When to refill gas for air conditioner?
Air conditioners that need to be charged with gas will show signs of concern as follows:
Cold air conditioner: When the air conditioner is short of gas, the first sign that can be recognized is that the air conditioner is not cold, it takes a lot of time to cool the room.
Flicker off error light: For some models of air conditioners that have a notification function when the machine has a problem, the flashing of the error light is also a sign that the air conditioner is short of gas.
Auto on/off: The air conditioner works for about 15 minutes and automatically turns on and off, which is also a sign that the air conditioner is short of gas. When the air conditioner automatically turns on – off, first of all, you need to check the modes on the remote to see if they have adjusted correctly. If the remote has adjusted correctly, the cause may be damage to internal components.
Leaking water on the indoor unit: When the air conditioner is short of gas, there is a high possibility that the machine is showing signs of leaking, causing the indoor unit to cling to a lot of snow and even freeze inside the indoor unit. Therefore, a watery indoor unit is also one of the signs that the air conditioner is short of gas.
Snow on copper pipes: When the copper pipe is covered with snow or water leaks, then surely your air conditioner is having a leak problem and gas shortage.
There are many reasons leading to a lack of gas in an air conditioner, some of which are common such as:
- Scattering head: Bloating is the most common cause of gas shortage in the air conditioner. There are many causes for the top of the canopy to leak such as: weather, time of use, etc. Therefore, before recharging the gas, it is necessary to treat the top of the canopy or change another canopy.
- Hot or cold condenser: If, after checking and treating the canopy, but still can’t overcome the lack of gas on the air conditioner, now we need to plan to try to leak the outdoor and indoor units. The testing of the outdoor and indoor units is quite complicated, so it is best to contact a skilled technician for the best support.
- Brass pipes: When the copper pipe is deflated, you will find a layer of snow on the copper pipe. When the snow layer melts, it will lead to water leakage on copper pipes. This case often causes the walls of the house where the copper pipes are located to be moldy, even leaking water in the house.
When the air conditioner runs out of gas, you have to face the following “terrible” things:
When you run out of gas, you will not feel the cool air you want. Therefore, you often lower the temperature than usual, leading to power loss no matter how energy-saving inverter air conditioner you use.
- Damage to other components
Air conditioners with gas leaks often appear in the condition that the air conditioner freezes, leaks water and operates overloaded. If you do not have a timely remedy, the device will easily damage other components such as Kapa (capacitor), block. Over time, the air conditioner can be damaged, bringing many dangers when used.
- Affect health
When the air conditioner is leaking water, there will be many serious harms that directly affect health, work as well as finance. The hot air even though the machine is still working makes you uncomfortable, not focusing on work.
4. Types of gas commonly used when filling air conditioners
Currently, on the market, there are 3 most popular types of gas being used for air conditioners: R410, R22, R32 and Refrigerant.
This is a commonly used gas because of its low cost as well as the simple gas filling process, which does not require much technical and equipment requirements when filling gas.
Gas R22 has the ability to tolerate additional impurities, so when the gas loader only needs to measure the amount of gas to be charged and can proceed with additional charging without having to discharge all the remaining gas in the air conditioner. However, this gas is relatively poorly cooled as well as it is harmful to the ozone layer.
Usually has a mid-range price, the charging process is relatively complicated, requires high skill of gas loader as well as full use of specialized equipment. When filling up with R410 gas, the worker must completely replace it even though there is still old gas residue inside the picture.
Advantages of gas R410: Capable of creating deep cold as well as saving electricity.
This is a new gas that has been used since 2014 and is a common gas on most air conditioners today. This type of gas is similar to R410 gas, when it is loaded, it requires skilled technicians as well as specialized equipment.
Features of R32 gas: Has extremely strong and stable cooling ability (more than 1.6 times- R410A, more than 6.1 times R22) thereby helping your air conditioner to save significant energy.
4.2 Origin of gases
Most of the gas used today are imported from many different sources such as China, the UK, Germany, India, etc. However, the most popular is still the type of gas imported from China and India.
According to experts, the gas imported from India has better quality than from China.
Gases from the UK and Germany are of high quality and meet safety standards when used, but the cost is relatively high and usually only when there is an order to be imported.
Hopefully after reading this article, you will know and better understand the replacement time and the type of gas to choose for your air conditioner!
