AC units have a tough life, but they can be protected using a good air conditioner cover. Outdoor units are constantly exposed to the elements, while window and wall units hang half in and half out. And they aren’t cheap. They can also become a target for pests, allow drafts to penetrate the home, and can even break or deteriorate at the hands of Mother Nature. With the right AC unit protection, you can extend the life of your air conditioner and ensure access to cool air for years to come.
Air conditioning covers fall into several categories, but they all protect the AC unit from damage, drafts, and pests, and they’re one of the best things you can do for your AC. Our favorite is the Joiish Air Conditioner Cover With Waterproof Top, which consists of a full-size mesh cover for an outdoor air conditioner unit as well as a waterproof top that can be removed. This guide will highlight the best air conditioner covers on the market as well as some things to know when shopping for these handy accessories.

How We Chose the Best Air Conditioner Covers
We know it’s important that folks feel comfortable with their covering for air conditioning units. No one wants to be chasing a runaway cover in a windstorm or uncovering their model in the spring only to find damage, mold, or other problems. That’s why we took the task of putting together a list of the best air conditioner covers so seriously.
First, we considered the types of air conditioner covers that shoppers would find useful, including covers for central air outdoor units and window units. Then, we outlined a variety of key features that AC covers should offer (depending on the type of cover) such as proper coverage, insulation, waterproofing, and breathability. After that, we performed extensive product research to find products that could meet our standards. We then compared products based on these key features to determine which offered enough value and which didn’t. Below are the products that made the cut.
What to Consider When Choosing an Air Conditioner Cover
Purchasing the wrong air conditioner unit cover can be the start of a frustrating experience. Avoid this by learning all of the different considerations to keep in mind when shopping for the best air conditioner cover. From the size to the type and even how they look, these are all important factors.
Size and Coverage
Air conditioners come in different types and sizes, and as such, so do their covers. Most manufacturers will describe their covers’ sizes in terms of height, width, and depth. For window air conditioners, they might describe their covers in terms of energy usage, or British thermal unit size, with general sizes that fit multiple AC units. These models typically have drawstrings that you can cinch to hold the cover in place.
Outdoor air conditioning units are slightly different. Outdoor air conditioner covers come in full or partial coverage. Full AC unit covers for winter will envelop the entire AC unit all the way down to its base. Partial covers generally cover just the top of the unit, and they’re often suitable for use while the air conditioner is running. These partial covers can be a big help for folks with lots of trees as they can keep leaves, twigs, seeds, and other debris from collecting inside the unit.
Material
Material is an important factor as well. The air conditioner cover can be waterproof to prevent moisture from penetrating the air conditioner, though this isn’t always necessary. However, it does need to be breathable to prevent trapping moisture inside the unit and to promote airflow.
A breathable air conditioner cover will prevent mold, mildew, and gunk from growing inside the AC unit.
And, since exposure is always an issue, ultraviolet protection is also a plus. There are materials, such as nylon and polyester, which can provide this type of protection, and they sometimes even feature a PVC coating for waterproofing.
For window air conditioner covers or air conditioner covers for winter weather, insulation is key. These models often have layers of foam insulation to keep cold air and drafts from pushing their way into the home. It is important to note, however, that no air conditioning cover will be as effective at keeping out drafts as a closed window.
Mesh material is often all that’s required for partial covers for AC units outside. These mesh air conditioner covers are designed just to keep leaves, twigs, seeds, and other items out of the air conditioner unit—not prevent water penetration.
Installation and Securing the System
AC covers have a reputation for being difficult to install, but that doesn’t have to be the case. Many of the best air conditioner covers simply slide over the top of the air conditioning unit and have hook-and-loop straps that you can adjust to make the fit better.
Securing an air conditioner cover is another story. A window or wall air conditioner cover will typically have drawstrings and elastic bands. An outdoor AC cover may require bungee cords (some kits come with them) to keep it in place. The cord stretches from a metal eyelet in the cover to a slot in the grill of the unit.
Aesthetics
While protection is a cover’s first job, it doesn’t hurt if it looks nice as well. A decorative air conditioner cover might feature interesting patterns and color choices, and some even match patio furniture covers. An outside air conditioner cover can help an outdoor unit blend in rather than stand out like a sore thumb in the spring and fall.
But there isn’t always a handsome solution available. When this is the case, it may be best to go with a simple black full-cover air conditioner cover for outside units or a light-colored insulated interior cover. The basic black cover shouldn’t stand out much and the interior cover can be hidden by curtains.
The Advantages of Using an Air Conditioner Cover
There are debates as to whether air conditioner covers are necessary. However, there are some tried-and-true advantages to using them.
Air conditioner covers keep debris from trees and plants from collecting in the bottom of an air conditioner or in its coils. This ensures that any water that does collect in the bottom of the unit from condensation can evaporate or drain effectively and that the coils won’t clog, requiring less frequent coil cleaning.
Air conditioner covers can also keep pests out of the unit. These pests, if they’re able to infiltrate the unit, can chew wires, bend coils, and cause lots of expensive damage. A cover may keep them out.
Finally, in the case of window units, air conditioner covers keep drafts at bay. A winter air conditioner cover, for example, can lower the home’s energy consumption by keeping warm air in and cold air out.
- Air conditioner covers can keep twigs, leaves, seeds, and other tree and leaf debris out of the unit
- Air conditioner covers can prevent pests from getting into the unit and causing damage
- Interior air conditioner covers can prevent drafts from penetrating the home and letting warm air escape
FAQs
That’s a lot to know about the best air conditioner protection, but there might still be some questions with answers that need uncovering. The following are some of the most frequently asked questions about air conditioner covers.
Yes. If you do not use one, the most likely scenario is that debris, leaves, and seeds will collect in the bottom of the air conditioner and in the coils. This can prevent effective evaporation and cooling, shortening the effective life of the AC unit and increasing the cost to operate it. You might also need more frequent repairs, and those AC repair bills add up.
Most air conditioner covers come in some basic sizes, but you will still want to measure your air conditioner. Measure the height, width, and depth to ensure you find the right cover size. In the case of window units, many covers are one-size-fits-all, but again, it’s helpful to measure and compare sizes.
AC units are designed to withstand outdoor conditions, including rain. But that doesn’t mean they aren’t subject to wear and tear, which can increase when fully exposed to the elements.
Running your air conditioner with the cover can restrict airflow, causing the unit to overheat. It can also cause it to operate inefficiently, leading to higher energy consumption and the unit possibly breaking down.
