Commercial Refrigeration Repair

Repairs for display cases and walk-ins

Trust Cooling repairs the commercial refrigeration that food businesses rely on: multidecks, serve-over counters, glass-door coolers and freezers, island freezers, bakery and ice cream cases, and walk-in coolers and freezers. Our technicians are the same team that designs and installs equipment for supermarkets, restaurants, butchers and bakeries across the Greater Toronto Area, so they know how these systems are put together and how they fail.

Refrigeration does not keep office hours. Our regular hours are for planning and routine work, but emergency support is available 24/7. If a freezer is warming up on a long weekend or a walk-in stops cooling at night, call +1 647-719-3171.

Signs something is wrong

Many refrigeration failures give a warning before they become an emergency. Call us if you notice any of these:

• Case or walk-in temperatures creeping up, even by a couple of degrees
• Ice building up on the evaporator coil, or frost on product and shelving
• Water pooling under a case or on the walk-in floor
• A compressor that runs constantly or short-cycles on and off
• New noises such as rattling, grinding or a fan that has gone quiet
• Door gaskets that are torn or no longer seal, or doors that will not close properly
• Condensation or fog on glass doors that does not clear
• Alarms from your temperature monitoring system

Catching these early usually means a smaller repair, less stock thrown away and a lower bill.

Common causes of failure

Most of the calls we see come down to a handful of causes. Dirty condenser coils are the most common: dust, grease and flour stop the system from rejecting heat, so the compressor works harder and the case warms up. Evaporator fan motors wear out and stop moving cold air. Defrost problems let ice build up until it blocks airflow. Blocked drain lines cause leaks and ice. Worn door gaskets let warm air in all day. Less often it is a refrigerant leak, a failed controller or sensor, an electrical fault or a compressor problem.

A technician will diagnose the actual cause before replacing parts. That matters, because a compressor replaced to fix what was really a dirty coil will fail again.

What to do while you wait

If equipment stops cooling, a few simple steps can protect your stock until help arrives:

• Keep doors closed. A closed walk-in or freezer will hold temperature far longer than you might expect. Plan each trip in and out.
• Check the obvious. Has a breaker tripped? Is the unit switched on? Has the thermostat been changed? Is something blocking the vents inside or the condenser outside?
• Move high-risk product. If you have space in another cooler or freezer, move meat, dairy and seafood first.
• Record temperatures. Note the time and temperature every so often. It helps the technician and gives you a record for food safety decisions.
• Do not keep resetting the unit. Repeatedly restarting a compressor that is struggling can make the damage worse.

Remember that Ontario requires potentially hazardous food to be held at 4°C or colder. If product has been above that temperature for a long time, check with your local public health unit about whether it is safe to keep.

How a repair call works

When you call, we will ask what equipment is affected, the make and model if you have it, the current temperature and what you have noticed. That helps us bring the right tools and likely parts. On site, the technician diagnoses the fault, explains what is wrong and what the options are, and gets your equipment running again. If a part has to be ordered, we will tell you how long that will take and whether a temporary fix can keep you running in the meantime.

Sometimes equipment has reached the point where repair no longer makes sense, because parts are hard to find, the refrigerant is being phased out, or energy costs are much higher than a new unit would be. When that is the case, we will say so honestly and explain the replacement options. Financing through our partner EconoLease can help if a replacement was not in the budget.

Prevent the next breakdown

Most emergency calls could have been avoided with regular maintenance. Once your equipment is running again, ask us about planned preventive maintenance, which keeps coils clean, drains clear and small faults from turning into emergencies.
