Do you actually come out to Palo Alto, or is that outside your service area?

Yes, Palo Alto is a regular stop for us. Our base is San Ramon, and we cover the Mid-Peninsula as part of our standard Bay Area service area. We schedule Palo Alto calls the same way we schedule any other city, no extra trip fee or minimum added.

Comfortmaker is not a brand I recognize. Is it a decent fit for homes here?

Comfortmaker is made by ICP, which is the Carrier contractor channel, alongside Heil and Tempstar. The equipment is the same platform as Carrier and Bryant, which means the components are well-supported and familiar to any tech who works that family. For Palo Alto specifically, the higher SoftSound furnace models have variable-speed blowers that match well with the milder climate here, where you are running lower fire most of the year. The honest part is that the brand name matters less than the installation quality and whether the equipment was sized correctly for the house.

What does the $75 diagnostic actually include, and what warranty do I get on the repair?

The $75 covers me coming out, running through the system, reading the board fault history, and giving you a specific diagnosis with a written quote for the repair. If you approve the work, the $75 comes off the total. If you decide not to move forward, you pay the $75 for the visit and that is it. Any repair we complete carries a one-year warranty on both parts and labor. On installations the coverage is ten years parts and ten years labor.

Comfortmaker in Palo Alto

Comfortmaker heating and cooling in Palo Alto.

Palo Alto housing runs the full range. The older neighborhoods north of University Avenue and around Crescent Park have mid-century ranch homes with original duct systems that have been serviced and patched for decades. Those houses got Comfortmaker furnaces installed because the price point made sense on a straightforward swap. Closer to the bay, the air carries enough salt moisture that condenser cabinets on outdoor units corrode faster than you'd expect, and I see it consistently on units that are only eight or ten years old. Summers in Palo Alto stay milder than Livermore or Walnut Creek, but the heat comes when it comes, and a heat pump or AC that's been quietly degrading will show you in July.

Comfortmaker shares its control board, igniter, pressure switch, and inducer assembly with Carrier and Bryant. That matters because I read the board faults directly rather than guessing. On a furnace call I pull the fault history off the board first, check the inducer for pressure drop, and test the flame sensor with a microamp meter before I touch anything. On heat pump calls I measure system pressures and check the capacitor and contactor at the condenser. I do not swap parts to find the answer. The diagnosis drives the repair, not the other way around.

This work runs under Bay Area HVAC Service, our HVAC division. The diagnostic is $75 and that fee disappears if you approve the repair. Before any work starts you get a written quote, no surprises on the final bill. We carry EPA Section 608 Universal certification and operate under CSLB license 1136642. Repairs include a one-year parts and labor warranty. On new installations we back the work with a ten-year parts warranty and ten-year labor warranty.

Common repairs we do

What we close on the truck.

Cracked or Failed Hot Surface Igniter. The silicon nitride igniter on Comfortmaker gas furnaces is a common first failure, typically between years four and eight. The board logs a failed ignition fault, the inducer runs, but the burners never light. I confirm the igniter is actually cracked or out of spec with an ohmmeter, then replace it with the correct part rather than a universal substitute. Given how many of these furnaces are tucked into smaller utility spaces in older Palo Alto ranches, clearance matters and the job takes care.
Flame Sensor Carbon Buildup Causing Short-Cycling. A flame sensor caked with oxidation will pull less than one microamp and the board shuts the burners off within a few seconds of ignition. The furnace tries again, fails again, and locks out. I see this regularly on systems in Palo Alto where the furnace only runs a few months a year and the sensor never fully burns clean. I clean or replace the sensor, confirm the microamp reading is back above the board threshold, and verify the lockout clears cleanly.
Condenser Capacitor and Contactor Corrosion. Salt air from the bay makes it to Palo Alto in measurable amounts, and the capacitor and contactor inside the condenser cabinet take the worst of it. A failed run capacitor causes the compressor to draw high amps, run hot, and eventually trip the high-pressure limit. A pitted contactor will stick closed or arc on startup. On a no-cooling or hard-start call I test both components at the unit, check the contactor contacts, and replace what is out of spec. Because the Comfortmaker condenser cabinet shares its layout with Carrier units, access is straightforward.
