Review: Great product!! - Excellent item! Works great on the air conditioner!! Protective, keeps outside blowing dirt, dust and cold weather from entering the house! Perfect fit as well.
Review: worked great through the NE US winter - As I'm getting older and it's gotten harder for me to handle window air conditioners on my own, last year I decided to try leaving them in off-season for the first time. I got these covers for the downstairs ones, and they were super easy to use and held up very well. Took just a few minutes to install them using a step ladder, and the straps allowed me to get a nice, snug fit. I'm in the northeast U.S. so they saw plenty of nasty winter weather, but at the end of the season, they still looked new. Happy I got them, leaving the window ACs in again this year and installing these again, and hoping they hold up as nicely for several years. Not lugging the ACs out and back in has been a gamechanger for me, and I'm appreciative of the role these covers played.

### ⭐⭐⭐⭐⭐ Great AC covers.
*by J***. on November 13, 2025*

Great air conditioner cover. I purchased 4 covers. Well made, insulated, waterproof, blocks some of the outdoor sound and prevents cold and winds from entering. Excellent straps in holding cover in place. I'm glad I purchased them.
