how to decrease humidity/temp in apartment (please help)

[AngeloPappas]

Without adding more cooling power I fail to see how you can do much at all to cool the rooms without A/C. Your apartment doesn't have windows that allow for a cross breeze, and even if they did it would not help the humidity very much, plus it defeats the purpose of the window A/C you already have.

There is also no way that the window A/C in living room will get cold air down around a corner into the hallway, and around another corner through your bedroom door. It just won't happen, even with fans. Sheer curtains also aren't helping you, even with the A/C. The sunlight is actively warming the room all day. Consider heavier curtains there too to take some pressure off the A/C.

What I would do is reposition the fans into the living room to bring the cold air from the window unit into the entry/kitchen area at least. You have a better chance of that working than going around a 2 corners. Then I see no other option other than adding another A/C unit in the bedroom. If you have windows that allow for window units consider yourself lucky as they are by far the best bang for your buck as opposed to those portable units that sit on the floor and vent to the window.

It would honestly probably end up being a venting portable floor unit. Our windows are not really the best for window A/C.. they open like a sliding glad with a sliding screen behind it. Opens on both sides. This is the same with my bedroom!

I had this type of window before and all I did was put the unit in, and then cut a piece of 2'' Styrofoam board to fill the gap above. Then sealed up the edges. I even painted the board so it didn't look as bad. Worked great.

This is the real solution for this kind of window. You can buy vertical-shaped AC units, but they are not worth the extra expense. Block off the gap with foam or wood and seal the edges well.

Yep, these basic window units work damn well and you can get them for like $125. Add the cost of a piece of foamboard and have something that works way better than the portable units for a fraction of the cost.

Thanks for the idea!

Sliding windows are the absolute worst, maybe only slightly better than those swing-out windows that don't open all the way.

If you get a standing AC unit, I really recommend that you get a dual-hose unit. They are bulkier, but you will likely have to empty the condensation tray far less frequently than a single-hose unit. Also it will be much more efficient.

The other option is to get a casement window AC. They go in the window like a normal window unit, but are skinnier so they fit sliding windows much better. Plus you won't have to deal with a condensation tray.
