If you have a modest budget, then ignore brands. You can buy a good air conditioner even if the manufacturer's company is unknown to you. Try to read reviews about the air conditioner that you plan to buy. I did this. And you will buy a high-quality and good air conditioner for a modest price, which will serve you for a long time. Remember that you need regular cleaning; otherwise, the radiator will become clogged and have to make repairs. By the way, recently I had a problem with the aircon leaking water, and as it turned out, the whole situation was that the radiator was clogged and I had to change it.
