## Description

18" x 27" x 16", Silver, Window Air Conditioner Cover, Durable Polyethylene Blocks Out Water, Ice, Dust & Leaves.

Review: Great air co conditioner cover! - I bought it a little big, but with the adjustable strapes I was able to wrap it snug onto my air conditioner. It looks just like the picture, waterproof. And a good quality material. Now it will stay warmer in my room for winter.
Review: It works and easy to install - Giving it a 5 stars but material on the light weight side. My window unit is up near the top of the wall had to use a ladder to install. Very easy to install but being a universal fit it was a little larger than I needed. That's where duck tape and string comes in handy and done. Even on the ladder took maybe 10 mins to install. Like that it did not have a bottom panel making it easier to install. For the price if I get one winter out of it worth it, don't feel wind coming into the garage anymore.

## Questions & Answers

**Q: can it be used while air unit is running ?**
A: No a/c units should be run with a cover on. Besides not working properly a unit could be damaged

**Q: Is one piece for the inside and one piece for the outside? Is that what 2-piece means?**
A: The best I can figure is the second "piece" is a roll of tape. Quite a disappointment considering we have 2 units to cover; curses on false advertisement.

**Q: Window air conditioner cover small cover 5,000=10,000 btu outside wall a/c - i have 8000 btu size 28.0x26.5x17.0?**
A: It should fit O K. I have a 8000 unit an the cover is a little large you just tuck in at the comers.

**Q: Item is 10.98 at home depot, why its being sold 2.00 more?**
A: maybe because of shipping?

### ⭐⭐⭐⭐ Great
*by D***S on November 6, 2025*

Exactly what you need for covering unused ac window units during the cold months to keep the draft out. Ok quality, but a bit too big. Either way, there are no longer any drafts.
