Toronto Commercial HVAC repairs walk-in coolers for restaurants, grocery stores, convenience stores, catering kitchens, breweries and food distributors across Toronto and the GTA. Our 313A licensed mechanics carry Heatcraft, Russell, Bohn and Copeland parts and answer walk-in failures on a 24-hour priority line.
Walk-in coolers usually fail for four reasons. Refrigerant leaks at flare fittings, valves and coil joints slowly drain capacity. Condenser coils load with grease, lint and dust until head pressure climbs and the compressor overheats. Defrost or airflow problems ice up the evaporator. Torn door gaskets and worn closers let warm, humid air in all day, so the system never catches up.
Repairs typically cost $450 to $3,200, plus a $225 refrigeration diagnostic. Every repair ends with a temperature log back to setpoint.

When to Call for Walk-In Cooler Repair

- Ice building on the evaporator.
- Water pooling on the floor.
- Door not closing or sealing.
- Unusual noises from the condensing unit.
Repair or Replace the Condensing Unit?
Most walk-in repairs are well worth doing. If a condensing unit past 12-15 years loses its compressor, or the system uses a phased-out refrigerant and has a major leak, a new condensing unit is often the better buy. We quote both in writing. Freezer-specific problems are covered on walk-in freezer repair.
