Portable Air conditioner Window Kit, Adjustable Vertical/Horizontal Sliding Window Kit Plate for AC Unit, AC Window Vent Kit, AC Window Seal Suitable for 5.9” AC Exhaust Hose (AC Window Kit-5.9)

For real. This is the solution.

We have an extra portable air conditioner that we move from the garage to the extra bedroom that get hot. This kit is wonderful and well worth the money spent.

It was designed to fit up to 62 inches I believe. It did that, but left side gaps between the parts that slid together. They include weather stripping which is good, but this being a seasonal installation, I did not want to put foam strips in the window frame. A wider frame and weather stripping on it would be much better. I wanted to use the hose and connectors parts that came with the AC unit rather than taking the hose apart to use the parts from the kit. I just designed a 3d printed oval ring that let me use the kits oval and the B&D hose adapter. That made it work perfectly.

I highly recommend this

The panels were a pain to begin with and did not sit in the frame well. I rigged up some insulation to offset this annoyance only to find out that the hose attachment collides with our windowsill. Avoid this product if you have vertical sliding windows. Hoping I’ll be able to get a refund.

Way better than original kit. Easily adjusts between different size windows! 5 min install, if that. I will definitely get another

I was given a (used) portable AC unit just before the recent heatwave in S. Cal. The original plate that goes in the window did not fit properly, so I found this kit on Amazon. Voila! It was easy to install and works perfectly!
