Your commercial kitchen's walk-in freezer, such as your used stainless steel three-door freezer, depends on a specific level of freon to keep the system cold. This refrigerant is stored in a closed system that circulates through a motor as necessary to cool the contents. Unfortunately, those systems can develop leaks that drop the refrigerant levels and cause the freezer to struggle with maintaining temperature. Since this can be costly in inventory loss, you need to be attentive to the potential for freon leaks. This is particularly true if you buy a used freezer because of its past hours of use. Here's what you should watch for.
Is There An Odor?
Freon is a chemical that's used as a refrigerant. Despite the fact that it is colorless, it is not entirely odorless. If your freezer is leaking freon, you may notice a chemical-type odor around the unit, particularly near the rear of it. Be mindful of any changes in the odor in the air around your unit and call for an inspection and repairs if you suspect that you're smelling freon.
Is The Motor Running Excessively?
When your commercial freezer loses freon, the motor has to work much harder to try to maintain temperature. That means the motor in your freezer is going to run constantly if the system is low on freon. If you hear the motor running all the time, that's not normal. It is important that you have the unit inspected if this is happening.
Is There Any Visible Residue Behind The Unit?
When you've noticed a chemical odor around the freezer and the motor is running consistently, you may be thinking that these symptoms are caused by a freon leak. Although freon is colorless, making it difficult to see if it's leaking, there is something you can look for. Freon will leave some greasy residue on the tubing that's connected to the back side of the freezer. Look at the tubes and run your fingers over them to see if you feel a greasy film on the tubing. If you do, that's a pretty sure bet that your freezer is leaking freon and could ultimately fail.
Never try to fix freon leaks on your own. Freon needs to be handled appropriately and should only be addressed by repair professionals. Not only do you need to consider the environmental effects of freon leaks, but you also want to avoid damaging the freezer inadvertently. Routine maintenance could help reduce the risk of leaks but won't prevent them entirely. Talk with a contractor near you today for more help and a thorough inspection.
