How do you reach Sunnyvale from San Ramon?

Bay Area HVAC Service covers Sunnyvale and the South Bay regularly. From San Ramon I take 680 south, usually 45 to 60 minutes depending on the Sunol grade. I batch Sunnyvale with Mountain View, Cupertino, and Los Altos calls so the drive is efficient and your window is real.

I have an Eichler, can you work on its wall furnace?

Yes. Eichler slab homes were designed around in-wall and floor furnaces, and a Williams unit is a correct fit. We repair the pilot, thermocouple, and valve, and replace a unit past service life with the right model rather than forcing a duct retrofit the home cannot easily take.

What is the diagnostic fee?

The diagnostic is $75 and waived with the repair. You get a written quote first. Repairs are warranted 1 year, and a new Williams install carries 10 year parts and 10 year labor.

Williams in Sunnyvale

Williams heating and cooling in Sunnyvale.

Sunnyvale's older Heritage District has period bungalows that often ran a single Williams wall furnace, and the Eichler tracts near Fairwood used in-wall and floor furnaces because their flat-roof slab design left no good path for ducts. We service all of these units across the city.

Sunnyvale's bay-moderated valley climate is mild, so the heating load is gentle and steady, and the Williams failures here are mostly age-related, worn pilots and tired valves. A clean repair usually returns the unit to several more years of good service.

Eichler owners in particular call us, because their slab homes have limited heating options and a wall furnace is part of the original design. We repair the pilot, thermocouple, and valve, and when a unit is past service life we replace it with the correct Williams model rather than forcing an awkward retrofit.

Common repairs we do

What we close on the truck.

Eichler wall furnace pilot dropout. In the Sunnyvale Eichlers the Williams wall furnace runs as the main heat and the standing pilot eventually drops from a weak thermocouple or clogged orifice. I clean the orifice, confirm a steady pilot flame, and replace the thermocouple so the gas valve holds open through the full cycle.
Gas valve failure. On the older Heritage District units the Williams gas valve gives out after decades of mild but constant winter use. I check the thermostat and limit circuit, test the valve coil and body, and replace it with the correct Williams-spec valve at proper manifold pressure.
Fan-assisted blower motor wear. On the fan-assisted Williams Monterey wall units the blower motor bearings dry out and the fan gets loud or weak. I check the motor and capacitor, service or replace the motor, and clear the air path so the unit moves the heat it makes into the room.
