SUB-ZERO BUILT-IN REFRIGERATOR · MARTINEZ
Sub-Zero built-in refrigerator not cooling in Martinez? We fix it.
Sub-Zero built-ins and columns run a dual refrigeration design that fails in patterns most generalist techs never learn. We run these every week and know where to look first.

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 Martinez
Martinez: response and coverage.
Martinez is a 30 to 35 minute run up 680. We fold it into the Diablo Valley window with Concord and Pleasant Hill, so same-week scheduling is the norm.
Neighborhoods we cover regularly in Martinez: Alhambra Valley, Vine Hill, Virginia Hills. Beyond those, our service area in Martinez covers the city limits.
Martinez is the county seat, and most kitchens run everyday brands: Whirlpool, GE, LG, KitchenAid, and Samsung. Downtown and the streets off Alhambra Avenue are older Victorian and Craftsman homes retrofitted over the years. Vine Hill and Virginia Hills add mid-century ranch stock. Out in Alhambra Valley a few estate remodels carry premium built-ins, but that's the small end of the work here.

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.
