Frequently Asked Questions

Here you'll find answers to the most common questions about Sub-Zero appliance repair and maintenance.

How often should a Sub-Zero be serviced?
We recommend professional maintenance for your Sub-Zero every 1-2 years. This includes cleaning the condenser coils, checking the seal system, calibrating thermostats, and diagnosing electronics. Regular service helps prevent major breakdowns and extends the appliance's life.
What should I do if my Sub-Zero is not cooling?
First, check the thermostat settings and ensure the door is closed tightly. Clean the condenser coils of any dust. If this doesn't help, the problem could be more serious, such as a refrigerant leak or a faulty compressor or fan. In that case, contact us immediately for a diagnosis.
What is the most common repair you perform?
We most frequently address issues with cooling systems (clogged coils, faulty fans), broken ice makers, and worn-out door seals. We also regularly solve electronic problems, especially after power surges.
How much does a Sub-Zero diagnostic cost?
We believe in transparent pricing. We have a flat fee for the service call and diagnosis. If you decide to proceed with the repair with us, this diagnostic fee is typically waived and included in the total repair cost. We always provide a full quote before any work begins.
Which Sub-Zero models do you repair?
Our experienced Sub-Zero repair specialists work on all models, old and new. We service Classic (Built-In) Series, PRO Series, Designer (Integrated) Series, wine storage units, and undercounter models. We are familiar with all Sub-Zero configurations.

Yes, absolutely. We provide a warranty on all parts and labor. The length of the warranty depends on the type of repair. We want you to have complete confidence in the quality of our service.
