Williams in Danville
Williams heating and cooling in Danville.
Danville mixes older homes near downtown and the Iron Horse corridor with newer subdivisions up the hills. The older homes and the growing number of in-law units and ADUs often run a single Williams wall furnace because they were built without ducts.
Danville is inland, so summers are hot and winter mornings are cold, and a wall furnace in a back room or an ADU has to fire reliably when it counts. We service ignition, gas valves, and thermocouples on those units.
ADRIUM is based right next door in San Ramon, so Danville is one of our shortest runs. HVAC goes through Bay Area HVAC Service, CSLB licensed, written quotes, and seven days a week.

Common repairs we handle.
- ADU wall furnace not holding pilot. A new ADU's Williams unit can clog its pilot orifice during construction dust or after sitting unused. I clean the pilot path, replace the thermocouple, and confirm a steady flame.
- Thermocouple worn from cold-morning cycling. Inland Danville cold makes the unit cycle hard, so the thermocouple fails and the burner drops after lighting. We test holding millivolts and replace the thermocouple.
- Gas valve coil failure. On older Williams wall furnaces the gas valve will not open even with a good pilot. We test the valve, confirm the safety circuit, and replace the valve with the correct part.
