That this problem is not so difficult to solve if you still have not solved it. You can go directly to the company from which you plan to buy an air conditioner. They should advise you on the selection of air conditioning in a particular room. I bought an air conditioner on
airconservicingsingapore.com they advised me on all the issues that arose when buying an air conditioner. Even if something goes wrong over time, they come and fix the problem, despite the holidays or busy schedule. I would recommend you to think about this option, it is very simple and convenient.
