How often should I schedule Sub-Zero maintenance?

We recommend twice yearly, ideally in spring and fall. This prepares your unit for the seasonal extremes common along the North Shore.

Does preventive maintenance really prevent repairs?

Yes. Regular maintenance catches small issues before they become expensive repairs. Condenser cleaning alone prevents the most common performance problems.

What does a typical maintenance visit include?

A thorough inspection of all components, condenser coil cleaning, door seal check, temperature calibration, drainage verification, and a written condition report.

Preventive Maintenance

The changing seasons along Lake Michigan bring beauty and unique environmental challenges. Your Sub-Zero was built to last, but thoughtful preventive care extends its life and preserves its performance. Our maintenance program is designed specifically for the North Shore climate.

Our seasonal maintenance includes condenser cleaning, door seal inspection, temperature calibration, and component assessment.

Spring and fall are ideal times for maintenance visits, preparing your unit for the humidity of summer and the dry cold of winter.

Regular maintenance can prevent up to 80 percent of common repair issues and helps maintain energy efficiency.

We provide a written report after each visit with our findings and recommendations for your records.
