Buying Guide

Here are some key factors you should consider before buying an air conditioner cover. 

Reliability

The most important feature of a window AC cover is its reliability. You need to go for a cover that comes with bungee cords to secure the cover in place on the unit. It will make sure the cover doesn’t get blown away by the wind. 

Moisture-wicking

Your cover will protect your unit from exposure to different elements, including moisture; it needs to have a waterproof design to handle it well. 

Not touching the ground

Make sure to go with a cover that is not touching the ground, or some critters will nest in your AC’s outer and decrease the overall life of your unit. 

Value 

Choose an outdoor window air conditioner cover that comes with some additional after-sale service as well. It needs to come with a warranty that solidifies its overall durability. 

Appearance

You also need to consider its appearance because you don’t want to end up with a glorified tarp. It would be better to go for a cover that adds to the overall quality of your house. 

What air conditioner cover size should I go for? 

Your cover needs to be at least a few inches shorter than the size of the AC to fit nicely and tightly. This way, no moisture will build up inside the cover. 

Are mesh covers good for an AC?

Mesh window AC covers are one of the best types of air conditioner covers. They ensure high airflow and good protection against leaves, debris, and so much more. 

Should I cover my AC in hot weather? 

Most AC routers can withstand typical weather conditions. It can partially handle sun and rain but not the blistering sun or a heavy downpour. So, you should cover your unit but don’t cover it entirely.
