What are the Symptoms of an Air Conditioner Refrigerant Leak?

One of the biggest and most common issues that can develop with air conditioning systems is a refrigerant leak. If your system is leaking refrigerant, it can cause all sorts of performance and efficiency problems. In order to minimize the amount of damage that a refrigerant leak can cause, it’s important to know what signs to look out for. Today we’re going to talk about the common symptoms of a refrigerant leak and what you should do if you suspect your system is leaking!

 

Air conditioners don’t use up refrigerant

 

Before we talk about the signs of a refrigerant leak, it’s important to understand that under normal conditions your system should not lose any refrigerant. Your air conditioner does not use up refrigerant the way that a car uses up gas. Instead, it cycles the same refrigerant between your system’s indoor and outdoor units. When your air conditioner is operating with no problems, it will always contain the same amount of refrigerant. That’s why you should be suspicious of any contractor who keeps refilling your system with refrigerant without patching up any leaks.

 

Symptoms of an air conditioner refrigerant leak

 

    • Your home takes a long time to cool. Refrigerant is what absorbs heat from inside of your home and carries it outside. If your system doesn’t have enough refrigerant, it will take much longer for your home to cool down because there is less refrigerant available to remove heat.

 

    • Warm air is coming out of your air registers. When your system is low on refrigerant, the air that comes out of your registers will not be as cold as it should be. If the supply air from your system feels warm, a refrigerant leak could be to blame.

 

    • You hear a hissing sound. Refrigerant leaks are caused by punctures or holes in the refrigerant lines. As refrigerant leaks out of those holes, it often creates a hissing sound. This can be heard either inside your home or outside near the condenser unit, depending on the location of the leak.

 

    • Your evaporator coils are frozen over. Another tell-tale sign of a refrigerant leak is frozen evaporator coils. When there is an inadequate amount of refrigerant inside the evaporator coils, the coils will not be able to absorb as much heat as they normally would. This can cause the condensation that builds up on the coils to freeze over and can lead to a system breakdown.
