Aircon gas leaks signs

Signs and Causes of Aircon Gas Leaks

Summer is on the go and therefore, the use of air conditioners (AC) is being increased dramatically. Obviously, everyone needs to sleep peacefully in a cool environment in which air conditioning systems play an essential role these days. 

We all are aware that these devices are a true blessing however, they also require constant care and maintenance to avoid any technical issues. For instance; gas leaks. It is pretty common these days due to the frequent use of air conditioning systems, that gas leakage occurs once every two to three months. 

Therefore it is very important to make sure that you’re using the correct amount of gas in your air conditioner unit. It’s important not to overfill the tank as this will cause excess gas to escape through leaks.

Air conditioning systems that use refrigerant gases have a few different kinds of leaks that can occur. 

  1. The most common is a leak in the compressor, which is usually caused by a cracked or damaged seal. These leaks often happen because of wear and tear on the system, but they can also be caused by improper installation or faulty equipment.
  2. Another type of air conditioning gas leak is between the compressor and receiver-dryer. This type of leak occurs when there is not enough oil in the system, which causes the compressor to overheat. Increasing the amount of oil in the system will solve this kind of issue.
  3. The third type of AC gas leak happens when there is a crack in the evaporator coil itself. This kind of leak could occur because of corrosion or damage due to age or improper installation.

Leaks of this nature are costly as well as harmful to your health. Particularly if you need to buy replacement parts or employ a professional to fix them!
