AC Refrigerant Leak – What You Need To Know


Refrigerant leak in air conditioning systems is quite common, but it is not easy for an average homeowner to detect. When coolant leaks happen, it impacts the functionality of the air conditioner and reduces the comfort level of your home. The experts of aircon installation Sydney explain more about refrigerant leak right below.

What does an AC Refrigerant Do?
  • The refrigerant is a chemical compound that is distributed across different components of an air conditioning system.
  • This is first pushed to the compressor where it’s compressed into gas molecules. These molecules will collide with each other to produce heat.
  • The hot gas is then transferred to the condenser. The fans of the condenser will now remove the heat. As it cools down, the refrigerant gas will be condensed into liquid.
  • Now, the liquid refrigerant is moved through the evaporator coils where it is cooled down even further. The air that blows over the evaporator is cooled and distributed to your room.


What causes the AC Refrigerant to Leak?

Here are a few reasons that lead to refrigerant leaks:

  • Incorrect installation of an AC unit will lead to refrigerant leaks. Make sure that the aircon installation Sydney is carried out by a certified AC professional.
  • The metal components, such as copper pipes, present in the AC unit can get corroded and form holes. If this happens, the refrigerant will start to leak.
  • Regular wear and tear due to frequent usage of the system will breakdown the components, which further causes the refrigerant to leak.
  • If there is a manufacturing defect in your air conditioning unit, that could also possibly cause the refrigerant to leak once it is installed.
