You are based in San Ramon. How long does it take you to reach Millbrae for a furnace call?

We come over the San Mateo Bridge on 92 and up 101, which is about 50 minutes from San Ramon outside commute hours. We schedule Millbrae alongside Hillsborough stops on Peninsula days, so morning windows fill first. Book a day ahead and we hit the window.

Are Comfortmaker parts harder to get than Carrier parts?

No. Comfortmaker rides the ICP platform, so ignitors, inducers, boards, and capacitors interchange with Heil and Tempstar and cross-reference to Carrier numbers. Most repairs come off my van stock the same visit.

My Comfortmaker furnace is 22 years old. Repair or replace?

I give you both numbers in writing after the $75 diagnostic, which we waive if you repair. A cracked heat exchanger means replacement, no debate. An ignitor or inducer on an otherwise clean unit is worth fixing. If you replace through us, the install carries 10 year parts and 10 year labor.

Comfortmaker in Millbrae

Comfortmaker heating and cooling in Millbrae.

Comfortmaker is a contractor-channel brand from International Comfort Products, and Carrier owns ICP. That matters in Millbrae because a lot of the mid-century houses between El Camino and the hills got Comfortmaker furnaces when a builder or a landlord wanted Carrier engineering without the Carrier price. The ignitor, the inducer, the control board are the same platform parts you find in Heil and Tempstar, so my van stock covers them.

The typical Millbrae call is an 80 percent gas furnace in a hallway closet or a low attic, 15 to 25 years old, short cycling or refusing to light on the first cold morning of the season. I also see newer Comfortmaker heat pumps going into homes near the BART and Caltrain stations where owners are getting off gas. Both are straightforward machines when you know the ICP fault codes.

We run the same $75 diagnostic on every Comfortmaker unit, waived when you approve the repair, and the repair carries a one year warranty on parts and labor.

Common repairs we do

What we close on the truck.

Hot surface ignitor cracked, furnace clicks but never lights. The silicon nitride ignitor on ICP furnaces is a wear item. It glows, weakens over 5 to 8 years, then cracks. The board flashes an ignition lockout code and the house goes cold. I carry the ignitor on the van, so this is usually a one-visit fix in Millbrae.
Draft inducer motor whining or seized. The inducer pulls combustion air before the burners fire. On Comfortmaker units in Millbrae's damp Peninsula air the bearings rust and the motor screeches at startup, then the pressure switch never closes and the furnace locks out. Replacing the inducer assembly restores safe venting.
Heat pump stuck in defrost or icing over. Comfortmaker heat pumps use the ICP defrost control. When the board or its coil sensor drifts, the outdoor unit ices into a block during cool foggy nights. I test the sensor resistance and the board timing before touching refrigerant, because most of these calls are electronics, not a leak.
