Heise's Plumbing recently completed a professional Sub-Zero fridge repair and temperature adjustment at an estate in the Lindenwood neighborhood of Atherton, California. The homeowner reported that their built-in Sub-Zero refrigerator was starting to frost up and fail to maintain cool temperatures. Our technician inspected the cooling loop and diagnosed a severe build-up of ice on the evaporator coils, restricting critical airflow. We defrosted the evaporator coils and removed all excess ice blockages. To prevent future build-ups, we adjusted the temperature settings from 38°F to 35°F, reducing constant compressor cycles. The appliance was thoroughly tested, and all operations were verified for safe, reliable, and energy-efficient cooling in compliance with plumbing guidelines.
