Straight answers
The questions homeowners ask us most — straight answers before you call.

We do — an independent service focused on Sub-Zero built-in refrigeration across Concord and East Contra Costa, with years of hands-on built-in experience and genuine OEM parts.
Yes. From Concord, the county's largest city, we run a broad route to Pleasant Hill, Walnut Creek, Clayton, Martinez, Pittsburg with realistic arrival windows.
In Concord's hot inland summers it is often a dirty condenser or a failing fan overheating the sealed system, not always a compressor. We check the cheaper causes first before quoting anything major.

Reviews
Real homeowners, real built-in repairs — a few of the 1,456 reviews behind our 4.9 rating.
Our 648PRO was running warm on both sides during that first May heat wave. The tech checked the condenser and airflow first instead of pushing a big part, found a failing evaporator fan, and had it cold again that afternoon. The $89 service call came off the bill once I approved the repair.
I expected to hear "you need a compressor." Instead he pulled the unit, showed me how packed the condenser coils were after our hot summers near Mount Diablo, cleaned and tested it, and it held temperature. Charged for a cleaning, not a sealed system. That kind of honesty is rare.
Two other companies replaced random parts on our built-in ice maker and it kept frosting over. These folks traced it to the fill-tube and water valve, used a genuine OEM kit, and explained the 365-day labor warranty up front. No more ice bridge.
FAQ
It depends on the fault. A diagnostic service call is $89 and is waived when you book the repair. Door gaskets, ice makers and many control parts typically run $275–$1,250, while sealed-system or compressor work is higher and is only quoted after we confirm it with pressure and electrical readings.
We are an independent appliance repair service focused on Sub-Zero built-in refrigeration across Concord and East Contra Costa. We are not a manufacturer or an authorized dealer; our technicians simply spend their days inside Sub-Zero built-ins and install genuine OEM parts.
Yes. We serve every Concord ZIP — 94518, 94519, 94520 and 94521 — plus Pleasant Hill, Walnut Creek, Clayton, Martinez and Pittsburg. Because Concord is the largest city in the county, it sits at the center of our route, so nearby towns get realistic, honest arrival windows.
Most Concord-area calls are scheduled within a couple of business days, and we give you a realistic window rather than an all-day wait. Tell us your model and symptoms when you call (650) 695-6963 so we arrive with the right parts and avoid a second trip.
Often, yes. Concord summers near Mount Diablo push built-in condensers and compressors hard. A dust-packed condenser coil or a failing fan makes a unit run warm and overheat — a much cheaper fix than a compressor. We always check airflow and the condenser before quoting sealed-system work.
It comes down to the failed part and the rest of the unit. A gasket, fan, board or ice maker is usually worth repairing. A failed sealed system on a very old unit is where replacement may make sense, and we will tell you honestly which way the numbers point — no pressure to replace a fridge that has good years left.
