Tempstar in Martinez
Tempstar heating and cooling in Martinez.
Martinez sits at the north end of the Diablo Valley, close enough to the Carquinez Strait that outdoor units on the west side of town pick up salt-laden air off the water. That corrosion load on condenser coils and cabinet seams is real and it shortens contactor and capacitor life faster than you see in Walnut Creek or Danville. The housing mix runs from pre-war craftsmans downtown near the waterfront to mid-century ranch tracts further inland toward Alhambra Valley Road. The older downtown stock often has no existing ductwork, so a Tempstar ductless or mini-split install makes sense there. The ranch tracts have central ducted systems, and that is where most of the furnace and AC condenser work comes from.
We start every Tempstar job by pulling fault codes off the control board before we touch anything. Tempstar uses the same ICP platform as Heil and Comfortmaker, so the board logic and the part numbers are essentially Carrier-derived. On heat pumps we check reversing valve operation and refrigerant charge together, because a low-charge system will show symptoms that look like a reversing valve fault and you can spend money on the wrong repair. On furnaces we run through igniter resistance and flame sensor microamp draw with instruments, not by eye. Near the bay we also check the outdoor coil for salt-pitting and blocked drain pans before signing off.
Bay Area HVAC Service is our division for this work, operating out of San Ramon under CSLB license 1136642. The $99 on-site diagnosis is credited toward the repair. We give you a written quote before the repair. Our technicians hold EPA Section 608 Universal certification for any refrigerant work. Repairs carry a one-year warranty on parts and labor. New installs go out with ten years on parts, labor two years standard (ten years on our maintenance plan).

Common repairs we handle.
- Hot Surface Igniter Failure. The most common no-heat call on Tempstar gas furnaces in Martinez is a cracked or burned-out hot surface igniter. The furnace calls for heat, the inducer spins up, the board sends voltage to the igniter, and nothing lights. The board logs a lockout code and the cycle repeats two or three times before it shuts down hard. We measure igniter resistance cold to confirm it is out of spec, replace it with the correct ICP part, and verify flame signal before we close the panel.
- Flame Sensor Fouling and Nuisance Lockouts. A fouled flame sensor is the other high-frequency furnace complaint here. The burners light normally but the system shuts off after a few seconds, which the homeowner often describes as the furnace starting and then cutting out. The sensor rod accumulates oxide buildup and can no longer pass enough microamp current to satisfy the board. We clean or replace the sensor, verify the microamp reading is within the manufacturer band, and check the gas valve and manifold pressure while we are in there.
- Condenser Capacitor and Contactor Wear on Coastal-Side Units. On the west side of Martinez closest to the Carquinez waterfront, we see condenser run capacitors and contactors fail earlier than average because salt air accelerates oxidation on the contactor tips and the capacitor casing. Symptoms are an outdoor unit that hums but the compressor and fan do not start, or a unit that draws high amperage and trips the breaker. We test capacitance and contactor pull-in voltage, replace worn components, and clean the coil face of salt and debris before buttoning it back up.

FAQ
Tempstar in Martinez questions, answered.
-
Do you actually come out to Martinez, or is that too far from San Ramon?
Martinez is a regular stop for us. San Ramon to Martinez is under 30 miles and we run the I-680 and Highway 4 corridor routinely for jobs in Concord, Pleasant Hill, and the north end of the Diablo Valley. Scheduling is the same as any other city we cover. -
Is Tempstar a decent choice for a Martinez home, or should I be looking at a different brand if I need a replacement?
Tempstar is built on the Carrier platform, same engineering and same supplier parts as Heil and Comfortmaker. The tradeoff is a thinner dealer network compared to a full Carrier or Bryant dealer, but the hardware underneath is sound. For a ducted ranch house inland it performs the same job at a lower upfront cost. For a downtown craftsman without ducts, we would steer you toward a Mitsubishi Electric ductless system for the layout. At estimate time we also confirm what utility or manufacturer rebates actually apply to your specific model and situation. We install only Mitsubishi Electric for new ductless work and repair existing mini-splits of all brands. -
What does the $99 diagnostic actually include, and what kind of warranty do I get on the work?
The $99 covers a full system check: we pull any stored fault codes, test the relevant components with instruments, and give you a written quote for whatever needs fixing. If you approve the repair the $99 is credited toward the repair. Completed repairs carry a one-year warranty on both the part and the labor. If you are replacing equipment rather than repairing it, new installs carry a ten-year parts warranty, with labor at two years standard (ten years on our maintenance plan).
