Expert Subzero Appliance Repair You Can Trust

When a Sub-Zero refrigerator, freezer, wine storage unit, or under-counter system stops cooling, you cannot trust your investment to a generic appliance technician. Sub-Zero products require advanced knowledge of sealed systems, factory-level training, and a specialist who understands the engineering behind these premium refrigeration systems.

At John’s Heating, Cooling, and Appliance Repair, we are proud to offer the most specialized independent Sub-Zero repair service in Georgia.
John is one of the very few technicians in the state who completed official Sub-Zero factory training in Madison, Wisconsin — the same facility where Sub-Zero builds its products.

Suppose you live in Atlanta, Buckhead, Marietta, Roswell, Peachtree City, Newnan, Fayetteville, Senoia, Sharpsburg, Griffin, or the surrounding areas. In that case, you finally have a local Sub-Zero expert who provides affordable, honest, premium-quality repair service.

FAQs – Sub-Zero Refrigerators, Freezers & Under-Counter Units

1. Why is my Sub-Zero refrigerator not cooling?

Common causes include evaporator leaks, dual-compressor issues, dirty condenser coils, or sensor failure.
These require trained Sub-Zero diagnostics.

2. Why does my Sub-Zero have frost or ice behind the back panel?

This usually indicates evaporator corrosion — a known issue on many older Sub-Zero models.

Not enough freon in the sealed system.

3. Why is my Sub-Zero making loud humming or fan noises?

Often caused by failing evaporator fans, condenser fans, or ice buildup on the coil.

4. My Sub-Zero refrigerator is warm, but the freezer is cold — why?

Usually a sealed-system issue: low freon level.  The compressor has stopped running.

5. Why won’t my Sub-Zero door seal properly?

The patented vacuum door seal may be worn, torn, or failing.  We replace these routinely.

The drain line is clogged.

6. Why is water leaking inside my Sub-Zero refrigerator?

Drain clogs, cracked pans, or defrost cycle issues are the most common causes.

7. Should I repair or replace an older Sub-Zero refrigerator?

Most Sub-Zero units last 20–25 years with proper repairs — replacing is rarely necessary.

8. Why is my Sub-Zero freezer not freezing even though the fan runs?

This often indicates a sealed system failure,

Low Freon

Bad Compressor

requires a trained Sub-Zero specialist.

9. Why does my Sub-Zero freezer keep developing frost?

A failing gasket, defrost issue, or evaporator sensor is usually the cause.

10. Why is my Sub-Zero under-counter fridge constantly running?

Most likely warm air leaks, dirty coils, or a failing thermostat/compressor.
We perform complete diagnostics to restore proper cooling.
