forgotten, and small parts that worked fine last winter can fail at startup.

Some of these are simple fixes. Others point to a failing inducer motor, control board, igniter or limit switch. We test before we replace anything, so you aren't paying for parts you don't need.

  • Furnace runs but blows cool or lukewarm air
  • Burners light, then shut off after a few seconds, often caused by a dirty flame sensor
  • No ignition at all, or repeated clicking without a flame
  • Blower runs constantly or won't come on
  • Short cycling, where the furnace turns on and off every few minutes
  • Banging, squealing or rattling from the cabinet or ducts
  • Uneven heat between rooms or floors
  • A thermostat that doesn't seem to control the furnace

What happens during a furnace repair visit

We start by asking what you've noticed: when the problem started, any sounds or smells, and whether it happens constantly or comes and goes. Then we check the thermostat, filter, gas supply, ignition sequence, flame sensor, safety switches, blower and venting.

Once we find the cause, we explain it in plain terms and walk you through your options before any work begins. Many repairs can be finished on the first visit. If a part has to be ordered, we'll tell you how long it should take and whether the furnace can run safely in the meantime.

We also look at combustion and venting on every gas furnace call. A cracked heat exchanger or blocked flue can let carbon monoxide into the home, and you want problems like those found early.

Repair or replace? What Bay Area rules mean for you

Bay Area Air District appliance rules do not require you to replace a furnace that's working. They apply only when an existing furnace fails or is replaced. If your furnace can be repaired safely and reasonably, repair is still a normal choice.

Looking ahead, gas furnaces manufactured from 2029 must meet a zero-NOx emission standard under the Air District's Rule 9-4. 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 make sense to plan for that change now instead of during a no-heat 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. It is not available for new installations after that date. Local incentives may still help. BayREN and your local clean energy provider run programs that change by funding cycle, so we confirm what's currently offered before including it in any quote.

When to call right away

Some furnace problems shouldn't wait for a convenient appointment. PrimeAir offers 24/7 emergency service for Menlo Park homes. If you smell gas, leave the house first and call your gas utility or 911 from outside before calling us.

  • You smell gas near the furnace or anywhere in the house
  • Your carbon monoxide alarm goes off
  • You see scorch marks, melted wiring or soot around the furnace
  • The furnace trips a breaker repeatedly
  • You have no heat and someone in the home is elderly, very young or ill

FAQ

Common questions

How do I know if my furnace needs a repair or just a new filter?

Start by replacing a dirty filter and checking that the thermostat is set to heat. If the furnace still won't light, shuts off quickly, blows cool air or makes unusual noises, it's time for a technician to diagnose it.

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

A common cause is a dirty or failing flame sensor, which shuts the gas off when it can't confirm a flame. Overheating from a clogged filter, a faulty limit switch or a venting problem can cause the same symptom. We test each of these to find the actual cause.

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

No. Bay Area Air District appliance rules don't require replacing working equipment. They apply only when a furnace fails or is replaced. Starting in 2029, newly manufactured gas furnaces must meet a zero-NOx standard, which points most replacements after that date toward heat pumps.

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, and it isn't available for new installations after that date. You can check BayREN and your local clean energy provider for current incentives. We confirm what's available before quoting it.

Do you offer emergency furnace repair in Menlo Park?

Yes. PrimeAir HVAC Repair Service offers 24/7 emergency service in Menlo Park and nearby cities, including East Palo Alto, Atherton and Redwood City.

What should I do if I smell gas near my furnace?

Leave the house right away. Don't flip switches or use anything that could spark. From outside, call your gas utility or 911. Once the gas leak is addressed, we can inspect and repair the furnace.
