Our Comfortmaker furnace in a downtown Vallejo Craftsman is noisy. Is it the furnace or the ducts?

It can be either. Hum and rattle tend to come from the cabinet; whistling or booming usually comes from undersized returns or loose duct panels in an older house. We listen at the furnace and at the registers, measure static pressure, and tell you which one to fix first.

Is a Comfortmaker heat pump enough heat for a Vallejo winter?

For a correctly sized unit, yes. Winters here stay mild enough that a heat pump seldom needs backup heat, and it covers the few warm days as well. We run a load calculation and look at the electrical panel before quoting, since a panel upgrade can change the math.

Vallejo water is hard. Does that affect a Comfortmaker furnace or heat pump?

Not directly, since neither one uses household water. It matters for a whole-house humidifier if you have one, because hard water leaves scale on the pad and the water valve. We look at the humidifier while we are there and replace the pad when it has crusted over.

Comfortmaker in Vallejo

Comfortmaker heating and cooling in Vallejo.

Vallejo's climate is mild and shaped by the bay, and it can average about 10 degrees cooler than the inland cities around it. For a Comfortmaker system that means a long heating season and a light cooling one. The furnace or heat pump does most of the work, so its igniter, flame sensor and blower collect the hours.

Comfortmaker is built by International Comfort Products, which Carrier owns, and it shares control boards, igniters, inducers and gas valves with Heil, Tempstar and the rest of the Carrier family. That keeps parts easy to find, whether the system heats a downtown Craftsman or a home in Hiddenbrooke.

The technician we send to Vallejo is based in Benicia, one town over. The diagnostic is $99 and is credited toward the repair, with a written quote before any part goes in. Our contractor's license is CSLB #1136642.

Common repairs we handle.

Flame sensor fouling and short heating cycles. A long heating season lets residue build on the flame sensor rod. The burners light, run a few seconds, then shut off because the board loses the flame signal, and the furnace tries again and again. We clean the rod, measure the flame signal under fire and check the burners for the same buildup.
SoftSound blower getting loud or rattling. The SoftSound line is built around quieter blower operation, so a new noise from it stands out. A wheel loose on its shaft, a wheel caked with dust or a worn motor bearing are the usual causes. We clean and balance the wheel, check motor amps against the label and replace the motor if it is failing.
Heat pump running but blowing cool air in winter. On a Comfortmaker heat pump, a stuck reversing valve or a failed defrost control leaves the unit running without heating the house. We check the valve's solenoid and the defrost board, measure refrigerant pressures, and confirm the heat pump switches modes cleanly before we leave.
