Commercial air conditioners are usually larger, unlike their residential counterparts. That means they are costlier, not just upfront but in repairs as well. Therefore, keeping your commercial air conditioning system in a good functional condition will always go a long way into reducing your business expenses. One of the common problems you’re likely to face with your commercial air conditioning is freezing. This can happen even during hot months. Freezing reduces the efficiency of your air conditioning system, and in most cases, you’ll need to shut it down until you fix the problem to prevent high energy bills. Below are tips on what to do when your commercial air conditioner freezes up.

Inspect Your Air Filters and Clean/Replace If Necessary

Airflow problems are the most common culprits when it comes to frozen air conditioners. That’s because proper airflow is imperative for keeping the cold air warm and preventing freezing. Therefore, check the air filters for dirt and other debris and clean or replace them depending on the model of the filters. Keep in mind that sometimes an air filter that isn’t the right size can also cause airflow issues. If your air filters aren’t the problem, schedule a ductwork inspection too. Blocked ducts can also prevent proper flow of air through your air conditioning system.

Check Your Refrigerant Lines for Leaks

If you have recently replaced your air filters or ductwork inspection doesn’t reveal any blockages, consider scheduling an inspection of your refrigerant lines. That’s because you could be dealing with low refrigerant or coolant levels. The refrigerant plays a crucial role in the cooling process. Usually, the refrigerant operates at a certain level of pressure. A drop in this pressure resulting from refrigerant leaks can facilitate the condensation of moisture on the refrigerant lines. While refilling the refrigerant may seem like a viable solution here, leaky refrigerant lines should be repaired. Refilling will only cost you more since the refrigerant will continue leaking.

Inspect Your Blower Fan

The blower fan is a crucial component of your commercial air conditioning system whose function is to aid the movement of the warmer indoor air outside your home to allow the cold air to settle inside. A defective blower fan will allow the cold and denser air to settle on the coils instead, resulting in condensation and freezing. Some of the things to watch out for when inspecting your blower fan for damage include breakages and cracks.
