Walk-in Freezer Repair in the San Francisco Bay Area

A walk-in freezer failure can cost a business thousands of dollars in spoiled product before anyone notices the temperature climbing. Best Pro repairs walk-in freezers for restaurants, markets, ice cream shops, commissaries and food producers.

Typical walk-in freezer failures

• Defrost problems. When a defrost heater, timer or termination thermostat fails, ice builds up on the evaporator coil until the fans are blowing through a block of ice.
• Frozen drain lines. The drain line needs its own heater. When it fails, defrost water freezes in the pan and the line, and the ice spreads.
• Door frame heaters. A burned-out heater lets the door freeze to the frame, and a door forced open every morning soon stops sealing.
• Overheating compressors. A dirty condenser coil, a weak fan motor or a condensing unit in a hot, cramped space — common in San Francisco basements and on rooftops exposed to salt air.
• Low refrigerant. A slow leak shows up as a box that takes longer and longer to pull down after deliveries.

Our technicians check the complete system and fix the cause, not just the symptom.

Combination boxes

Many restaurants run a cooler and a freezer in one box, with the freezer section behind the cooler. Each side has its own evaporator and controls, but a problem in one — a door left open, a clogged drain — often shows up in the other. We check both.
