Keeping Your Walk-In Cooler & Freezer Running

There are countless number of operations that could require a walk-in cooler or freezer - whether it be a restaurant, commercial kitchen, medical facility, gas station, or flower shop. The application of a walk-in unit is always the same though, and that is to provide a safe, climate controlled environment for whatever goods are being stored inside. Walk-in coolers and freezers should be viewed as an investment by business owners. Not only from a monetary standpoint, but also from the standpoint that it helps protect the contents that you are storing. Because of this reason you must ensure that your walk-in is running at tip-top effectiveness. Here are a few items to check in order to protect your investment.




The cooling components - coils, evaporators, fans, etc. - are what work to control the temperature and climate inside of your walk-in unit. Over time dust and debris can build up on these components so it is suggested that every few months you check the fans, coils, etc. for any build ups that may be occurring and thoroughly clean them. The dust and debris that builds up can cause components to struggle to keep up with regular demand and thus puts extra wear and tear on these components and any components that are part of the system. At least twice a year you should inspect and clean the condensing and evaporator coils as well as the fan to keep your unit running smoothly.




The walk-in door may be the most important part of your unit as it functions as the barrier keeping the cool air inside and the warm air from outside out of the unit. Even the tiniest of issues with a walk-in door not properly sealing could lead to damage and expensive repairs down the line, so it’s important to check every month or two for any signs of damage or wear. The door gaskets get plenty of wear and tear as it is used every time the door is open and closed, and the gaskets need to be replaced any time there are signs of ripping or tearing. On top of the regular use causing damage to the gaskets, they are also a prime spot for the growth of bacteria and mold, so regularly clean the door gasket when you can. If you see signs of damage, replace the gasket immediately. Similar to the door gasket, the door sweep at the bottom of the door is responsible for keeping the air-tight seal that is imperative to maintaining internal temperatures so if you see any damage or tears you should replace the door sweep as soon as possible. Lastly - check the door hinges. Most modern walk-in door hinges are equipped with a self-lubricating mechanism that keeps the hinges optimally lubricated, however standard door hinges may require yearly lubrication to ensure proper function. 




A tell-tale sign that you are having electrical issues with your walk-in cooler or freezer would be a spike in your electrical utility bill, or more obvious signs such as irregular temperatures or a buildup of moisture / ice inside of the unit itself. You can do a visual check of the electrical components and the connections to look for any signs of damage that may need to be repaired. If you can not see any issues, but still think something is wrong you should absolutely call a local electrocution to come check it out. Fixing the faulty electrical connections or damaged equipment will help save you money in the long run too as increased electrical bills and damage to other components will likely be significantly more expensive than a repair at the beginning of a problem. 




To keep ideal temperatures inside of the walk-in unit means that all excess moisture needs to be expelled from the unit itself. Excess moisture build ups are not only unsanitary, but they can lead to slip-and-fall accidents and damage to electrical components. One of the most common reasons for these moisture build ups are clogged drain lines. If you notice excess moisture then you should check and if needed - unclog - the drain line to ensure proper draining.
