Boston summers bring humidity and heat that challenge refrigeration systems. Prepare your Sub-Zero for the season with these steps.
Pre-Summer Maintenance
Clean Condenser Coils Critical before summer heat arrives: - Locate coils at top of unit (behind grille) - Use vacuum with brush attachment - Clean every surface thoroughly - This single step can prevent most summer failures
Verify Temperature Settings Standard recommendations: - Refrigerator: 38°F - Freezer: 0°F - Wine storage: 55°F (reds) / 45°F (whites)
Don't adjust colder for summer - the unit compensates automatically.
Check Door Seals Humidity increases seal stress: - Inspect gaskets for cracks - Test seal with paper test - Clean gasket grooves - Replace worn seals before summer
Summer Usage Tips
Entertaining Prep Before big gatherings: - Don't pack refrigerator too full - Allow air circulation between items - Pre-chill beverages the night before - Keep ice maker bin emptied regularly
Power Outage Preparation Summer storms cause outages: - Full freezer stays cold 48 hours - Half-full freezer lasts 24 hours - Consider frozen water bottles for backup cooling - Don't open doors unnecessarily during outage
Vacation Mode Going away for summer vacation: - Don't turn off the unit - Empty perishables - Set temperatures slightly warmer (40°F/5°F) - Clean interior before leaving
