Back when I had a window air conditioning system back in the day, I recall it being a real hassle right at the end of summer when fall was coming around. You would get all kinds of tree debris and leaves blowing onto the part of the window air conditioning unit that sat outside the window. Cleaning it off was really tough to do. Especially if it was on a 2nd floor room. In these cases I had to always make the bedroom filthy and bring all that tree debris in when I was taking out the window air conditioning unit to put it away for the winter. I would have to vacuum up all the junk off my bedroom floor and then sanitize it as well. It was more or less having to do a deep clean of the bedroom after all of this. I am so glad these days are long gone and today everyone has central heating and air conditioning systems. I do not miss the days of window air conditioners one bit! Having central air conditioning there is no uninstalling it every single year. It is there all the time and also works as your heater. Though central heating and air conditioning systems are much more pricey in energy to run than window air conditioning units or even gas furnaces, I still prefer central heating and cooling over the way things used to be. Especially when it comes to window air conditioning systems. I am sincerely not a fan of window air conditioners for the exact reason I explained above with the tree debris!
