I have an LG LW1804ER window air conditioner that was professionally installed in an apartment building window. It does have support brackets outside that angle from the bottom-back of the unit and rest against the brick facade of the building. I'm on the fifth floor, by the way.
I need to open the window sash to do a couple of things. I'm going to put a "Stop-Drop" foam covering on top of the external AC enclosure to dampen the sound of the upstairs neighbor's AC unit, which is directly above mine. It drips water constantly, which is like the proverbial water torture inside our apartment. As an aside, this is what I'm going to install:
My question is this: There are just a couple of small screws fastening the top inside bracket of the AC unit to the sash. I can't imagine that the window itself is supporting too much weight of the AC (in other words, the natural force of the AC to want to just fall out of the window) because of the brackets underneath the unit. But, I'm not sure.
I don't want to remove the screws and open the sash only to have this thing lurch toward the outside and somehow fall. Yeah, yeah, with the brackets, that shouldn't be possible. But the only dumb questions are those that aren't asked. Should this be safe for me to do? It will only be me working on this thing for the time the window(s) will need to be opened. I'm no weakling, but I only have two hands, and can't do the work I would need to do with only one hand, lol.
So, am I good to go on this project? Tks.
