I also look for a kit that is easy to install and remove, especially if I plan to move the AC between rooms.
Window Compatibility Matters to Me
The first thing I check is whether the kit matches my window type. I make sure it works with sliding windows, vertical windows, or whichever style I have at home. I also measure the window opening before buying, because even a small mismatch can make installation frustrating. For me, compatibility is the most important starting point.

Material Quality I Trust
I look for durable materials that can handle regular use. A sturdy window kit feels more reliable and lasts longer, especially if I remove and reinstall it often. I prefer lightweight but strong plastic or similar materials that do not crack easily. In my experience, better build quality usually means fewer problems later.
Portability and Storage
Since I use a portable AC, I want a window kit that is easy to store when not in use. I like compact parts that do not take up much space in my closet or storage area. If I move the AC seasonally, I also want the kit to be easy to carry and reassemble. Convenience matters a lot to me.
What I Check for Extra Features
I sometimes look for extras like extension panels, foam sealing strips, or adapters for different exhaust hoses. These features can make the kit more versatile and help it fit better. I also like kits that are designed specifically for LG portable air conditioners, because that usually gives me more confidence in the fit.
