Modern air-conditioning systems function on the basic principle of transferring the heat from one place to another, and a chemical compound known as the refrigerant makes it possible for air conditioners to perform this process. So basically, this is impossible for a cooling system to provide the desired indoor temperature without a sufficient refrigerant charge. On this note, an insufficient refrigerant level in your device might force you to hire AC repair Boca Raton services. So, whenever you get to know that your device doesn’t have the required refrigerant, immediately call the experts of AC repair Boca Raton for refilling the coolant.

We’re here explaining the process of refilling the refrigerant in an air conditioner without damaging any of its crucial parts. But before that, make sure you have the required equipment and expertise to refill the coolant in your AC. You need rubber gloves, protective eyeglasses, a vacuum pump with 1-4 horsepower, a refrigerant canister, and an AC manifold gauge set. You can perform the task of refilling the refrigerant in an air-conditioning system only if you have all these tools/equipment.

Let’s now understand the whole process in 5 simple steps:

• At first, locate the suction line and discharge line, which you can find in the outdoor unit of a split AC, and in window AC, both these lines are located on the backside. Suction line is used for refrigerant refilling, and it is usually colder than discharge line.
• The next step is to unscrew the bolts on the suction line, which you should do cautiously.
• Now, connect the blue hose of the manifold gauge to suction line port and the yellow hose to vacuum pump. This will remove all the air from the system because the presence of moisture inside the compressor can be seriously harmful to the entire cooling system.
• Thereafter, connect the yellow hose to refrigerant tank and start loosening the yellow hose at manifold end slightly. Then, open the cylinder knob for a second, just to remove air from the pipes.
• Then, open the low-side knob just for 3-4 seconds and then close it. After this, turn on your AC and wait for a few minutes. Now, open the valve for 4 seconds and close for 2 seconds, and do this continuously until the pressure on the gauge settles in between 60-70 PSI.
