Do you actually come out to Daly City, or do you just cover San Francisco proper?

Daly City is a regular stop on our Peninsula route, and we cover Brisbane the same way since it sits right next door off Bayshore Boulevard. We have a technician based in San Mateo County now, which puts North Peninsula calls like yours within easy reach instead of routing someone out from San Ramon. We do not promise same-day service, but response times here are usually quick. Call (925) 999-4095 and we will get you a window.

Is Tempstar a decent brand, or should I be replacing it with something else once it fails?

Tempstar is built on the same ICP platform as Heil and Comfortmaker, and that platform shares engineering with Carrier. The compressor, heat exchanger, and control board are the same tier of hardware, just sold under a different badge through independent contractors instead of a large dealer network. For a Daly City home that needs a furnace able to handle running most of the year, Tempstar holds up fine. We are not a factory dealer for the brand, we are an independent shop that services it regularly and knows where it tends to wear.

What does the $99 diagnostic actually get me?

You get a real diagnostic: fault codes off the board, electrical readings, a check of the venting and pressure switch operation, and a written quote with the specific repair and the price. If you approve the work that same visit, the $99 comes off your invoice instead of stacking on top. We stand behind the parts and labor we install with our own warranty, and I will walk you through exactly what that covers before we start.

Tempstar Heat Pump, AC & Furnace Repair · Daly City, CA

Tempstar furnace and heat pump repair in Daly City, where the marine layer sitting over the Westlake tract homes keeps the heat cycling long after sunnier parts of the Peninsula have shut theirs off.

Tempstar in Daly City

Tempstar in Daly City kitchens.

Daly City runs cool and gray most of the year, and the fog that rolls in over Westlake and Serramonte does more to shape how an HVAC system works here than anything else on the Peninsula. The Doelger-built tract homes from the 1950s and 60s that fill most of Daly City came with small furnace closets and ductwork sized for a mild climate, not for units that run six or eight months a year the way they do here. A lot of that original equipment has been replaced with Tempstar systems over the decades, usually installed by a local contractor rather than a large dealer chain.

When I get a Tempstar call in Daly City, I start at the control board and pull the fault history before I open anything up. Tempstar shares its engineering with Heil and Comfortmaker under the ICP umbrella, so the board logic and wiring layout stay consistent across all three, which speeds up the diagnostic. Because the furnace runs so much of the year here, I pay close attention to the parts that wear from cycle count rather than heat load: the igniter, the pressure switch, the inducer bearings.

We cover Daly City, San Bruno, Pacifica, and South San Francisco on our regular Peninsula route, and we treat Brisbane the same way since it sits a short hop off Bayshore Boulevard and we get calls there often. Bay Area HVAC Service is the HVAC side of the Adrium Service Solutions family, licensed under CSLB #1136642, and our technicians carry EPA Section 608 Universal certification for anything involving refrigerant. The diagnostic is a flat $99, waived if you approve the repair on the same visit, and you get the price in writing before any work starts. We are out here seven days a week.

Common repairs we do

What we close on the truck.

Hot Surface Igniter Wear from Extended Heating Seasons. A furnace that runs most of the year works its igniter far harder than one that only kicks on for a few cold snaps. The silicon nitride igniter used on Tempstar 80 and 90-plus percent furnaces is not built for infinite cycles, and in a Daly City home where the heat runs from October through May, I see them fail two or three years sooner than in warmer parts of the Bay. The furnace calls for heat, the inducer spins, but the burners never catch and the board locks out. I check current draw on the igniter circuit before replacing it, since a marginal transformer or a loose connection can mimic the same symptom.
Pressure Switch and Condensate Line Clogging from Constant Moisture. The persistent damp air here means condensate lines and the pressure switch tubing on Tempstar furnaces collect more buildup than they would in a drier climate. When the drain trap partially clogs, the pressure switch cannot pull the vacuum it needs to prove airflow, and the furnace shuts down before ignition with a fault code that looks like a bad switch but usually is not. I clear the line, check the switch itself with a manometer, and confirm the inducer is pulling the draft it should before I call the switch bad and replace it.
Draft Inducer Motor Bearing Failure on High-Cycle Furnaces. The draft inducer motor on a Tempstar furnace spins up every single heat cycle, and in a house where the furnace runs almost daily for most of the year, that adds up fast. Worn bearings show up first as a rattling or grinding sound at startup, then as a motor that draws high current and eventually trips its internal overload. I test amperage draw against the nameplate rating and check the wheel for cracking before condemning the motor, since a loose inducer wheel can throw the same noise.
