Are you worried that your air conditioner may be leaking? We at J.R. Perkins Heating & Cooling would like to educate our readers on how to detect a leaky AC unit. Keep reading to find out why this happens, how to detect it, and how to solve for it.

When AC fans draw warm air from a room, the air travels through the ducts and flows over the refrigerant which is in liquid form. The refrigerant absorbs the heat from the air and cools it. The cold air now travels through the ducts back into the room. After absorbing the heat, the refrigerant vaporizes and moves to the compressor where it is compressed to increase its temperature and pressure. From there, the pressurized vapor goes through the condenser unit where the evaporator coils absorb the heat. The refrigerant cools and changes back to liquid, and the cycle starts all over again.

 

The refrigerant is an indispensable element in the AC unit, and without it, the system would malfunction. That’s why you need to look out for the following signs of leakage:


Your Home Takes Long to Cool

Does your home take a longer time than usual to cool? This could be as a result of a refrigerant leak. When there is a leakage, there will be little refrigerant to cool the air, and this means that the fluid will take a much longer time to absorb all the heat from the air inside your home. If you have lost too much of the liquid, the air won’t be as cool as you want it. So if you notice that your AC is on and the air is still warm, the chances are that the refrigerant is leaking.


Unusual Hissing Sounds

Refrigerant leaks usually result from small holes on the refrigerant lines. As the air passes through the punctured lines, it produces a hissing sound. Since the refrigerant lines run through the compressor and condenser units, the sound can be heard either from the inside of your home or the outside near the outdoor unit. It can be hard for you to locate the leak, so contact us for an extensive inspection of the entire system.


Frozen Evaporator Coils

As aforementioned, the evaporator coils have a role of absorbing heat from the vaporized refrigerant so that it can change back to a liquid. If there is a leak, there will be little refrigerant flowing to the condenser in vapor form. As a result, there won’t be much heat for the evaporator coils to absorb, and this will leave them cold or frozen. Additionally, it may also cause condensation to form on the coils, and this can cause the entire unit to malfunction.
