Williams in Lafayette

Williams heating and cooling in Lafayette.

Lafayette is older homes tucked into the hills off Mt Diablo Boulevard plus newer hillside builds. A lot of the older homes and their additions heat with Williams wall furnaces because the wooded lots and split levels made ducting awkward.

Lafayette sits inland in the Diablo Valley, so summers are warm and winter mornings are genuinely cold, and a wall furnace in a back room or addition gets used in the cold months. We service ignition, gas valves, and thermocouples on those units.

ADRIUM runs HVAC through Bay Area HVAC Service. We are CSLB licensed and EPA 608 Universal certified, give written quotes, and waive the $75 diagnostic with repair.

Common repairs we do

What we close on the truck.

  • Hillside addition furnace runs then quits. Cold-morning cycling in Lafayette wears the thermocouple, so the unit lights then drops the burner. I test cold and hot millivolt output and replace the thermocouple.
  • Gas valve failure on an older unit. Older Williams wall furnaces here lose the gas valve coil and the burner will not open. We confirm the pilot proves, test the valve, and replace it with the correct part.
  • Pilot blown out by drafts. Wooded hillside homes get drafty, and the pilot on an older wall unit blows out. We check the pilot shielding and orifice, replace what is worn, and confirm it holds against normal draft.

FAQ

Williams in Lafayette questions, answered.

  • How far is Lafayette from your San Ramon base
    Lafayette is about 20 to 30 minutes from San Ramon up 680, near Orinda, Walnut Creek, and Alamo. We give an arrival window and call when we are close.
  • My home has no ducts. Is a wall furnace the right fix
    For a single room or addition without ducts, a Williams wall furnace is the simplest like-for-like fix. If you want zoned ductless heat pumps instead we can quote that too.
  • What warranty comes with a new install
    A furnace install carries 10-year parts and 10-year labor. Repairs are warranted one year, and the quote is in writing before we start.
