SereneLife Portable Air Conditioner - Compact Home A/C Cooling Unit W/ Built-in Dehumidifier, White

Initial review: we got these units as supplements to our central air in Phoenix. It does a great job in cooling down our sleeping rooms where the central air just isn't able to cool those areas very well. I made some modification when setting up the window hot air exhaust hose. - you will probably need an additional window kit. Our vertical window was too large and our smaller winders were too small for the kit that came with the units. Too bad because they seemed like good quality items. - to add stability for the exhaust plate block In the window, I cut some cardboard, rolled it up into a round long piece, wrapped it in duct tape and wedged it between the window and the plate. This keeps the exhaust plate my more sturdy in the window. - on my vertical window, to keep it from sliding open at all (unlikely to happen but still) I had some suction cups that screw onto the window and increase the suction grip as you screw. I placed three of these along the window and now they won't open at all. - to create some more insulation at the exhaust plate, I cut a piece of cardboard to the plate and then bought some foam insulation and glued it to the cardboard. Now just place that in the window behind the exhaust plate to prevent more hot air from coming in.
