If you want to keep your home cool and comfortable all year round, you need to make sure your air conditioner is running at peak efficiency. Making sure the air conditioner has the proper quantity of refrigerant gas is an important part of routine maintenance. The effectiveness of your air conditioner may decline as the gas supply dwindles over time. This is why having AC gas filling and maintenance from https://www.socool.sg/ is important.

When AC gas is low, you'll need to have your air conditioner's gas tank replenished. In this quick reference, we'll show you the ropes for refueling your air conditioner's gas tank. If you follow these guidelines, your air conditioner will be ready to keep you cool during the hottest days of summer.

Step1. Safety First 

Putting safety first is a must before beginning any work on your air conditioner. Make sure the unit's primary electrical panel is unplugged from the wall. As a result, you won't have to worry about getting shocked when working on the air conditioner. If there is a risk of leaks or sprays of refrigerant, you should also wear safety gloves and eyewear. 

Step2. Identify the Refrigerant   

Refrigerants like R-22 and R-410A are just two examples of the many options available for use in HVAC systems. Your air conditioner's refrigerant type must be determined before you may add petrol to it. You can find this data in the user instructions or on the product's label. Note that gas filling processes and tools will vary depending on the refrigerant being used.

Step3. Check your leaks 

Checking for leaks in the air conditioner is a must before adding gas. A rapid loss of refrigerant due to a leak can render a filling operation useless. Oil stains or hissing noises are indicators that there is a problem with the refrigerant lines, connections, or joints. Before starting with petrol filling if you detect a leak, it is advisable to contact an expert technician who can find and remedy the leak.

Step4. Gather the Required Tools and Equipment 

There are a few essentials you'll need on hand in order to refuel your air conditioner. You'll need an adjustable wrench, a refrigerant cylinder with the right kind of gas, a charge hose with a valve, and a gauge set for the manifold. Check that your air conditioner has plenty of the right kind of gas.

Step 5. Connect the manifold monitoring set 

Connect the AC unit's service ports with the manifold gauge set. It is common practise to designate the service ports as either "High Pressure" or "Low Pressure." Pair the high-pressure red hose with the blue low-pressure hose. For the time being, the yellow hose has not been connected.

Step6. Open Valves and Start the AC Unit 

Turning the manifold gauge set's valves in an anticlockwise direction will open them. This will cause the gauges to display the correct pressure levels. Turn on the air conditioner and allow it to operate to a few minutes once the valves have been opened. This must be done in order to maintain system stability and obtain reliable pressure readings.

Step7. Read Pressure Levels

Keep an eye on the pressure readings displayed by the manifold gauges. Pressure in the liquid phase is read off by the high-pressure gauge, while vapor-phase pressure is read off by the low-pressure gauge. Check the results against the pressure range specified by the air conditioner's manufacturer. The user manual or the manufacturer's website should contain this data.

Step8. Attach the Charging Hose

Connect the charging hose with the lower-pressure service point on the manifold monitoring set and the refrigerant cylinder once it is established that pressure levels are below and gas filling is necessary. Before plugging in, make sure the charging hose's valve is closed.

Step 9. Open the Charging Hose Valve

Gradually open the charging hose's valve. By doing so, the refrigerant gas might enter the air conditioner. Fill the petrol tanks to the proper levels while keeping an eye on the pressure gauges. Overfilling can damage the air conditioner, so be careful.

Step 10. Close Valves and Disconnected

When the desired pressure has been obtained, the charging hose should be disconnected through the a low-pressure service port and the valve should be closed. Turn off the manifold monitor set and seal its valves. Follow all safety precautions when handling the refrigerant cylinder, and always keep it in a cool, dry place.

Step 11. Test and Monitor

It is important to check for leaks and other problems after refilling the gas in your air conditioner. Start up the air conditioner and see if it is effectively cooling the room. Any strange sounds or odors could be an indication of an issue with the gas filling procedure or other parts of the system, so pay close attention. It's best to get in touch with an expert to get additional inspection and assistance if you find any problems.
