From our records
Refrigerator repair in Berkeley: what we actually see.
7 refrigerator repairs at 5 homes in Berkeley in the last 24 months. Counted from completed jobs in our own records as of 2026-09-02.
Median time from booking to visit on those calls since February 2026: 1.1 days over 7 bookings, so most Berkeley visits get booked within 2 days. That is a measured median, not a promise.
Why this happens
What we look for first.
- Condenser packed with dust. The number one Sub-Zero no-cool call by a wide margin. The condenser sits behind the top grille and pulls dust, pet hair, and cabinet lint until airflow chokes. The compressor overheats and trips on its own thermal limit. Half of these clear up with a proper condenser clean. Sub-Zero wants this done every six to twelve months and almost nobody does it.
- Evaporator fan motor stalled. Dual refrigeration means a separate evaporator and fan for the fresh food side and the freezer side. When one fan stalls, that one compartment drifts warm while the other stays fine. A fresh-food section warming while the freezer holds is the classic tell.

Serving Berkeley
Berkeley: response and coverage.
Berkeley sits in our Inner East Bay zone. We run it on planned days, often paired with Oakland calls. Same-week scheduling typical.
Neighborhoods we cover regularly in Berkeley: Berkeley Hills, North Berkeley, Elmwood. Beyond those, our service area in Berkeley covers the city limits.
Berkeley kitchens are mixed. The flatlands and apartment stock in South and West Berkeley run everyday brands: GE, LG, Samsung, Whirlpool, and Bosch. North Berkeley and the hills add built-ins (Sub-Zero, Wolf, Thermador, Fisher & Paykel) in remodeled kitchens.
Pricing and warranty

$99
Diagnostic visit. Credited toward the repair.
-
Typical
Repair pricing is provided in a written estimate after the $99 on-site diagnosis, which is credited toward the repair.

Warranty
Our full sealed-system rebuilds on built-ins carry a 2-year parts and labor warranty, and partial sealed repairs carry 1 year. Nobody else in this market backs the work that long. We do it because we stand behind the quality. To be clear, that covers the parts we replace and the labor to install them, not the rest of the refrigerator and not components that were already in the unit when we got there. Everything in writing before we start. 90 days on most other repairs, 1 year on inverter boards.
