Heise's Plumbing performed high-end Sub-Zero built-in refrigerator repair for a residence in Pacific Heights, San Francisco, CA. The homeowner noticed rising temperatures in the fresh food compartment and frost accumulation on the back panel. Our master appliance repair technicians diagnosed a failing sealed system compressor and restricted evaporator fan assembly. We recovered refrigerant according to EPA guidelines, installed a genuine Sub-Zero compressor replacement, replaced sealed filter driers, vacuumed the system, and recharged R-134a refrigerant to exact factory specifications. Operating temperatures were calibrated and verified for optimal cooling performance.
The Problem
Sub-Zero built-in refrigerator failing to maintain set temperature due to sealed system compressor degradation.
Our Solution
Replaced compressor, filter drier, and evaporator fan assembly using factory-authorized Sub-Zero parts.
