A refrigerated display case is one of the most important pieces of equipment in any grocery store, convenience store, or food business. It keeps your products fresh, appealing, and safe for customers. But like any machine, it won’t last forever—especially if it isn’t well maintained.
If you’ve noticed your case isn’t cooling as efficiently as before, or your energy bills are creeping up, it might be time to rethink your maintenance routine.
Here are some practical tips to help you get the most out of your refrigerated display case.
Keep Coils Clean for Maximum Efficiency
Your refrigerated display case relies on condenser and evaporator coils to maintain the right temperature. Over time, dust and debris build up on these coils, making the system work harder to cool your products. When that happens, your case uses more energy and becomes less efficient.
To prevent this, clean the coils regularly—at least once a month. Use a soft brush or a vacuum with a brush attachment to remove dirt and dust. If the buildup is heavy, you can use a coil cleaner recommended by the manufacturer.
Check and Replace Hussmann Case Parts as Needed
Even with regular cleaning, parts of your display case will wear out over time. Gaskets, fans, thermostats, and other small components play a crucial role in keeping the unit running smoothly. If any of these parts fail, your case may not cool properly, leading to spoiled products and higher operating costs.
If you notice inconsistent temperatures or hear unusual noises, it might be time to inspect the internal components. Swapping out worn-out parts with high-quality Hussmann case parts can improve efficiency and prolong the life of your display case.
Keep the Airflow Unobstructed
Good airflow is essential for keeping your refrigerated display case operating efficiently. When air circulation is blocked, certain areas inside the case can become warmer than others, leading to uneven cooling.
To maintain proper airflow, avoid overloading the shelves with too many products. Leave some space between items so air can circulate freely. Also, make sure that nothing is blocking the case’s vents or fans. Regularly check for obstructions and adjust product placement as needed to ensure even cooling throughout the unit.
Inspect Door Seals for Leaks
The rubber gaskets around the doors of your refrigerated display case help keep cold air inside. Over time, these seals can wear out, crack, or loosen, allowing warm air to seep in. When that happens, your unit has to work much harder to maintain the correct temperature, leading to higher energy bills and unnecessary strain on the compressor.
To test your door seals, close a piece of paper in the door and try to pull it out. If it slides out easily, the gasket isn’t sealing properly. Replacing worn-out seals can make a big difference in energy efficiency and help maintain consistent cooling.
Monitor Temperature Settings
It’s easy to assume that your display case is cooling at the right temperature, but small fluctuations can affect product quality. If the temperature is too low, it wastes energy and may cause unnecessary frost buildup. If it’s too high, perishable items can spoil faster.
Check the thermostat regularly and ensure it’s set to the manufacturer’s recommended temperature. If you notice that the case isn’t maintaining the right temperature, the thermostat may need to be recalibrated or replaced.
