Williams in Millbrae
Williams heating and cooling in Millbrae.
Williams is a wall and floor furnace brand, and that single fact tells you who needs it in Millbrae. The mid-century single-family homes here were often built without ducted central heat, and a lot of them still run the original Williams wall furnace in the hallway. Add the in-law units and backyard ADUs that Millbrae has been approving near the transit corridor, and there is a steady population of Williams heaters that nobody services until they fail in November.
We service and replace Williams wall and floor furnaces under CSLB #1136642. On replacements you get a written quote first, and installs carry our ten-year parts and ten-year labor warranty. On repairs the $75 diagnostic is waived when you approve the work, and the repair itself is warrantied for one year.
One note on rebates: programs change constantly, so we do not quote dollar figures from memory. We confirm what is actually paying at estimate time.
Common repairs we do
What we close on the truck.
- Pilot light will not stay lit. The classic Williams call. Nine times out of ten it is a worn thermocouple or a pilot orifice clogged with decades of dust, both quick fixes. If the pilot drops only when the burner fires, I look harder at the gas valve and the vent draft before touching anything else.
- Furnace lights but the smell of burning dust never clears. A Williams wall furnace that has sat unused collects lint in the burner compartment and heat exchanger fins. First-fire smell should clear in an hour. If it persists, I pull and clean the burner assembly and inspect the heat exchanger for cracks, which is a safety item I will not skip on an older unit.
- Weak heat from a floor furnace in an older Millbrae house. Floor furnaces lose output when the grille and combustion chamber choke with debris from above and the gas pressure drifts out of spec. I clean the chamber, verify manifold pressure, and check clearances. When the heat exchanger is done, I quote a Williams replacement honestly rather than patching something unsafe.

FAQ
Williams in Millbrae questions, answered.
-
You come from San Ramon. Is a single wall furnace call in Millbrae worth the trip for you?
Yes, we do not make a special trip just for one call. Millbrae sits on our Peninsula route with Hillsborough next door, so a Williams furnace visit gets grouped with other work on that side of the bridge. The drive from San Ramon runs about 50 minutes via 92, and you get a set arrival window, not a maybe. -
My ADU has a Williams furnace the builder put in. Do you service new units or only old ones?
Both. The newer direct-vent Williams units going into ADUs need different diagnostics than the 40-year-old gravity furnaces, but we work on the full line. If your ADU unit is still under manufacturer parts warranty we tell you before charging you for a part. -
Should I repair my old Williams furnace or replace it?
The heat exchanger decides. If it is intact, most Williams repairs are inexpensive and the unit can run for years. If it is cracked, replacement is the only safe answer, and our installs carry ten-year parts and ten-year labor coverage so the math is clear either way.
