Preparing Your Sub-Zero Refrigerator for Arizona Summer

Arizona summers test even the finest refrigeration equipment. When temperatures regularly exceed 110 degrees Fahrenheit, your Sub-Zero refrigerator works overtime to maintain the precise temperatures that preserve your food and protect your investment.

Start your summer preparation by cleaning the condenser coils. Desert dust accumulates quickly in Arizona, and dirty coils force your compressor to work harder. Locate the coils behind the kick plate at the bottom of your refrigerator and use a vacuum with a brush attachment to remove accumulated dust and debris.

Check your door seals carefully. Arizona's low humidity causes rubber gaskets to dry out and crack faster than in more humid climates. Run your finger along the entire seal perimeter, feeling for gaps or hardened sections. A dollar bill test works well: close the door on a bill, and if it slides out easily, your seals need attention.

Verify that your refrigerator has adequate ventilation clearance. Sub-Zero units need proper airflow around the condenser to dissipate heat effectively. Ensure nothing is blocking the front grille and that there is appropriate clearance on the sides if your unit is built-in.

Consider the ambient temperature in your kitchen. If your refrigerator is near a window receiving direct sunlight or next to your range, the additional heat load increases during summer. Window treatments or strategic appliance placement can reduce this stress.

Schedule professional maintenance before summer arrives. Our technicians can check refrigerant levels, test thermostat accuracy, inspect the evaporator fan, and identify potential issues before they become failures during the hottest months.
