Our El Sobrante house is up the hill. Does that change anything for the AC?

Sometimes. A hillside lot can put the outdoor unit on a small pad or a deck with little clearance, and afternoon sun hits it harder on an exposed slope. We check the space around the coil, the pad and the line set as part of the diagnosis. ADRIUM holds EPA 608 Universal certification if the refrigerant side needs work.

The GrandAire furnace smells like dust the first time it runs in the fall. Is that a problem?

A dusty smell on the first run of the season is normal, since dust burns off the heat exchanger. A smell that lasts, a sharp electrical odor or any hint of gas is different: shut the furnace off and call us. We check the burner, the heat exchanger and the wiring on that visit.

Do you service GrandAire systems in El Sobrante condos?

Yes. In a condo the equipment may be a furnace in a closet or a heat pump with an air handler, and the outdoor unit may sit in a shared area. Tell us about access and any building rules, and we plan the visit around them.

GrandAire in El Sobrante

GrandAire heating and cooling in El Sobrante.

About three quarters of El Sobrante's housing went up between 1940 and 1979, a mix of old ranchettes, later subdivisions and apartment and condo buildings. Homes also climb into the hills above San Pablo Dam Road. That shapes GrandAire work here: a furnace may sit in a crawlspace or a garage, the vent pipe can be older than the equipment, and the outdoor unit may stand on a sloped lot.

GrandAire is value equipment on the Carrier platform, so the fixes rely on common parts rather than special orders. For El Sobrante, our technician is based in Benicia. You pay a $99 diagnostic, credited toward the repair when you go ahead, and you see the price in writing before any work. CSLB #1136642.

Common repairs we handle.

Pressure switch lockout on an older vent. When a newer furnace is tied into an old vent, a sagging pipe, a blocked cap or water sitting in the inducer housing can keep the pressure switch open. The furnace tries, then locks out. We read the board code, test the switch and the vacuum at the inducer, and look at the vent run before replacing anything.
Outdoor unit tilting on a hillside pad. A condenser pad on a slope can settle and tilt over the years. A tilted unit strains the refrigerant lines and can rattle against its base. We level the pad, check the line set for kinks or rubbing and look for oil at the joints, which is where a leak usually shows.
Crawlspace furnace pulling air through a torn return. In a crawlspace install, a torn or disconnected return duct pulls damp, dusty air from under the house into the furnace. Filters clog early and the heat exchanger runs hot. We inspect the return run, seal or reconnect it, and check the temperature rise afterward.
