I bought new aircond unit in box from shop.. actually top brand for aircond. Yesterday my installer ask me why the aircond no gas inside.. i dont know also.. so the installer call the aircond shop and they confirm the aircond ahould have gas inside.. so the installer fill gas inside the aircond and charge me a lot for gas.. and he also ask to watch for few days if the aircond not cool it means probably there is leak.. buy branded also face this kind of problem if i know will just buy cheap knockoff brand

Today i feel like the aircond took some time around 5 minute to give cold air from the outlet.. after that only felt cold a little
