Refrigeration Warning Signs

Refrigeration systems play a vital role in the operations of a commercial business. Whether that’s a restaurant, grocery store, cafeteria, or pub. Refrigeration systems are pivotal in preserving the freshness and quality of food items. Given their critical role it is essential to remain vigilant for any signals that call for the expertise of a professional. In this blog post, we will share some of these warning signs so that you can address any possible refrigeration issues promptly and mitigate the risk of incurring costly repairs later on. 

Inconsistent Temperature

If you notice inconsistent temperatures in your commercial refrigerator this could indicate a few things. One, your thermostat may be malfunctioning. Two, your refrigerator might have compressor issues. Three, there might be inadequate airflow. It’s highly important that if you notice inconsistent temperatures you seek professional help. Ignoring this sign could affect the freshness and quality of your perishable foods. 

Excessive Ice Buildup

If you start to notice excessive frost buildup in your refrigeration unit it’s important you seek out professional help. Too much ice buildup can indicate that the automatic defrost system is malfunctioning and needs to be looked at by a technician. 

Loud Noises

Refrigeration systems are completely silent but they also should not be making any loud noises. If you notice excessive or unusual noises this is another indicator that something is not right. Some common noises that indicate mechanical issues could be buzzing, rattling, or clunking. In order to prevent any further damage to your refrigeration system address this issue promptly. 


A more obvious indicator that should automatically raise concern is any water leaks. Water leaks can happen because of clogged drain lines, damaged seals, defrost system malfunctions, and many other factors. For the sake of preventing higher costs later on and for the safety of employees and customers from slippery floors make sure you call a technician immediately. 

High Energy Bills

If you notice your energy bill has increased from the previous months this should be a warning sign that something is not right with your refrigeration system. Malfunctioning components in your refrigerator can lead to higher energy consumption thus increasing your energy bill. 

For example, if your evaporator fans are not functioning properly it can cause your thermostat to work harder increasing your bill at the end of the month. To elaborate in more detail, evaporator fans basically circulate air in your refrigerator to maintain consistent temperatures. If these fans don’t work properly it can cause areas of your refrigerator to become warmer. This will cause your thermostat to work harder by cooling more. 

Similarly, if your refrigeration system seals are damaged or not properly sealed this could cause cold air to escape and warm air to come in. The thermostat will then be triggered to signal the cooling system to run to get back to the desired temperature that was lost due to the seals. Again, this increases your energy bills. 

These are just two examples of malfunctions in your refrigerator that can cause high energy bills. Of course, there are many other possible malfunctions but the main point is to call a technician if you notice any significant changes in your energy bills.
