The short answer
PrimeAir HVAC Repair Service fixes furnaces, heat pumps, and wall heaters in Menlo Park homes, with 24/7 emergency service. Bay Area Air District rules do not require you to replace a working furnace, so a repair is often a reasonable choice. If replacement makes more sense, we explain how the 2029 furnace standard and current incentives may affect your decision.
When the heat 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, heat pumps, and wall and floor heaters for homes in the 94025 ZIP code. We come over from our base in Fremont, about 8 miles away across the Bay. We find the cause, explain your options in plain terms, and make the repair once you approve it. Emergency heating service is available 24/7.
Heating Problems We Fix in Menlo Park Homes
Winters on the Peninsula are mild, so many heating systems sit unused for months and then run hard during a cold stretch. That on-and-off pattern tends to expose the same group of problems. Dust settles on burners and sensors, filters get forgotten, and small electrical faults show up the first time the system is asked to run for hours.
These are the issues we see most often:
- Furnace won't ignite, or the igniter glows but the burners never light
- Burners light, then shut off after a few seconds or minutes
- Blower runs but the air from the vents is cool or lukewarm
- System turns on and off frequently without warming the house
- Heat pump blowing lukewarm air, icing up, or stuck in defrost
- Rattling, squealing, booming, or grinding noises when the heat starts
- Thermostat shows a call for heat but nothing happens
- Some rooms stay cold while others overheat
What Happens During a Heating Repair Visit
We start with the basics: thermostat settings and wiring, power to the unit, gas supply, and the condition of the filter. From there we test the parts that commonly fail. On a furnace, that includes the igniter, flame sensor, pressure switch, inducer motor, limit switches, and control board. On a heat pump, it includes the refrigerant charge, reversing valve, defrost controls, capacitors, and outdoor fan.
Because a gas furnace burns fuel inside your home, we also check combustion safety. We look at the heat exchanger for cracks, confirm the vent is drawing properly, and check for carbon monoxide around the unit.
Before any work begins, we explain what we found and what the repair involves, and you decide how to proceed. Many repairs are finished during the same visit. If a part has to be ordered, we tell you, and when it makes sense we get the system running safely in the meantime.
Repair or Replace? What the Air District Rules Mean for You
Many Menlo Park homeowners have asked whether new Bay Area Air District rules force them to give up their gas furnace. They don't. The rules do not require replacing working equipment. They apply only when an existing furnace fails or is replaced. If your furnace can be repaired safely, repairing it is allowed.
The rules do affect what you can buy later. Under the Air District's furnace rule, natural gas furnaces manufactured from 2029 on must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps for replacements after that date. If your furnace is older and needs a major repair, it's worth weighing that timeline before you decide.
On cost, keep in mind that the federal Energy Efficient Home Improvement Credit only covered qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations. BayREN and your local clean energy provider may offer heat pump and electrification incentives, but amounts change by funding cycle. We confirm the current offer before including it in any quote.
Safety First: When to Call Right Away
Some heating problems shouldn't wait until morning. If you smell gas, leave the house first, then call your gas utility or 911 from outside. If a carbon monoxide alarm goes off, get everyone outside and call for help.
Don't keep resetting a furnace that locks itself out, and don't keep running a system that smells like burning wiring. Shut it off at the thermostat and call us. Our 24/7 emergency service covers Menlo Park homes, so you aren't left without heat or with an unsafe system overnight.
