Commercial Freezer Repair in the San Francisco Bay Area

A commercial freezer that warms up can ruin a lot of inventory in a few hours — ice cream, dumplings, prepped proteins, a weekend’s worth of fries. Best Pro repairs reach-in, undercounter, chest and display freezers for restaurants, ice cream shops, markets and convenience stores.

Typical freezer failures

Freezers fail differently from refrigerators, and most service calls come down to the defrost system. When a defrost heater, timer, termination sensor or control fails, ice builds up on the evaporator coil until cold air can no longer get through. The freezer warms up even though the compressor never stops.

Other common causes:

• Torn door gaskets or failed door heaters that let warm, humid air in and frost the door frame.
• Frozen drain lines that turn the defrost water into a sheet of ice inside the cabinet or a puddle under it.
• Fan motors on the evaporator or condenser that slow down or stop.
• Overheating compressors with a clogged condenser coil, especially in cramped back rooms and storefronts without much airflow.

Display freezers in storefronts

Glass-door merchandisers in markets and corner stores often sit near a front window. Afternoon sun on the glass, a door opened every few minutes and a condenser pushed against the wall make a tough combination. We check placement and airflow along with the parts.

What we do

• Diagnose the complete system and fix the cause, not only the symptom
• Repair or replace defrost heaters, timers, sensors and controllers
• Replace door gaskets, hinges and door heaters
• Service condenser and evaporator fans and compressors
