This is a detailed answer with which I largely agree, I just want to point out that the installation of better insulated windows shifts the problem in insufficiently insulated buildings to other areas, often the moisture then settles in corners and leads to mould there - in the past it was said that the window should always be the coldest surface in the room, today there are Ventilation, insulation,… but i think this is still a good rule
Good Timing - I had to choose between Panasonic and Haier AC, now i will happily avoid Haier/Candy/Hoover/GE Appl. I hope they get a lesson
