Why Do You Need An Air Conditioner Cover?

Truth be told, there’s always a chance that you don’t need one. Depending on how the climate is in your area, your air conditioning unit can be safe outside all year round.

Things get a little more complicated and extra-care becomes essential if the winter freezes. So, one reason you might need an air conditioner cover is to protect your unit from excess moisture.

For those of you living in areas where winter is equal to heavy snowfall or rainfall, prevention is key. It is far from desirable to have snow or water infiltrating your AC circuits. Adequate air conditioner cover ensures proper airflow and keeps excessive humidity under control.

This way, the integrity and performance of your unit has been going on for more years. Small animals are another threat that lurks around the house and can cause damage to your AC. There are many potential unwanted inhabitants, from mice to other tiny creatures.

Nesting inside the outside part of your air conditioner is bad enough.

Now imagine how things get worse, because these animals can start chewing on the wires.

You would have to replace components all the time and the air conditioner covers unwanted costs. Appropriate air conditioner cover can block access for rodents and other animals in order to prevent them from making a nest.

One more aspect that can be considered in your decision to cover your AC unit. Spending a consistent amount of money on your home cooling system means you want to avoid additional costs.

An air conditioner cover may be useful to prolong its well-functioning and prevent unnecessary complications.

Of course, you need to make sure that the air conditioner cover is better than the damage. And for that, please read our tips and recommendations below.

When Should You Use an Air Conditioner Cover For Your Outdoor Unit?

As we mentioned earlier, your outdoor air conditioning unit is already designed to withstand the extreme conditions of winter, but you may want to consider using an air conditioner cover during the maintenance season.

This saves your air conditioner from extreme weather conditions. When we say extreme weather, we’re not just talking about snowy winters, but something more. If you live in the cold northern states of the United States or Canada, you may consider using an air conditioner cover.

If your region is prone to hail storms, blizzards, or any other unpredictable winter calamity, then you would prefer to use the air conditioner cover. But there are risks when you choose to cover your outdoor unit as well:

  • Rodent and infestation of pests
  • Mold and Mildew Growth
  • Seeding of the moisture that causes the air conditioner to rust
  • Dirt settled overtime may be sucked in while in use.

We don’t recommend that you use an air conditioner cover all winter long-that brings risk, and your unit doesn’t need protection. Save it and install it when the rough patches come in.

Features and Considerations of The Best AC Unit Covers for Winter


Think of the air conditioner covers as coats for your air conditioner. You wouldn’t buy a coat that isn’t made of waterproof and high quality materials.

There are a number of different materials used to make these products. Polyester is common and available in a variety of different deniers, measured by the “D” rating set out in the product description. Mesh materials are available as well.

Whichever material you choose usually has some form of laminate or PVC coating, this helps to make it more waterproof. You should be looking for durable and hard-wearing covers that can protect against the elements.

Water Resistance

Most of the problems that may arise from not having a cover may involve water. Whether this means the unit filling up with water or freezing the water and causing damage to the coil, it is worth finding a product that you can be confident will repel the water.


To prevent any water from freezing, a little insulation can often help to keep the temperature inside a little higher.


Some air conditioners come in a variety of different sizes, others have a specific size, others are adjustable. The important thing is that you match the size of your air conditioner. A cover that doesn’t fit is totally useless.


This isn’t supposed to be a difficult process! The best central air conditioner covers are easy to install. The top designs are simple, so there’s no need to read a lot of instructions. They’re either going to slip straight on, or they’re going to strap around the air conditioner. Some drawstrings are designed to pull them tight and adjust the size.


We’ve been looking at the bottom of our list because it’s not the most important thing. Looks are completely superficial. However, if your AC unit is in the backyard that you’ve spent a lot of time decorating, an air conditioner cover that looks good, or at least isn’t eye-bite, that’s a real plus.

Top 7 Best Air Conditioner Covers in 2021

Curious birds, lizards, and small mammals, such as raccoons, are particularly prone to “visit.” The ac cover is resistant to the effects of sunlight, including fading and brittle after continued use.

It’s also known to pool rainwater at the center of the cover, which means that you’ve put something underneath to encourage runoff. A soccer ball is just fine. Place the ball at the top of the air conditioner unit, but under the cover for best results.

Some people have also referred to the white color as a garnish. As part of Amazon’s in-house product line, there is a guarantee of quality. The straps have worked great for a while, but the plastic heads are getting weaker and broken over time.
