Williams in Berkeley

Williams heating and cooling in Berkeley.

Berkeley has some of the oldest housing stock we work in. The Brown Shingle homes in the hills and the flatland bungalows near campus very often heat with a Williams wall furnace instead of a ducted system, especially the units that were never updated.

The bay keeps Berkeley mild, so these furnaces idle more than they run hard. That leaves carbon and corrosion on the pilot and burner over the years, which is the root of most no-heat calls we get from here.

ADRIUM runs HVAC through Bay Area HVAC Service. We are CSLB licensed and EPA 608 Universal certified, the $75 diagnostic is waived with repair, and we will tell you plainly when a unit is past saving.

Common repairs we do

What we close on the truck.

  • No heat from a decades-old wall furnace. On the older Williams gravity units in Berkeley flats, a weak thermocouple is the usual cause. The pilot lights but the main burner never proves. I test millivolt output and replace the thermocouple.
  • Yellow lazy flame and soot. Years of light idling leave dust and carbon in the burner. The flame turns yellow and sooty. We clean the burner and orifices and confirm a clean blue flame and proper draft.
  • Cracked heat exchanger on an aged unit. Many hill-home Williams units are 40-plus years old. When we find a cracked heat exchanger we shut the unit down for safety and quote a replacement rather than patch it.

FAQ

Williams in Berkeley questions, answered.

  • How long to reach Berkeley from San Ramon
    From San Ramon it is roughly 35 to 45 minutes through the tunnel toward Oakland and Orinda, both near Berkeley. We give you an arrival window and call ahead.
  • My house has no ducts. Is a wall furnace my only option
    Not the only option, but a Williams wall furnace is the simplest like-for-like fix for a ductless older home. If you want zoned ductless heat pumps we can quote that too.
  • Will you replace an unsafe unit the same week
    If we red-tag a furnace for a cracked heat exchanger, we move quickly. We can usually get a written replacement quote out same or next day and schedule the install within the week.
