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

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

When we say extreme weather, we are not just talking about snowy winters, but something more. If you are residing in those cold northern states of the US or Canada, then you may consider using a cover. If your region is prone to hail storm, blizzards, or any other unpredictable winter calamity, then you would prefer using an air conditioner cover.

But there’s also risks when you choose to cover your outdoor unit:

  • Rodent and pest infestation
  • Growth of Mold and Mildew
  • Seepage of moisture causing the air conditioner to rust
  • Dirt settled over time could be sucked in while in use.

We don’t recommend using a cover all winter long - that brings risk, and your unit doesn’t need the protection. Save it and install it when those rough patches are coming.

What to Look For When Buying

Air conditioner covers help in preserving your air conditioner for the next hot season,so you want to purchase a cover that ensures durability and safety. Here are some factors that we have listed down for you, that would help in making a smart purchase decision.


Since it is recommended to use a cover to save your air conditioner from extreme cold winter disasters, ensure that it is waterproof. It should not allow water to settle and seep into the A/C. This helps in keeping away moisture, mold and mildew.

Easy to Install

Look for installation instructions while purchasing a cover. Review them before you make a purchase decision.

What Size of AC Cover Do I Need?

Before you pick a cover for your air conditioner, you really need to look at the size of your unit. The size of the cover, very obviously, depends upon the size of the air conditioner. It is better to measure the dimensions of your air conditioner yourself, rather than to rely on the mentioned dimensions since they aren’t always the most accurate.

Another thing that you need to keep in mind is that you should always pick a cover that is the right size for the dimensions of your AC. If there is none that corresponds with the given dimensions, choose a bigger unit that’s closest to the size of your AC.

Aerated and Porous

While you need to look for an intact cover, it should also be well-aerated and have enough porous material to allow air to flow in and out. This helps in keeping away any stench that can occur.


The warranty of the cover speaks for this. Yes, your cover needs to come with a warranty period stating that it is durable for a minimal period. A good warranty would last for a minimum of 2 years.


This is most important for window units. Based on the region you live in, you would sometimes need insulated cover to keep away the cold. Check if covers come with this feature.

The vinyl is resistant to both water and puncturing, something that could happen when putting it on or taking it off.

The cover is resistant to the effects of sunlight, including fading and brittleness after continued use.

Bottom Line

The combination of breathability and proven resistance is a great selling point for this product. There have been complaints that the cover is a bit too light for places with harsh winters, but it’s otherwise a great AC shielding option.

Amazon Basics Outdoor Square Air Conditioner Patio Cover


  • Reasonably-Priced
  • Easy to Install and Clean
  • Strong and Durable Design
  • Can Be Used on Furniture as Well
  • Comes with Amazon’s Guarantee of Quality


  • Does Not Adjust well to Fit Smaller Units

Part of the Amazon home staple, this is designed to fit a wide range of air conditioners. It’s made from 100% polyester, which protects from dirt and dilutes the effects of the sun as well. It’s waterproof to keep out rainwater and snow, is built with durability in mind, and comes with interlocking seams that are harder to weaken and rip over time.

It’s easy to use and slips on the AC unit easily. There are loop handles to help in the removal, and in making any adjustments to the fit as well. It has click-close straps that fit securely around the unit and make it harder for strong winds to rip it off. It’s easy to clean, requiring a simple wipe down with a damp cloth to take care of most of the dirt.

There have been two main complaints about the product, however, with some customers claiming it doesn’t fit smaller air conditioners as well as it should. It’s also been known to pool rainwater at the center of the cover, meaning you have put something underneath to encourage runoff. A soccer ball works just fine. Place the ball on top of the air conditioning unit, but under the cover for best results. The white color has also been termed garish by some people.

Bottom Line

Being part of Amazon’s in-house product line, there’s a certain quality guarantee. The straps work great for some time, but the plastic heads get weaker and break over time.

Pros and Cons of Getting an AC Cover

Every product in the market comes with a set of pros and cons, and so do AC covers. Whether the pros of the item make it worth buying regardless of the cons is a decision that you make for yourself. In order to help you decide, here are some pros and cons of investing in an AC cover


Let’s first take a look at the pros 


Over time, a great amount of dust can find a place in your air conditioner. This gathered dust proves to be damaging for your unit. With a cover for your air conditioner, you will ensure that your unit is protected from all such particles that may impair the functionality of your air conditioner.

Better Energy Consumption

As mentioned above, without any cover, a lot of dust may layer up in your air conditioner. This dust can prevent your air conditioner from performing the best. It requires a lot more energy to provide the same functionality, which may add to your electricity bill. So an AC cover may also contribute to better energy consumption.

On the other hand, there are some limitations to deal with, which include:

Extra Cost

Air conditioners themselves are expensive products. Getting a cover for them is an extra expense. While some users may find the unit worth the expense, others feel that the quality of build of air conditioners don’t really require the extra expense of an AC cover.


The needs for external air conditioning units vary. Also, only use covers for external units when necessary. Be sure to invest in a cover that serves a purpose beyond looking good, too. Covers can help prolong the life of your unit and keep your utility bills down when used appropriately.
