The 9 Best Air Conditioner Cover Defenders in all Seasons in 2020

An air conditioner cover is a heavy-duty cover you place over your air conditioner when it’s not in use. While you won’t need this cover during the summer months, it’s an excellent addition once winter hits. After all, no one uses an AC unit in winter. 

Air conditioner covers normally feature robust Oxford polyester material with vents. You pop them over the top of your AC unit, secure them with buckles and the included drawstring, then let them work their magic. They keep out rain, snow, hail, sun, and any other adverse weather conditions that could shorten the lifespan of your AC unit. 

Some are better than others, with heavy-duty material and a snug fit. Some are also priced more competitively than others. Time’s ticking, so if you want your AC unit to be safe and secure this winter, purchase an air conditioner cover. We’ve listed some fantastic options below for your perusal.

Considerations for Purchasing an Air Conditioner Cover 

You might not think that you need to do your homework before you buy a new air conditioner cover. After all, it’s a cover and not a very expensive one. However, wouldn’t you prefer to buy the right one the first time, instead of sending them back time and time again because they’re not right? The following information can make that more of a reality than ever before.

  1. Dimensions

    Before you add any standout air conditioner cover to your shopping cart, make sure you pay attention to the dimensions. Measure your AC unit (be it an indoor or outdoor one) then compare it to the measurements provided by the manufacturer. This step is important as you need to be able to get a close fit.

  2. Material

    The goal of an air conditioner cover is to protect your AC unit from the elements. Buy one with an inferior material, and it won’t stand a chance. The best material for a cover is Oxford polyester. It’s durable, long-lasting, often tear-resistant, and withstands the elements. Choose polyester at a minimum of 400 deniers.

  3. Protection

    Your new air conditioner cover must provide protection for your AC unit. Find one that will protect from wind, rain, snow, hail, bird droppings, tree leaves, mold, mildew, and more. It also helps to choose a cover with a vent that stops too much moisture building up underneath the cover.
