4 Signs You Have a Refrigerant Leak in Your Commercial Air Conditioning System

Commercial air conditioning systems tend to be larger than their residential counterparts. That means a fault somewhere in your commercial air conditioning system can turn out to be very expensive to repair if it’s not detected early enough. Refrigerant leaks are some of the problems you may experience with your commercial air conditioning system. The refrigerant plays a significant role when it comes to the effective functioning of your air conditioning system. If you are running low on refrigerant due to a leak, your system will be forced to work harder to cool your space, which can result in significant damage to parts such as the compressor and high electricity bills. Being able to identify the signs of a refrigerant leak early enough can save you from significantly costly repairs. Here are some of the signs to watch out for.

Reduced Cooling Power

Loss of cooling power is the first obvious sign that you could be dealing with a refrigerant leak. That’s because of the refrigerant’s vital role in the cooling process, which involves absorbing the heat from your commercial space and releasing it outside. A leak in the refrigerant lines will result in your commercial space taking longer than usual to cool.


Frost build-up on your refrigerant lines and other parts such as the evaporator coils and the fan motors are also another indication of a refrigerant leak. When you have a refrigerant leak, the refrigerant that remains in the refrigerant lines or coils will lose heat absorption and remain cold such that moisture along the surface of the coils will freeze. Therefore, watch out for iced-up refrigerant lines.

Warm Air from The Registers

If you notice that the air from your vents is slightly warmer than usual, it could be due to a refrigerant leak somewhere. That’s because low levels of refrigerant will affect the cooling power of your air conditioning system, making it struggle to cool your space.

Hissing/Bubbling Sounds

Be keen to identify any strange sounds from your air conditioning system as it runs. Bubbling or hissing sounds are usually associated with refrigerant leaks. That’s because, in most cases, the leaks will be caused by small cracks or holes in the refrigerant lines, which is why you will hear hissing sounds similar to those produced when air is escaping from a punctured tube.

The best solution for refrigerant leaks is finding their source and having it repaired. Topping up the refrigerant may look like a cheaper alternative at first but will turn out to be costly later on because the refrigerant will still leak, meaning you will have to top up again.  If you have a refrigerant leak in your air conditioning system, contact Conditioned Air today.
