When a commercial cooler or freezer stops holding temperature, every hour counts. J and G Refrigeration repairs commercial refrigeration equipment for restaurants, grocery stores, convenience stores and warehouses across Rockford and Northern Illinois — day or night, weekends and holidays included.
We are a small, owner-operated company. That means the person who answers your call is the person who cares about getting your equipment running again. We diagnose the real cause, explain it in plain language, and fix it right so you are not calling again next week.
Signs You Need Commercial Refrigeration Repair
- Product feels warmer than normal or thermometers read above 41°F
- The unit runs constantly and never seems to shut off
- Your energy bill jumped without a change in business
- Frost or ice is forming where it shouldn't
- Door gaskets are torn or doors don't seal tight
Common Problems We Fix
Unit running but not cooling
Usually a refrigerant leak, a failing compressor, a bad condenser fan motor or a dirty condenser coil that can't reject heat.
Compressor short-cycling
Turning on and off rapidly wears out the compressor. Common causes include low charge, bad controls or an oversized or failing start component.
Ice building up on the evaporator
Defrost heaters, timers or termination switches fail and the coil freezes solid, blocking airflow.
Water leaking on the floor
Clogged or frozen drain lines and failed drain heaters create slip hazards and health code problems.
Loud or unusual noises
Grinding, rattling or squealing often point to fan motors, worn bearings or loose mounting hardware.

A failed cooler can cost thousands of dollars in spoiled inventory within a few hours, and food held above 41°F puts you at risk with the health inspector. Fast response protects your product, your customers and your reputation. That's why we keep our phone on 24/7.
