Your Sub-Zero refrigerator is a significant investment that can last 20+ years with proper care. Here's how Boston homeowners can maintain their units for optimal performance.
Clean the Condenser Coils
Sub-Zero recommends cleaning condenser coils every 6-12 months. In the Boston area, with dust and pet dander common in older homes, consider cleaning every 6 months. The condenser is typically located at the top of the unit behind the grille.
Check Door Seals
New England's humidity fluctuations can affect door gaskets over time. Test your seals by closing the door on a dollar bill - if it slides out easily, the seal may need replacement.
Monitor Temperature Settings
Sub-Zero refrigerators should maintain 38°F in the refrigerator and 0°F in the freezer. Boston's seasonal temperature changes mean your unit works harder in summer - ensure settings remain consistent.
Replace Water Filters
For units with ice makers and water dispensers, replace the water filter every 6-12 months. Greater Boston's water quality varies by municipality, affecting filter lifespan.
Schedule Professional Service
Even with diligent maintenance, annual professional inspection ensures optimal performance. Our certified technicians can identify potential issues before they become costly repairs.
