Importance Of Aircon Gas Top Up And Which Scenarios Call For It

When you use an aircon, you are bound to encounter some problem at some time. One of the most common problems that you might face is that your aircon does not cool the room enough and is not working as efficiently as before.

The most common reason for this problem is that there might be a leakage problem that caused the refrigerant or gas to leak. A gas top up and fixing of leakage might be the solution in such a case. In this article, we will describe the importance of topping up gas in the aircon. We will also discuss the process of how to do it and what are all the situations which may indicate that the aircon is low on gas.

Importance Of Aircon Gas Top Up

There are some important reasons why you should top up the gas in the aircon, some of which are discussed below:

  • If the aircon has decreased gas reservoirs, you will have to refill it for the aircon to function properly. Even if all the other parts of the aircon are operating and in the best condition, if the gas is not topped up, the aircon will fail to cool the room efficiently.
  • Aircon gas top-up is also necessary for the other parts of the aircon to function correctly and prevent other faults and issues. This is because a gas leakage indicates that there is some problem in the aircon unit. If it is not checked and fixed, it will burden other parts of the aircon and cause them to become faulty.
  • Aircon gas top up helps you to save money in the long run since if the leakage and other problems go undetected, it can cause the main parts of the aircon to break down. That will cost you a lot when you try to repair or replace them.
  • During the process of aircon gas top-up, any leakages that may have caused the gas to leak in the first place will be fixed. So, you can be assured that the refrigerant will not leak in the future.
  • If the gas level in an aircon is low, the aircon will have difficulty in keeping the room cool. Therefore, it will have to work much harder to try to perform better. This overworking will result in increased energy consumption and increased electricity bills. Therefore, aircon gas top-up is very important if you want your electricity bills to remain low.

Types Of Gases Used In The Aircon

When you want to top up your aircon’s gas, you have two different options to choose from:

R22 or Freon gas is usually used in the older aircon versions. Its disadvantage is that it is hazardous for the environment because of which its use is being phased out.

The other type of gas is R410A or more commonly known as Puron. It is a newer type of aircon gas which is hydro-fluorocarbon or HFC that is not harmful to the environment. This is the reason why many owners choose this gas for their aircon if it is compatible. This gas translates to better efficiency of the aircon.

Scenarios Which Indicate That Gas Top Up Is Required

There are several factors and conditions that you should look out for that may require a gas top-up of the aircon. These are discussed below:

Aircon Does Not Cool The Room Properly

One of the most prevalent signs of lower gas level in the aircon is that the room does not get cooled effectively. When you notice that the air conditioner is not able to cool the room at the same thermostat settings as before, it could be an indication that a gas top-up is needed.

The Aircon’s Compressor Does Not Stop

In the normal working of an aircon, the compressor starts for some time and, when it achieves a particular temperature, it shuts down for a few minutes before starting again to maintain the same temperature. However, if the aircon gas level is low, it will not be able to bring the room’s temperature to the desired level, and the compressor will keep on working to achieve that. Since it will be unable to do so, it will continue to run without taking breaks.

Aircon Starts Making More Noise

When your aircon starts making more noise than usual, this could mean that it has to work a lot harder than before, which is causing the extra noise. Low refrigerant in the aircon can cause it to work a lot harder than before. You can solve this problem by refilling the aircon gas.

The Aircon Starts Leaking Water Or Refrigerant

Another scenario which you might encounter during aircon usage is that it starts to leak water or liquid from any of its parts. Irrespective of how the leakage was caused, it can cause the gas to escape from the unit. This leakage means that not only will you have to fix it but also top up the gas so that the aircon can start working properly.

Ice Deposits On The Evaporator Coils

In the routine working of the aircon, air flows through the evaporator coils where heat is dissipated and consequently, the cold air blows through the indoor unit. If the refrigerant or coolant is low in quantity, the aircon is unable to function at the optimum level. This low level of coolant can make the evaporator coils freeze, and ice starts to deposit on them. When you notice this ice or if this ice melts, water will start to leak from the unit; this can indicate a low gas level of the aircon. After careful inspection, the technician will be able to determine the problem and top up the gas.

The Process Of Aircon Gas Top Up

There is a misconception that topping up aircon gas is a simple task – it is not! You need a skilled technician with all the right tools and equipment to ensure that not only is the gas filled but he fixes all the leakages as well. He will carry out a thorough check-up of the air filters and cables to see if they are faulty or not. He will also check the compressor for any damages or leakages. If he finds any leakage, he will fix it before refilling the gas.

The technician will then carry out the following steps to filling up the gas:

  • First, he will locate the suction line and the discharge line in the outdoor unit of the aircon. The suction line is used for refilling the gas in the AC.
  • Then he will unscrew the bolt of the suction line and connect the aircon’s manifold gauge to it.
  • Next, he will connect the hose of the refrigerant tank to the manifold gauge before pumping air into it.
  • The technician will then turn on the aircon and wait for its compressor to start.
  • Once the compressor starts, the technician will open the valve of the tank for 4 seconds and close it for the next 2 seconds. This ensures that the gas will be pumped slowly in the compressor. Otherwise, if the gas is released all at once, the compressor can get damaged.
  • The technician will keep on checking the pressure until the desired value is achieved. At this point, the manifold valve will be closed as well as the refrigerant tank knob.
  • The technician will remove the hose from the suction line and screw back its knob.

Once all the things have been checked and the gas topped up, the technician will test run the aircon to see if it is working efficiently.
