How to Maintain Commercial Refrigeration Units, Honolulu, Hawaii

If you own or operate a small business that relies on commercial refrigeration, it’s essential to maintain each unit diligently. Whether you run a flower shop, a restaurant, or a grocery store, system failure could mean lost inventory, revenue, and customers. Fortunately, you can ensure each unit is always operating at full capacity by performing a few simple tasks periodically. 

3 Maintenance Tips for Commercial Refrigerators 

1. Clean the Condenser Coil 

As the condenser coil accumulates dirt, dust, and other debris, the entire unit becomes increasingly less efficient. When a refrigerator is constantly running at maximum power to maintain a consistent temperature, it’s prone to overheating and breaking down. That’s why most manufacturers recommend cleaning the condenser coil every 90 days.

After cutting power to the unit, use a stiff brush to dislodge large particles. Then use a vacuum with a soft-bristled brush attachment to remove the smaller particles. If the unit is located near a griddle or fryer, degreasing the coil may also be necessary.

2. Inspect the Gaskets

Since the fridge itself will outlast these rubber elements, inspect them periodically for signs of wear and tear. As soon as you notice a problem, call a commercial refrigeration contractor to replace them. 

3. Clear the Air Filters

The air filters are responsible for trapping grease, dust, and dirt. As they become coated in debris, the system’s ventilation becomes inhibited, forcing the refrigerator to work much harder than it should. Get in the habit of cleaning the filters every 30 to 90 days, and replace them entirely when they exhibit signs of wear, like cracks, chips, or sagging.
