Air conditioners are very popular during the summer. They keep people cool and comfortable. The most common reason for an air conditioner not working is a lack of coolant, not a temperature problem. Air flows over the evaporator coils and is cooled as the coolant circulates through it. As a result, the AC fails to function if this coolant is insufficient. Often, the cooling system stops working as a result of leaking coolant.

The refrigerant level in the evaporator coils can be accurately determined by a professional AC repair service. A modern device can be used to check for leaks and supercooling at the same time, as well as temperatures or pressure levels.

Using a pressure gauge, the PRO determines the AC unit's coolant level accurately. A top-up or refill will be recommended if the gas level, also known as a refrigerant is lower than the normal range.

It is first necessary to shut down the AC unit before starting the coolant recharge. As a result, the gauge hoses are attached to the air conditioning unit's pressure port.

 A stable state of operation can be achieved by running the AC for several minutes after it has been turned on. After this, the valves attached to the refrigerant container are connected to the AC unit with the container upright.

Important guidelines for top up gas

·      When gas refilling is starting, check that the filters and evaporator, and condenser coils are clean. An AC with dirty filters or dirty coils will not be able to cool properly, even after coolant refilling.


·      A properly functioning evaporator and the condenser fan are crucial to the efficient operation of the air conditioner. If either of them fails to operate, the air conditioner will not cool effectively.


·      You should inspect the AC unit thoroughly and look for leaks around joints and connections because leaks usually occur around the coils. 


·      You should check the air conditioner for any problems, such as obstructions.

Types of top up gas

In today's air conditioners, the following refrigerants are commonly used: -

R410A: - All air conditioners are now equipped with Puron. There is no ozone layer disruption due to no disruption of the ozone layer caused by hydrofluorocarbons.

R22: - Hydrochlorofluorocarbons (HCFC) contribute to ozone layer depletion and are commonly known as Freon. As a result of their harmful effects on the environment, residential air conditioners no longer use R22.
