A restaurant business relies heavily on refrigeration systems. Without it, uncooked meat and fresh vegetables will rot, beverages and alcohol will be warm and customers will leave. It's almost impossible to run a restaurant without a properly working refrigeration system.

Common Problems:

  • Frost or ice develops: This may be a sign of poor airflow, or a refrigerant leak.
  • Can't maintain temperature: Could be a simple user error, malfunctioning thermostat, bad seals on doors, compressor issue, or, again, a refrigerant leak.
  • Loud noises: There are fans, motors, compressor, and other mechanical component in a refrigeration equipment. Expect to hear noises; however, if it's a noise that's unfamiliar,schedule service with your refrigeration contractor.

When it comes to maintenance, think of your commercial refrigerator like you would your car. Imagine the compressor in a cooler is like an engine in a vehicle. If the compressor goes bad and is replaced you get a new compressor, not a whole new cooler. The same way the garage doesn’t tell you to get a new car just because you need a bit of engine work. In other words, all the other components including coils, fans, controls, piping, and gaskets (door seals) are still old. This is similar to an engine in a car going bad and being replaced. You end up with a new engine in an old car. There are a couple of key factors to consider when trying to decide whether or not to do a major repair on a piece of refrigeration equipment. Here are a few things to ponder before pulling the trigger on an expensive repair.
