hey bro, can i know what is G22 stands for ?
G22 or G23 refers to the thickness of the gas piping so G22 is thicker than G23 as the number goes smaller.

Below is the blog page you can read up a bit, I also read up from there which many air-con companies got promotion on free upgrade of gas piping from G23 to G22 like the Daikin ProShop.
