Frost King window ac cover
I have been using the same cover that was here when I moved here because it was durable, which has been, 6 years! It was still really strong and kept out the cold. To put it on I used a lot of duct tape %26 was also a project taking it off! This was really really easy to install, thick and will keep the cold out! Plus protect the air conditioner from the weather. Extra note; last year I put it on in October, which meant I froze my hands and it took 3 times to get it on the ac unit! Very very happy with the ease of application. I want to thank you!
