Sealed system & compressor

Sub-Zero Sealed System & Compressor Repair

The sealed system — compressor, condenser, evaporator and refrigerant — is the heart of every Sub-Zero, and the one repair you don’t want guessed at. It needs proper diagnosis and EPA-certified handling. We confirm the fault is genuinely in the sealed system before recommending this work, and we’re honest when a smarter, cheaper repair will do.

Symptoms we fix

Common sealed system repair problems

If your unit is doing any of these, we can almost certainly help — usually the same day.

Not cooling at all

A unit that runs but never gets cold — a classic compressor or refrigerant symptom.

Refrigerant leak

Gradual loss of cooling performance from a leak in the sealed lines.

Compressor faults

Hot compressor, clicking/overload cycling, or a unit that won’t start.

Dirty / failing condenser

Overheating and short-cycling from blocked coils or a failing condenser fan.

Frost on the suction line

A tell-tale sign of a restriction or charge problem in the system.

Repair-or-replace advice

An honest assessment of whether the sealed-system repair is worth it for your unit.

Reviews

What Bay Area homeowners say

4.9/5 · 749 verified reviews
Our built-in Sub-Zero stopped cooling overnight. They came the same day, found a failed evaporator fan, and had it cold again before dinner. Clear pricing, no drama.
— Lisa M., Palo Alto
I thought I needed a whole new fridge. Turned out to be a control board — they diagnosed it properly instead of throwing parts at it. Saved me thousands.
— Robert H., San Jose
Our Wolf range wouldn’t light. The tech replaced the igniter and cleaned up a burner the same visit. Knew the appliance inside out.
— David R., Menlo Park
Wine fridge was swinging in temperature and I have bottles I actually care about. They recalibrated the zones and replaced a sensor. Rock-steady since.
— Karen L., Los Altos
The ice maker had quit completely. They traced it to the water valve, not the whole module like another company wanted to replace. Honest and fast.
— Michael B., Danville
Replaced the door gaskets and dialed in the temps on our Sub-Zero column. Food’s fresher, the bills dropped, and the tech left the kitchen spotless.
— Ashley T., Redwood City

FAQ

Frequently asked questions

Are you an authorized or factory-certified Sub-Zero repair service?
No — and we’re upfront about that. We’re an independent repair company with years of hands-on Sub-Zero and Wolf experience. We are not affiliated with, authorized by, or certified by Sub-Zero Group, Inc. or any manufacturer. What we offer is factory-level expertise, genuine OEM parts, and honest pricing without the long factory-service wait.
How fast can you come out?
In most of the Bay Area we offer same-day or next-day service, and many repairs are finished in a single visit. Call (650) 668-1172 or book online and we’ll give you the soonest realistic window.
Which brands do you repair?
We specialize in high-end built-in appliances: Sub-Zero, Wolf and Cove (all built by Sub-Zero Group), plus Viking and Thermador. Refrigeration, freezers, ice makers, wine storage, ranges, ovens, cooktops and dishwashers.
Do you use genuine parts?
Yes. We install genuine OEM parts matched to your exact model and serial number — never generic substitutes that can void your warranty or fail early.
Do your repairs come with a warranty?
Yes — every repair is backed by a 365-day warranty on our labor, plus a parts warranty. If something isn’t right after our visit, we come back and make it right at no extra charge.
How much does a repair cost?
It depends on the model and the fault, but you always get a clear, flat-rate quote before any work begins — no surprise charges and no mystery fees. We diagnose first so you’re paying to fix the actual problem.
Should I repair or replace my Sub-Zero?
We’ll give you a straight answer based on the unit’s age and condition — not a sales pitch. Many Sub-Zero units run 20+ years with the right care, so a smart repair usually beats an expensive replacement. When it doesn’t, we’ll tell you.
What should I do before the technician arrives?
If the unit isn’t cooling, move perishables to a backup cooler and clear space around the appliance so we can work safely. That’s it — we bring everything else.
