I’m Mitch Byrne. I have been working in the Refrigeration Trade for over 16 years. I know from experience that commercial refrigeration maintenance can extend equipment life by years & save big on electrical consumption. This article will explain the importance of Commercial Refrigeration Maintenance. It will also outline basic DIY Maintenance as well as professional clean & checks done by a contractor. It is possible for equipment owners to perform some basic maintenance tasks between contractor visits.
Commercial Refrigeration Maintenance is critical, especially when it comes to Walk-In Coolers, Freezers & Ice Machines. This is especially true when it comes to line coolers. All refrigeration needs to expel heat. The majority of units do this through an air cooled condenser coil. This is done by drawing air through the coil. This causes dust & debris to form fairly quickly on the condenser coil. Failure to clean condenser coils on a regular basis will increase electrical consumption & lead to major system component failure such as burnt wiring, a failed condenser fan motor, a restricted metering device or a failed compressor. These are some, but not all of the possible consequences of lack of maintenance. Without a doubt poor maintenance will decrease the lifespan of equipment & increase electrical consumption.
There are things you can do between contractor clean & checks that can really help. The following is a checklist of tasks you can perform to help extend the life of your commercial refrigeration equipment.
- Visually inspect the condenser coil on self contained refrigeration. Often the condenser coil is behind a cover at the top or bottom of commercial coolers & freezers. Condenser coils can also be located at front right or left on a unit & also at the back of a unit. The condenser cover can usually be removed with a Philips screw driver. Occasionally a ¼” or 5/16” nut driver is needed to remove cover. Pictured are a couple types of coolers & condensers.
