Tips for Keeping Your Commercial Refrigerator Running Smoothly and Efficiently

Posted by on 5/9/2023

Commercial refrigerators are one of the essential appliances for any food business, because they allow you to keep your ingredients fresh and your customers happy. However, like any other appliance, they also require regular maintenance to ensure optimal performance and prevent breakdowns. 

With proper maintenance, commercial freezers can consume more energy, operate less efficiently, and even succeed in keeping food at the appropriate temperature.

In this blog, we will discuss some important tips on maintaining your commercial refrigerator to keep it running smoothly and efficiently, ensuring the longevity of your investment and the safety of your food products.

  1. Regularly clean the condenser coil.

The condenser coil in your commercial freezer must be cleaned. Most manufacturers advise cleaning them every three months. It may be difficult to regulate the temperature if it is dirty or dusty, which could lead to overheating and component failure.

The coil is close to the condenser of the apparatus. You should remove the unit's power before cleaning it with a stiff-bristled brush. After that, use an air compressor or powerful vacuum to remove any leftover debris. 

For more specific instructions, refer to your equipment manual or guide on cleaning condenser coils.

  1. Check the area by the evaporator coil.

Like the condenser coil, the evaporator coil is essential to your commercial refrigerator. The evaporator coil, which is situated next to the evaporator fan, collects heat when warm air flows through the refrigeration system, assisting in cooling the appliance's interior.

Keep the space around the coil tidy and free of obstructions. You should also avoid packing the interior tightly with numerous goods, especially if they are quite hot. The coil may freeze if the unit's vents block airflow, which could result in water leaks and an increase in cabinet temperature.

  1. Check the air filters often.

The air filters in your refrigerator might also get clogged up with grease and grit. Regular cleanings are crucial since a significant buildup might make it difficult for the air in the unit to ventilate properly.

Always use a strong shop vacuum to remove any dust or lost debris and a degreasing solution to eliminate any heavy grease.The air filter might be harmed by excessive grease and dust. Make sure to replace the filter right away if you see splits in the debris.

  1. Routinely clean drain pans and tubes.

Large-scale accumulations of sludge and slime might cause your unit to freeze in a commercial refrigerator. A foul smell may be released into your kitchen area if your drain pipe is overflowing with moisture and muck. 

Therefore, remember to add the drain pans and tubing to your checklist. Apart from this, also look for points such as:

  • Always check your drain pan and any tubing that can frequently accumulate debris.

  • At least once a month, wash the pan with soap and warm water or vinegar.

  • To avoid a serious blockage, examine the tubing every few months.

  1. Keep your refrigerator unit dry.

Make sure to clean up any liquid that gathers on your reach-in unit's surface or shelving. Your commercial freezer may eventually freeze up if too much moisture is present. Not only should spills be cleaned up right away, but you should also check for moisture buildups at least once a week.

The same maintenance routine applies to a walk-in unit. Your fridge's floors can be dehumidified to prevent slipping and falling incidents.


By implementing the tips and techniques discussed in this blog, you can easily prevent costly breakdowns, minimize energy consumption, and ensure the safety and quality of your food products. 

Remember to schedule regular inspections and cleanings, monitor temperatures, check seals and hinges, and maintain proper ventilation to keep your commercial refrigerator in optimal condition.
