This review is praising the high quality of the sleeve, but mentions that the assembly can be difficult at times. The reviewer would prefer the screws to be self-tapping to make it easier, and feels that the directions could be more detailed. However, they mention that the installation went well and the AC fit perfectly. They also note that the inside trim that came with the sleeve covers up the new hole in the wall nicely.

The air conditioner in the upper part of the garage used for crafts was covered after bats were found getting into it.

The AC unit works as advertised and there have been no issues. The instructions were easy to follow.

After installing a through the wall AC unit in my garage, I now understand why mini split units are the better option. The actual installation wasn't too difficult, but the instructions were not helpful and the screws on the exterior of the box were not flush. This caused some issues with the wall opening. It would have been helpful to have exterior trim and waterproofing recommendations included. I had to improvise with metal flashing and window seal flex flashing. Next time, I will definitely choose a mini split unit.

This product is sturdy and simple to put together, but it does not include an outdoor screen. However, it does come with a durable panel for use in the winter.

My only problem with this item is that it includes information on various styles of AC units that fit inside the sleeve, but it doesn't include any information on Impecca units, which I find odd.

This wall sleeve is efficient and easy to install. You don't need to spend extra on an expensive brand, just make sure to check the dimensions of your wall unit. The only downside is that you'll need to purchase a sturdy metal vent cover for the end cap, though the unit does come with a solid metal cover for winter protection.

The item is functioning well and it was easy to assemble, although it does require decent hand strength. However, it is frustrating that Impecca's instructions cover how to install the AC in every type of sleeve except for this one.
