Walk-in Cooler and Freezer Care in the Hot Summer Months

By July 12, 2023Uncategorized
If you own or operate a U.S. Cooler walk-in cooler or freezer, you know how important it is to keep it running smoothly and efficiently, especially during the hot summer months. High temperatures and humidity can put extra stress on your refrigeration system and affect the quality of your stored products. Here are some tips on how to care for your U.S. Cooler walk-in cooler or freezer during the summer season.

Gaskets and Hinges

Check the door gaskets and hinges regularly for any signs of wear or damage. A loose or broken gasket can let warm air enter the walk-in, causing ice buildup and higher energy consumption. A faulty hinge can prevent the door from closing properly, creating a similar problem. Replace any defective parts as soon as possible to maintain a tight seal.

Condenser Coil and Fan Blades

Clean the condenser coil and fan blades at least once a month, or more often if needed. Dust, dirt, grease and debris can accumulate on these components, reducing their efficiency and performance. A dirty condenser coil can also overheat and damage the compressor, leading to costly repairs or replacement. Use a soft brush or vacuum cleaner to remove any dirt from the coil and fan blades, and wipe them with a damp cloth.

Temperature and Humidity

Monitor the temperature and humidity inside the walk-in regularly, and adjust the thermostat accordingly. The ideal temperature range for a walk-in cooler is between 35°F and 41°F, while for a walk-in freezer it is between -10°F and 0°F. The ideal relative humidity level is between 50% and 60%. If the temperature or humidity is too high or too low, it can affect the quality and shelf life of your products, as well as increase the risk of mold and bacteria growth.


Avoid overloading or underloading your walk-in cooler or freezer. Overloading can block the airflow and reduce the cooling efficiency, while underloading can cause the compressor to cycle on and off more frequently, wasting energy and shortening its lifespan. Try to keep your walk-in at least 75% full, but not more than 90% full, and arrange your products in a way that allows for proper air circulation.

Routine Maintenance

Schedule regular maintenance and inspections by a qualified technician. A professional can check your refrigeration system for any potential issues or problems, such as leaks, cracks, corrosion, loose connections, low refrigerant levels, etc. They can also perform any necessary repairs or adjustments to ensure optimal performance and safety. Ideally, you should have your walk-in cooler or freezer serviced at least twice a year, before and after the summer season.
