Even if now isn’t the right time for you to upgrade to Energy Star refrigeration, there are some things you can do to be sure your current refrigeration is running at peak efficiency.  Something as seemingly minor as a slightly tilted cabinet can be a source of lost energy.  That’s because the doors may not close properly and could allow chilled air to escape.  True is one of the top refrigeration manufacturers in the world and the True website has a nice page of owner maintenance videos.  One of their short videos addresses this issue; True suggests checking the level from left to right and front to back, and then adding shims to the casters to achieve the perfect level you need.

Besides keeping your cabinet level, True also suggests cleaning the condenser regularly to keep it running efficiently.  Proper upkeep like this can greatly extend the life of your commercial refrigerator and can help you keep those energy bills more reasonable.
