Even a few degrees off can put food at risk. This is one of the most common Sub-Zero complaints we see, and it usually points to a condenser, thermostat, or airflow issue — all diagnosable on the first visit.

Frozen lines, faulty water valves, worn inlet seals - ice maker problems come in a lot of forms. We carry the parts for most major brands and can typically resolve it same day.

A little frost is normal. Heavy buildup isn't - it usually means a door gasket is failing or the defrost system needs attention. Left alone, it strains the compressor and shortens the life of the unit.

Rattling, buzzing, clicking, or humming after a refrigerator has been quiet for years is worth paying attention to. It often traces back to a fan blade, compressor mount, or condenser - things that are straightforward to fix when caught early.

The condenser and evaporator fans do the quiet work that keeps everything cold. When either starts to fail, the whole unit suffers. We test both as part of every diagnostic visit.

A worn gasket forces your refrigerator to run longer and work harder — which shows up on your energy bill before it shows up anywhere else. Seal replacements are one of the most cost-effective repairs we do.

Modern Sub-Zero units are built with detailed onboard diagnostics. We know what those codes mean and use them to get to the root cause faster without unnecessary guesswork or parts.
