Extended absences from your Naperville home require specific preparation for your Sub-Zero refrigeration equipment. Whether you are leaving for a winter vacation, spending summer at a second home, or traveling for an extended business trip, proper preparation protects your appliance investment and prevents potential water damage or food safety issues. This checklist is organized by departure timeline.
One week before departure, take inventory of refrigerator and freezer contents. Consume or donate perishable items that will expire during your absence. For absences longer than two weeks, consider reducing refrigerator temperature to its lowest setting to maintain food safety with reduced door-opening frequency. Freezer contents are generally safe for the duration of most vacations if the freezer remains operational and the door stays closed.
Two to three days before departure, clean the interior of both refrigerator and freezer compartments. Remove any items that could leak or spill during your absence. Wipe down shelves and bins with a mild cleaning solution. Check the ice bin - for absences longer than one week, we recommend emptying the ice bin and turning off the ice maker to prevent ice clumping and potential water system issues.
On departure day, verify the unit is operating normally by checking temperature displays against setpoints. Ensure the condenser area is clear of any debris that might restrict airflow during your absence. If you have a water-connected model, consider turning off the water supply valve as a precaution against potential water line issues. Do not unplug or turn off the unit unless you have completely emptied it - running the unit empty is preferable to allowing interior temperatures to rise and then re-cooling.
For extended absences of 30+ days, we recommend scheduling a professional maintenance visit before departure. This ensures your unit is operating at peak efficiency while unattended, identifies any developing issues that could fail during your absence, and documents the unit's current condition.
