Williams in Los Altos
Williams heating and cooling in Los Altos.
Los Altos has a strong stock of mid-century ranch homes near the downtown village and the older neighborhoods. A number of those homes, and their additions, heat a back room with a Williams wall furnace because they were built without full ducting.
The South Bay climate here is mild and dry, so these units idle more than they run hard, but the additions and ductless rooms still rely on a wall furnace for that cold corner, and the pilots and valves age out over time.
ADRIUM runs HVAC through Bay Area HVAC Service. We are CSLB licensed and EPA 608 Universal certified, give written quotes, and credit the $99 diagnostic toward the repair.

Common repairs we handle.
- Addition wall furnace not igniting. On older Williams units serving a ductless addition, a failed thermocouple is the common no-heat cause. I confirm the pilot lights, test millivolt output, and replace the thermocouple.
- Sooty burner from light idling. In the mild climate the furnace idles more than it fires, leaving carbon on the burner and a yellow flame. We clean the burner and orifices and confirm a clean blue flame and draft.
- Gas valve no longer opening. Decades-old Williams gas valves stick closed and the burner will not light. We test the valve and safety circuit and replace it with the correct Williams part.

How do you schedule a visit in Los Altos?
Our Peninsula technician is based in San Mateo and covers Los Altos. Los Altos is near Mountain View, Menlo Park, and Palo Alto. We book a firm window and call when we are close. -
My addition has no ducts. What heats it best
A Williams wall furnace is the simplest like-for-like heat for a single ductless room. If you prefer a zoned Mitsubishi Electric ductless heat pump we can quote that option as well. We install only Mitsubishi Electric for new ductless work and repair existing mini-splits of all brands. -
Can you replace a unit that is past repair
Yes. If parts are gone or the heat exchanger is cracked we quote a like-for-like replacement in writing, with 10-year parts, labor 2 years standard (10 years on our maintenance plan) on the install.
