Tempstar in Portola Valley
Tempstar heating and cooling in Portola Valley.
Portola Valley sits in the oak-and-redwood hills off Alpine Road and Portola Road, and the housing stock runs from large custom homes on wooded acreage to mid-century modern houses in the Ladera-adjacent pockets and ranch properties out toward Skyline. This is a wildfire-aware community, and PG&E public-safety power shutoffs happen often enough that a lot of homeowners are actively rethinking their heating and cooling strategy around a heat pump plus battery backup rather than a straight gas furnace. Tempstar shows up here less often than Carrier or Lennox, usually where an earlier remodel went the value route on the furnace and condenser. It's built on the same Carrier engineering, just wearing a different name plate.
On a Tempstar diagnosis call, the control board and its stored fault codes are the first thing I check, before I touch anything mechanical. If it's one of the communicating QuietComfort models, the fault log tells me whether a pressure switch is nuisance-tripping or actually failing. Out here I ask early whether the home has generator or battery backup for a shutoff event, because a heat pump that loses power mid-cycle and then restarts cold behaves differently than one that never lost power, and that changes how I read certain fault codes. On the outer roads where a property runs its own well, I also check that the pump and the HVAC system are not fighting for the same backup circuit during an outage.
San Ramon is home base for Bay Area HVAC Service, our HVAC division, and Portola Valley falls on scheduled calls, routed with Hillsborough on our regular Peninsula day, about 50 to 60 minutes down I-680 south and onto CA-92 or I-280, so a booked visit comes with a written arrival time. The diagnostic fee is $99 and we apply it toward the repair if you move forward. You get a written quote before any work starts, no exceptions. Our technicians hold EPA Section 608 Universal certification for refrigerant handling. CSLB license 1136642. Repair work carries a 1-year warranty; new installs carry 10 years on parts and 10 years on labor.
Common repairs we do
What we close on the truck.
- Hot Surface Igniter Failure. A cracked hot surface igniter is the most frequent cause of no-heat calls on Tempstar gas furnaces. Heat gets called for, the inducer starts up, and nothing follows: no ignition, the board locks out after a couple of tries, and the furnace stays cold. Before ordering a part I confirm igniter resistance reads out of spec, then fit the igniter matched to that board revision and check flame establishment and sensor signal before closing things back up.
- Heat Pump Restart Fault After a Power Shutoff. After a PG&E public-safety shutoff, a Tempstar heat pump coming back on generator or battery power sometimes throws a fault it would never show on stable utility power, low voltage at startup tripping a lockout that looks like a compressor problem. I check the actual voltage the unit saw at restart against the board's fault log before I condemn any hard part, because more than once the fix is a voltage or backup-transfer issue, not the heat pump itself.
- Condenser Capacitor and Contactor Wear on the Outdoor Unit. The run capacitor and contactor on Tempstar AC and heat pump condensers are usually the first parts to wear out here, typically somewhere around year five or six. Properties on the ranch lots and outer roads pick up more dust and a wider swing in temperature between a shaded morning and open afternoon sun, and that combination pushes those pull-in points on the contactor to wear early and shortens capacitor life quicker than you would see on a more sheltered install. Rather than wait for either part to quit outright, I check capacitance and contact resistance at every visit, and if one already reads marginal I will quote both together since the labor overlaps.

FAQ
Tempstar in Portola Valley questions, answered.
-
Do you actually come out to Portola Valley, or is that outside your area?
We come out to Portola Valley on scheduled calls, routed with Hillsborough on our regular Peninsula day, about 50 to 60 minutes from San Ramon down I-680 south and onto CA-92 or I-280. We are not a same-day or next-day emergency outfit, but we get you on the schedule fast and you get a written arrival time instead of a guess. -
Does a heat pump make sense here given how often the power goes out?
It is a fair question in a wildfire-aware area with frequent public-safety shutoffs, and the honest answer depends on your backup plan. A heat pump paired with battery or generator backup keeps working through most outages, where a straight gas furnace with an electric-ignition control also needs backup power to run at all, so the shutoff exposure is similar either way unless the whole system is on backup. I will walk through what your specific setup can support at the estimate rather than push one direction. -
What does the $99 diagnostic actually include, and what warranty covers the repair?
The diagnostic covers a full system evaluation: fault code pull, electrical measurements, refrigerant pressures if the system is running, and a written summary of what I found and what it will cost to fix. If you go ahead with the repair, that $99 comes off the invoice. Parts and labor on the repair are backed by a 1-year warranty. For a full system replacement instead of a repair, new installations carry a 10-year commitment on both parts and labor. If a utility or manufacturer rebate applies, I will pin down the exact current figures when I put together your estimate.
