Why choose us
Why homeowners call Ace Appliance Service for Sub-Zero repair
Built-in Sub-Zero refrigeration uses sealed systems, airflow, and electronic controls that behave differently from a standard refrigerator. Getting the cooling, defrost, and temperature-control systems right takes careful diagnosis before any repair is recommended. Here's what you get when Ace Appliance Service handles it:
Owner-operated, no subcontractors
The technician who diagnoses your Sub-Zero is the same person who repairs it, hands-on from the first call to the final test.

Same-day / next-day appointments
A Sub-Zero that's not cooling can't wait. Most calls get scheduled same-day or next-day.
Sub-Zero refrigeration
Why accurate diagnosis matters
Built-in Sub-Zero refrigeration is engineered differently than a standard kitchen refrigerator. The compressor, evaporator, and airflow are matched to a sealed cabinet, and the electronics that manage defrost, temperature control, and ice production don't always fail the same way twice — even on the same model.
Ace Appliance Service has hands-on experience with these systems — cooling, defrost, ice makers, fans, and door seals. Before recommending a repair, we diagnose what's actually happening inside the unit, not just the symptom at the door, since a wrong guess on equipment like this means paying twice.
It's also why we service Sub-Zero regularly alongside brands like Viking, Thermador, Wolf, and Liebherr.

Questions
Sub-Zero repair FAQ
Do you repair older Sub-Zero refrigerators?
Yes. We work on both current and older built-in Sub-Zero refrigerators, freezers, and wine storage units. If you're not sure whether your model is still repairable, call and describe what's happening — we can usually tell you before we come out.
Is a Sub-Zero refrigerator worth repairing?
In most cases, yes. Sub-Zero units are built to last — commonly 20 to 35 years or more with proper maintenance — so most problems (a worn seal, a failed fan, an ice maker, a control board) are straightforward repairs next to replacing the whole unit. We'll give you an honest read after diagnosis, including on the rare occasion when replacement makes more sense. See our repair vs. replace guide for how we think about it generally.
Why is my Sub-Zero refrigerator not cooling?
It can come from a few different places: a sealed system issue, a failing evaporator or condenser fan, a blocked defrost drain, or a control board problem. Because these systems work differently from a standard refrigerator, accurate diagnosis matters before any repair is attempted.
What affects the cost of Sub-Zero refrigerator repair?
Cost depends on the diagnosis, the model, the parts required, and the labor involved. We diagnose the unit first and give you a clear price before starting any repair, so schedule a visit and we'll walk you through it.
Do you repair Sub-Zero ice makers?
Yes. We repair Sub-Zero ice makers that have stopped producing ice, are jammed, running slow, or leaking around the bin.
Where do you provide Sub-Zero refrigerator repair?
Throughout Seattle, Bellevue, Mercer Island, Medina, Clyde Hill, Everett, Kirkland, Redmond, Bothell, and the rest of King and Snohomish County.
