Williams in Hillsborough

Williams heating and cooling in Hillsborough.

Hillsborough is large estate properties on the Peninsula, and the main residences run full ducted systems. Where Williams units come in is the guest houses, pool houses, and detached staff quarters that were built without their own ductwork.

The climate is mild and Peninsula-moderated, so these secondary-building furnaces do not work hard, but units that sit idle most of the year develop clogged pilots and aged gas valves. We service those and keep them safe.

ADRIUM handles HVAC through Bay Area HVAC Service. We give written quotes, we are EPA 608 Universal certified, and on estate work we coordinate gate and property-manager access ahead of the visit.

Common repairs we do

What we close on the truck.

  • Guest-house furnace will not light after long idle. A wall furnace that sits unused most of the year clogs its pilot orifice and collects debris in the tubing. I clean the pilot path, replace the thermocouple, and confirm a stable flame.
  • Gas valve stuck closed. Aged Williams valves on older estate units stick and the burner never opens. We test the valve and the safety circuit and replace it with the correct Williams part.
  • Flame dropout in a humid pool house. Damp pool-house air corrodes the flame-sensing path and the burner drops. We clean or replace the pilot and sensor assembly so the flame signal holds in the humidity.

FAQ

Williams in Hillsborough questions, answered.

  • How long is the drive to Hillsborough from San Ramon
    Hillsborough is about 50 to 60 minutes from our San Ramon base over the San Mateo Bridge, near Atherton and Palo Alto. We set a firm window and arrange gate or property-manager access in advance.
  • Can you service just the detached guest quarters
    Yes. Most of our Hillsborough Williams work is the secondary buildings on a single ductless wall furnace. We service or replace just that unit.
  • Do you provide documentation for the estate manager
    Yes. Every visit comes with a written quote and clear scope, which makes approval and recordkeeping straightforward for an estate manager.
