A little larger than I needed, used their suggested measurement guide. Would recommend measuring interior and exterior and then choose. Nice quality fabric and cinching straps. The only design change I would suggest is not using elastic at cinch points to make it easier to get a tight fit. Overall good quality product and plan on purchasing for another unit. Also, aesthetically nice looking.

We have an air conditioner that is not used as the house went to a heat pump several years ago. It's actually in the wall instead of a window. It was a bit of an eyesore on our patio area with the typical grey cover. We measured and went with a slightly larger size for the cover and it worked. Perfect color. Love the material, it was so much better than we had hoped for. This is what an outdoor cover should be made out of!

This AC cover has performed better than any I've used in the previous 20+ years. I thought I had ordered the cover with the fleece backing and was rather disappointed to find this was just a rather thin waterproof fabric. I'd had a nice one with a thick fleece backing that covered 3 sides. It worked very well for many years. I threw it away because there were spiders on it (yes, I did LOL). I could never find that kind again so I've been using the silver or fabric ones with flimsy interlocking straps. All of them flew away with the first good storm until I started putting a piece of marble block on top. That still wasn't enough because as the harsh winters progressed, the slippery cloth worked its way off and the straps were nowhere to be found. This cover is fully waterproof and has faced hurricane winds without budging. I have an inside quilted cover but I didn't need it because no air gets past this Jeacent cover. The pair of straps fit nice and tight without sliding. It is looks dry and like brand new every time I inspect it. I have an extra large window unit and this fits perfectly. It looks like a beautiful box with no wrinkles. I highly recommend this cover. It looks like it'll last a lifetime.

It's work great with my window air conditioner

I have an A/C unit which case is imbedded in the wall. The exterior of the case is naturally, outside, exposed to the elements. Winters here can be quite cold and there was a definite noticeable cold air draft that would seep into my living room and at times, it could be felt at floor level (feet) while sitting on a couch, etc. I purchased the Jeacent Window Air Conditioner Cover. It was delivered quickly. I Sized it up and went outside to fit and strap down. After an easy install, the room temp went UP by 2 degrees within minutes.No more draft. My only regret is I did not commit to purchasing this before now..."¦"¦ small price - LARGE BENEFIT Money very well spent. Many thanks !
