In order for your commercial refrigerator to keep your food and other items cold, it has to have ample coolant. Every now and then -- depending on the type of refrigeration system that you have and how heavily it is used -- it will need to be refilled with more coolant. Luckily, a contractor who has experience working with commercial refrigeration systems can help. These are a few signs that the coolant in your refrigerator is too low, which may warrant a visit from a refrigeration specialist.
1. It's Noisy
Your refrigeration system should be relatively quiet, other than an occasional humming noise from its components running. If you start to notice strange noises, such as hissing noises, it could be related to the refrigeration coolant levels. Basically, the system could be trying to use coolant that it doesn't have. Regardless, you'll need to have a professional come out to determine the source of the problem.
2. The Temperatures are Fluctuating
If you have noticed that the temperature seems to be fluctuating in your refrigeration system, such as if the temperature gauge always shows a different temperature or if you notice ice forming, then it could be due to a lack of coolant. This can happen when you have barely enough coolant to keep the unit cold; when you open the door, the system is not able to keep up with the change in temperature. Adding coolant should help with this problem, or your refrigeration repair professional can get to the bottom of the issue.
3. There's a Strange Smell
As your system starts to run out of coolant, you can expect the system itself to let out a rather sour, strange smell. Also, a lack of coolant can also cause food to spoil too early, which can also obviously cause unpleasant odors. Never ignore an unpleasant smell in your commercial refrigeration system, or you could find yourself dealing with even worse issues.
As you can see, there are a few signs that you can look out for to determine whether or not your commercial refrigeration system is in need of more coolant. If you are still unsure, or if you think that something else might be wrong with your unit, a professional can add more coolant and check for other issues.
