AC Gas Filling in Chennai



The lack of gas refrigerant in the AC (Freon) is the common reason behind AC not cooling properly. The coolant flows through the evaporator coil and cools the air moving over it, thereby sending the cool air into the room. And when the level of the coolant gets down, the AC is not able to cool properly. In many instances, the coolant leaks from the AC unit and the AC stops cooling. An AC repair professional should be called to check whether the level of coolant is sufficient in the cooling coils.

AC gas refill service

The AC repair technician accurately check the refrigerant level in the AC unit with the help of a pressure gauge. If the level of coolant is found below normal, the professional suggests you a refill according to the requirement.

To begin the coolant refill, AC unit needs to be shut down. After that, gauge hoses are connected to the pressure port of the AC unit. Then the AC unit is turned on and allowed to run for 10 minutes so that it can attain a stable state of operation. After this, the valves of the coolant container (with container in the vertical position) is linked to the AC unit. The AC unit can draw coolant now.

Reasons for AC gas Leakage

Manufacturing defect

It is not necessary that manufacturing process is always 100% free of errors. There are many joints and welds in the AC unit that could cause a leak if they are not made with high accuracy. If there is manufacturing defect in the unit, leakage will happen during the early stages of use and therefore can be fixed up under warranty period

Incorrect installation

The most important part of AC installation is making flare nut connections and bending the copper pipes, which are the most common sites of coolant leak. In order to avoid the leakage, flare nuts must be sealed with Teflon tape while the copper pipes should be bent through a tube bender.

Regular wear and tear

Air Conditioners are pressurized units and with time bolts and nuts can become weak.

Types of AC gases

All air conditioners don't work with a common refrigerant. Here are some of the common refrigerants used in air conditioners:

R410A gas - also known as Puron (brand name). This gas is used in all the latest air conditioners now. It is a hydro-fluorocarbon (HFC) and does not deplete the ozone layer.

R22 gas - also known as Freon (brand name). It is a hydro-chlorofluorocarbon (HCFC), therefore has a potential of ozone layer depletion. R22 is used in 50-60% air conditioners in India as of now.

R290 gas - It is a hydrocarbon refrigerant. It is the most eco-friendly coolant available in India for the air conditioners. R290 has no impact on the ozone layer. R290 is energy efficient. But it is highly flammable.

Important guidelines for AC gas filling

Before the refrigerant filling process starts, it is always recommended to see if the air filters are clean and evaporator coil are free from dirt. If they are not dirt free, AC will not be able to cool properly even after the coolant recharge.

Check for any obstructions inside the AC unit like loose or broken parts.

Ensure that evaporator and condenser fan function properly. If any of them is not working fine, AC won’t be able to cool effectively.

Inspect the AC unit and see if there is any leakage in the coils. Leaks are usually found around joints and connections.
