8 Commercial Refrigeration Maintenance Tips for Restaurants

Commercial Refrigeration

Commercial refrigeration systems are one of the most important pieces of equipment in any restaurant. If your refrigeration system isn’t working at its optimum, you can end up with spoiled food, which can lead to costly repairs, lost revenue and unhappy customers. To avoid these problems, it’s important that you schedule regular inspections of your commercial refrigeration equipment. Here are some tips to help ensure that your kitchen equipment remains in good condition:

Keep it Clean

Keeping your commercial refrigerator clean is an important part of maintaining its efficiency. Most people think they only need to clean the inside of their commercial refrigeration unit, but that’s not true.

If you have a lot of condensation on your walls due to poor insulation or if there are any leaks in the system, then it can lead to mould and other unwanted bacteria growth. This will cause a foul smell and will make it difficult for you to keep food fresh when it should be healthy and safe for consumption by customers.

Get a fridge temperature monitoring app

There are many apps that can help you monitor the temperature of fridges and freezers in your commercial kitchen. One of them is Templogger, an app that allows you to track the temperature of fridges throughout the day. It’s easy to use, too: just open up the app on your phone or tablet and stick it into one end of a probe (the temperature sensor), then place another probe inside your fridge for about 12 hours. Once this time has elapsed, check out how cool or warm it was inside!

Check the Doors

There are 3 main things you should check. Firstly, Check the doors. Make sure that the door seals are still in place and that they aren’t damaged in any way. Secondly, check the hinges on a regular basis to make sure they’re not bent or broken. If you do find a problem, don’t hesitate to call in an expert for help. Finally, make sure that all of your refrigeration units are properly aligned with one another so there aren’t any gaps between them that could cause cold air loss into other areas of your restaurant building (like kitchens).

Fix Water Leaks Right Away

Water leaks can be dangerous and cause damage to your food items and flooring. Water leaks can also cause mould and mildew to grow, which is unhealthy for you and for customers. Water leaks can also cause fires if left unattended for a long period of time, which can result in significant financial losses for your business.

To prevent water damage from happening, fix any leak as soon as possible. This may require hiring an expert refrigeration repair company like [your company name] because they have the tools necessary to identify potential problems with your system before they become too big to fix on your own.

Log Temperatures

You can log your fridge’s temperatures with an app, or you can use a custom-made temperature logger. Either option will work well, but if you want to log other factors like humidity and door openings on top of the temperature, then it’s best to go with a custom-made option.

This way you can track not only what the temperature is in your equipment but also whether or not doors have been left open too long and ambient air temperatures outside of the kitchen area.

Maintain Your Cooler is a Cool Place for Food

The next item on our maintenance checklist is to ensure that your cooler is a cool place for food. While this may sound obvious, it’s important to maintain the recommended temperature at or below 40 degrees Fahrenheit. If you’re lucky enough to have a walk-in cooler, check the condenser coils regularly and clean them if they become dirty by using a wire brush or scraper. Also, check the drain line for any obstructions such as leaves or dirt.

Keep in mind that while there are several ways that refrigeration can fail, one of the most common culprits is damaged insulation because it allows hot air in and cold air out of your unit. To prevent this from happening, make sure you regularly inspect your unit for signs of damage or wear-and-tear (such as cracks) and replace parts when necessary (such as filters).

Keep Evaporator Coils Clean

Keeping your evaporator coils clean is essential in reducing energy costs and improving your refrigeration system’s performance. The coils are the part of the fridge that cools the air, so if they become dirty, they will not be able to cool effectively. To clean your evaporator coils:

  • Vacuum them

Use a soft brush attachment on a vacuum cleaner to remove dust and debris from around them. This should be done every 6 months or so depending on how often you use your unit and how many people are cleaning it in between times (if at all).

  • Use a coil brush

If you have stubborn build-up on the evaporator coil surface, use an abrasive coil brush to scrub off any deposits or buildup before vacuuming again with the soft brush attachment.

Follow Manufacturer’s Guidelines

You should follow the manufacturer’s guidelines. It’s that simple. If your restaurant uses commercial refrigeration equipment, then you can’t risk skipping over this step. You must adhere to the manufacturer’s recommendations for cleaning and maintenance if you want to ensure that your equipment performs at its best.


Refrigeration maintenance is a critical part of running a restaurant, but it doesn’t have to be overwhelming. Just focus on keeping your equipment clean and following the manufacturer’s guidelines. If you do that, then everything else will fall into place.
