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)

Like many others, this extension kit is far better than what came with the DeLonghi air conditioner unit. As a determined 65 yo, I was able to install myself. It would be easier with 2 people but doable alone. Instructions could be a lot better, I watched a You Tube video to make sense of it before starting. No tools needed other than scissors to cut sealing material. Plus, plenty of sealing material. It is very sturdy, appears to be durable but this is just my first season. I would highly recommend.

This is better than the original part. It was easy to assemble and works better than the original part.

I have an old Delonghi portable AC unit and for the life of me couldnt find my window kit. I purchased this right at the beginning of summer and with it being adjustable it fit my window perfectly. Comes with everything you need. The adjustment screws held very well and lasted all summer. This time I made sure to put it away safely so I can use it again next summer.

The difficulty I encountered installing this was: a) wouldve been easier with 2nd set of hands b) basic instructions wouldve helped c) I was adapting it to a different feed connector & it took me far to long to realize I was approaching it wrong. Some or none of these problems could happen to you. All that being said, in the end it fit perfectly on my oversized vertical windows & Im very happy to have found it!

Great item fit perfectly

Works as intended, arrived very quickly.

Works better than the original one

its ok. just dont move the hose or look at it too much and it wont falll off. its mainly how the hose attachemt hooks to the window spacer. mine is always falling apart.

Everything was there exactly as described

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.
