Walk in Cooler/ Freezer Maintenance

Walk-in coolers are a big investment. As the containment unit of the majority of your frozen and chilled goods, it’s vital to make sure your unit stays up and running. If properly taken care of, they can serve you for years due to their reliability and durability. Below is a list of key things you can do to ensure your walk-in cooler serves you year-round.



First and foremost, it’s important to make sure your cooler’s door is being kept close. This sounds obvious, but in order to keep cold from escaping, it’s best to ensure that the door isn’t being propped open for long periods of time, and is being latched completely close when not in use. Because a walk-in cooler’s cooling system only kicks on when it needs to maintain the set temperature, the less cold air escaping when opening the door, the better. According to an article from kpsglobal.com, even leaving the door open for longer than just five seconds can affect the cooler’s system cycle, and in turn cost you more money on your electric bill. Minimizing time spent with the door open will save you money in the long term.

Secondly, you’ll want to make sure you’re checking and cleaning your condensing unit periodically. A condensing coil should be checked and cleaned a minimum of twice a year. As the heart of your walk in, making sure the condensing unit is working properly will ensure constant cold air flow through the walk in when needed. It’s also important to make sure nothing is blocking the unit, as this will restrict air flow, potentially causing your unit to work harder than it needs to. Keeping your unit free of obstruction will keep your unit running optimally.

Additionally, it never hurts to have a technician come in and check the electrical wiring of your cooler. Keeping an eye out for frayed or damaged wiring can prevent electrical problems going unnoticed for long periods of time. Damaged wiring can cause for high amperage, meaning your unit will be drawing more electricity than necessary with proper wiring, leaving you with a higher electrical bill and an overworked cooling unit. It’s also a good idea to compare the walk-in’s thermostat with a second thermometer from time to time. If the thermostat is off, you may be setting the internal temperature higher or lower than you realize.

Lastly, know what to look for when giving your walk-in an inspection. Corrosion, oil stains, and leaks in any tubing or pipes are all indicators in might be time to have your cooler looked at. It also never hurts to occasionally check the drain pain. It’s important to make sure the drain pan hasn’t overflowed with any obstructions or ice buildup.
