Commercial refrigerators are designed to operate at higher temperatures than your home model, so it’s necessary to clean out the condenser coils regularly. If these surfaces get dirty or dusty they can create an insulating layer which causes them to retain heat and lead to overheating as well as component failure. A good way to clean and remove build-up debris is by using an air compressor, a small brush, a small coil comb to realign evaporator fins, and a coil cleaner.
Performance varies depending upon size and type, but most models require cleaning about every three months. Some manufacturers recommend more frequent service while others state once per year should suffice if cleaned regularly.
As the condenser coil, your evaporator’s job is to absorb heat as warm air passes through and help cool down commercial refrigeration equipment. Failure to keep the evaporator coils clean or clear from blockage can result in your equipment underperforming or even overperforming meaning higher electricity costs. The evaporator coil should be inspected every time maintenance is scheduled.
You can increase airflow by using a small evaporator comb to realign fans and remove excess grease and grime with a powerful coil cleaner. Cleaning this coil is especially important if your refrigeration equipment is located near cooking equipment such as fryers or grills.
