Do you actually come out to Martinez, or is that too far from San Ramon?

Martinez is a regular stop for us. The drive from San Ramon through Danville and up the 680 corridor takes about thirty minutes depending on traffic. We schedule Martinez calls the same way we do Tri-Valley work, no trip surcharge.

Is Comfortmaker a reasonable choice for the older ducted homes common in Martinez?

For a ducted retrofit it is a solid option. Comfortmaker sits on the Carrier engineering platform alongside Heil and Tempstar, so the components are well-proven. The honest answer is that the equipment tier matters less than duct condition and installation quality in a mid-century house. If the existing ductwork is leaky or undersized, a new furnace or heat pump will not fix that, and I will tell you so before the install rather than after.

What does the $75 diagnostic cover, and what warranty applies after the repair?

The $75 covers a full system evaluation: pulling fault codes, testing electrical components, checking pressures or combustion as appropriate, and giving you a written quote for the repair. If you approve the repair on the same visit, the $75 comes off the total. Work we do on-site carries a one-year parts and labor warranty. If the job turns into a full replacement, installs are backed by ten years on parts and ten years on labor.

Comfortmaker in Martinez

Comfortmaker heating and cooling in Martinez.

Martinez sits at the edge of where Suisun Bay air pushes inland, and that geography shows up in the equipment I work on here. The older neighborhoods along Alhambra Avenue and the hillside streets east of downtown have mid-century and pre-war homes, many with original duct systems and furnaces that have been swapped a few times. Comfortmaker shows up frequently as a contractor-supplied replacement in those houses, priced right for a ducted retrofit. Further inland toward the Diablo foothills the summers get genuinely hot, so the AC side of a heat pump or a matched condenser matters as much as the heat.

On Comfortmaker equipment, diagnosis moves fast because the control board, igniter, inducer motor, and gas valve are carrier-platform components. I pull fault codes from the board first, cross-check against the inducer vacuum, and test the flame sensor before assuming anything else is wrong. One thing specific to coastal-adjacent Martinez: the outdoor coil and contactor on condensers see salt-laden bay air, especially on properties closer to the waterfront. I always pull the contactor and check for pitting and inspect the capacitor before calling a heat pump or AC system fully evaluated.

Bay Area HVAC Service is our HVAC division, operating out of San Ramon and making regular runs to Martinez. The diagnostic fee is $75 and we waive it if the repair goes forward. Every job gets a written quote before a wrench moves. I hold EPA Section 608 Universal certification and we carry CSLB license 1136642. Repair work is backed by a one-year warranty; replacement installs carry ten years on parts and ten years on labor.

Common repairs we do

What we close on the truck.

Cracked or failed igniter causing no-heat lockout. The silicon nitride igniter on Comfortmaker 80 and 96 percent furnaces cracks from thermal cycling and stops drawing enough current to light the burner. The board will log a no-ignition fault after two or three failed trials and lock out. I measure resistance across the igniter before condemning it, because a weak reading that is still in spec can still fail at operating temperature. Replacement takes under an hour and the furnace is back in service the same visit.
Carboned flame sensor causing short-cycling. A flame sensor coated with oxidation or combustion residue cannot pass enough microamp signal back to the control board to confirm the burner is lit, so the board shuts the gas valve within a few seconds of ignition. The furnace cycles repeatedly without ever staying on. On Comfortmaker units in Martinez, especially those running through damp winter seasons, this is one of the most common calls I get. A thorough cleaning and a microamp draw test with the system running confirms whether the sensor is serviceable or needs replacement.
Failed condenser capacitor or pitted contactor on the AC or heat pump. Bay air accelerates corrosion on outdoor electrical components. A capacitor that has drifted out of spec causes the compressor or fan motor to struggle on startup, pulling high amperage and sometimes tripping the breaker. A pitted contactor creates intermittent connection and causes the outdoor unit to hum without starting. I test capacitance directly with a meter and inspect contactor contacts before replacing anything, so the written quote reflects exactly what failed and why.
