Do you repair Sub-Zero built-in refrigerators?
Yes. We diagnose airflow, sealed system, defrost and electronic control issues in Sub-Zero built-in refrigeration systems depending on model and condition.

My Sub-Zero refrigerator is warm but the freezer works — what could it be?
This may indicate airflow restriction, evaporator fan malfunction, defrost failure, sensor problem or sealed system imbalance. Proper diagnostic testing is required.

Is Sub-Zero repair worth it?
In most cases, yes. Sub-Zero units are premium investments designed for long service life. Professional repair is typically more cost-effective than replacement.
