Williams in Concord
Williams heating and cooling in Concord.
Concord has a deep stock of mid-century homes around the central neighborhoods and a lot of older rentals. Plenty of those, and the converted units behind them, never got ducts, so a Williams wall furnace is the heat source.
Concord sits in the Diablo Valley and runs hot in summer with cold winter mornings, so these wall furnaces actually get used hard in the cold months. That use shows up as worn gas valves and tired thermocouples.
ADRIUM handles HVAC through Bay Area HVAC Service. We are CSLB licensed and EPA 608 Universal certified, we work seven days, and the $99 diagnostic is credited toward the repair.
Common repairs we do
What we close on the truck.
- Wall furnace runs then quits. Hard winter cycling in Concord wears the thermocouple, so the unit lights and then drops the burner once it warms. I test cold and hot millivolt output and replace the thermocouple.
- Gas valve failure. On older Williams wall units that run a lot here, the gas valve coil weakens and the burner will not open. We confirm the pilot proves, test the valve, and replace it with the correct part.
- Pilot will not stay lit in a rental unit. Neglected rental furnaces collect dust in the pilot path. The pilot lights then drops. We clean the pilot assembly and orifice and replace the thermocouple so it holds reliably for tenants.
