Signs Your Coolant May Be Running Low

Your commercial refrigeration unit requires coolant to function correctly. Just like you stay on top of everything else in your kitchen to confirm no repairs are necessary, be on the lookout for signs that your walk-in cooler may have low refrigerant levels. The following warning signs all indicate you should check coolant levels or hire an Orlando refrigeration repair professional.


At any given moment, your refrigerator should be relatively quiet, as should most other appliances. There will be the occasional humming sound, but if you hear hissing or anything else, check the coolant levels. This noise may be from the unit attempting to use coolant which isn’t there. No matter the reason, unusual noises are never a good thing from your commercial fridge.

Fluctuating Temperatures

If you notice fluctuations in the temperature of your unit, this may be due to coolant levels. Maybe you notice ice starting to form or see that the temperature gauge always displays a different temperature. In this case, there is barely sufficient coolant for the unit to remain cold. Every time you open the door, the system cannot maintain the temperature. If adding more coolant doesn’t resolve the issue, call your repair technician.

Odd Smells

Most people assume that an odd smell coming out of their commercial fridge is due to food, but it can also be from a mechanical or coolant issue. If the system doesn’t have enough coolant, it will let out an odd, sour smell. You may also notice that your food begins to spoil more quickly than normal.

Get to the Bottom of the Problem

Anytime the coolant levels are low on your commercial refrigerator, you need to get to the bottom of the problem as soon as possible. Even if you fill this fluid, it may get low again, particularly if there is a leak or another underlying issue. Not only do leaks cost you money, they reduce your system’s efficiency and the refrigerant gases that can omit from a leak significantly harm the ozone layer.
