Your walk-in cooler holds the heart of your business — produce, dairy, proteins and prepped food. When it stops cooling, the whole operation feels it. J and G Refrigeration repairs walk-in coolers for restaurants, grocers, caterers and food distributors across Rockford and Northern Illinois.
We work on the whole system: the evaporator inside the box, the condensing unit outside or on the roof, the controls, the doors and the panels. We find what's actually wrong and fix it.
Signs You Need Walk-In Cooler Repair
- Walk-in reads above 41°F
- Condensation or frost on walls, ceiling or product
- Door doesn't close on its own or gaps are visible
- Evaporator fans are noisy or not spinning
- Puddles under the evaporator
Common Problems We Fix
Box temperature climbing
Low refrigerant, a failing compressor or a dirty condenser coil are the most common causes.
Evaporator fans not running
Failed fan motors stop air movement and leave the coil iced or the box warm.
Door won't seal
Worn gaskets, sagging hinges and failed door closers let warm air in all day long.
Water on the floor
Clogged drain lines or overflowing drain pans create slip hazards and mold risk.
Condensing unit problems
Rooftop and outdoor units suffer from dirt, weather and worn electrical parts.
Our Process
- 1
Inspect the box
We check temperatures, door seals, panel condition and the evaporator coil.
- 2
Inspect the condensing unit
We check the outdoor or rooftop unit, condenser coil, fans and compressor.
- 3
Test controls and electrical
Thermostats, defrost controls, contactors and wiring are tested for proper operation.
- 4
Repair and confirm
We make the repair and verify the walk-in holds temperature before we leave.
Why Fast Response Matters
A walk-in cooler can hold thousands of dollars in product. Health codes require cold-holding at 41°F or below, so a cooler running warm is both a financial risk and a compliance problem. Call early — small issues are cheaper to fix than full breakdowns.
