Williams in Castro Valley
Williams heating and cooling in Castro Valley.
Castro Valley is a mix of post-war ranch homes in the flats and newer hillside builds. The older ranches, especially the ones that were never converted to central heat, run Williams wall and floor furnaces in the hallway or back rooms.
It sits a little inland from the bay, so it warms up more than Hayward or San Leandro in summer and cools off at night in winter. The furnaces cycle enough that thermocouples and pilots are the usual wear points.
ADRIUM runs HVAC through Bay Area HVAC Service. We are CSLB licensed, EPA 608 Universal certified, give written quotes, and waive the $75 diagnostic when you book the repair.
Common repairs we do
What we close on the truck.
- Hallway wall furnace blowing cold. On the Williams units in Castro Valley ranch homes, a weak thermocouple stops the main burner from proving even though the pilot is lit. I test the holding millivolts and replace the thermocouple.
- Floor furnace pilot keeps going out. Drafts through the floor grate blow out the pilot on older gravity floor furnaces. We check the pilot shielding and orifice, replace what is worn, and confirm the pilot holds against normal draft.
- Burner clogged with dust and lint. Floor units pull dust through the grate and the burner ports clog, giving weak uneven heat. We pull and clean the burner, inspect the heat exchanger, and reassemble it to fire evenly.
