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

Piedmont is a regular stop for us. The drive from San Ramon runs about 35 to 40 minutes depending on traffic on 580, and we schedule Piedmont calls the same way we schedule anything in the East Bay. There is no travel surcharge.

Is Comfortmaker a reasonable choice for the older homes in Piedmont, or should a homeowner push for a different brand?

It depends on the job more than the brand name. Comfortmaker equipment is built on the same platform as Carrier and Bryant, so the components are well-supported and the failure modes are predictable. For a Piedmont home with existing ductwork in decent shape, a Comfortmaker furnace or heat pump installed correctly will perform the same as a more expensive badge. The honest variable is always installation quality and whether the duct system can handle the new equipment. Where I would steer someone differently is a home with no ducts at all, where a ductless heat pump usually makes more sense than tearing walls open.

What does the $75 diagnostic actually include, and what warranty applies to the work?

The $75 covers me coming out, pulling fault codes, running the system through its sequence, and giving you a specific written quote for the repair before any work starts. If you approve the repair on the same visit, the $75 is waived and rolls into the job. Parts and labor on repairs are warranted for one year. If you end up doing a full system replacement, that work is covered by a 10-year parts and 10-year labor warranty.

Comfortmaker in Piedmont

Comfortmaker heating and cooling in Piedmont.

Piedmont sits in the Inner East Bay hills, a pocket of pre-war Tudors, Craftsman bungalows, and postwar ranches packed tight on steep lots. Most of the older homes were built with forced-air gas heat but no central AC, so a lot of what I see is either a furnace-only system that someone retrofitted cooling onto, or a heat pump that replaced an aging gas setup when the owner wanted to run on electricity. Comfortmaker is the ICP value line that shares its platform with Carrier and Bryant, so it shows up here whenever a contractor wanted to keep costs down on a replacement without straying far from proven components.

Diagnosing Comfortmaker equipment goes faster for me than it might for a tech who only sees it occasionally. The control board, igniter, inducer motor, and gas valve are the same family I pull fault codes from on Carrier and Bryant jobs. I read the board flash codes first, then work through the sequence rather than swapping parts by guess. In Piedmont specifically I pay extra attention to the outdoor unit before doing anything else: the bay influence pushes salt-laden air through this neighborhood regularly, and I have seen condenser coils and contactors corrode years ahead of what the same unit would show in Walnut Creek or Dublin.

Bay Area HVAC Service operates out of San Ramon and covers Piedmont without issue. The diagnostic is $75, and that fee is waived if you approve the repair. You get a written quote before I touch anything. Our technicians hold EPA Section 608 Universal certification; the company is licensed under CSLB 1136642. Repair work carries a 1-year warranty on parts and labor. Full system installations are backed by 10-year parts and 10-year labor coverage, and we confirm any available rebates at estimate time rather than printing a number that may have already changed.

Common repairs we do

What we close on the truck.

Cracked or failed hot-surface igniter. The silicon nitride igniter on Comfortmaker furnaces becomes brittle with age and cracks from thermal cycling, often without any visible sign until it stops making heat. The board will log a fault and lock out after two or three failed ignition attempts. I measure resistance across the igniter before assuming it has failed, because a weak inducer draft can also cause lockout and shares some of the same symptoms. The fix is a direct OEM replacement, which is straightforward on this platform and usually resolves the no-heat call in one visit.
Flame sensor carboned over and causing short-cycling. A dirty flame sensor is one of the most common service calls I get on any ICP-platform furnace, and Comfortmaker is no exception. The burner lights, runs for a few seconds, shuts off, and the cycle repeats until the board locks out on a safety trip. The sensor reads low microamp signal through the carbon buildup and the board interprets that as no flame present. I clean the rod with a fine abrasive, verify the microamp reading with a meter, and check the gas valve and pressure switch while I am in there since the same age that carbons a sensor often means other wear items are close behind.
Corroded contactor or failed run capacitor on the outdoor unit. Piedmont's proximity to the bay accelerates corrosion on outdoor equipment, and the contactor is usually the first casualty. A pitted or welded contactor can leave the compressor running continuously or prevent it from starting at all, and the failure often shows up mid-summer on the first string of hot days. Run capacitors fail the same way they do everywhere, but I see them trend earlier here than on identical units in the inland valleys. I test capacitance and contactor coil draw on every cooling call, and I replace both together if either is out of spec, since pulling the panel twice within a season wastes the customer's time and money.
