As the Starks from the Game of Thrones series always say “Winter is coming”. They say it as a warning because in the winter things die. If you’re looking at your expensive $300+ air conditioner right now and wish it wouldn’t die during the fall and winter, you’re in luck. With the smart use of air conditioner cover during winter, you can easily protect your AC unit from the environmental elements.
The air conditioners provide a refreshing breeze in the summer but if we’re not careful about property storing or protecting them in the fall and winter season, even the most expensive AC units won’t last for 10+ years. For example, through the wall air conditioner covers for winter protect indoor AC units during the winter.
This is true for window and indoor air conditioners, and especially for outdoor AC units. Having an outdoor central air conditioner cover is key to keep the elements away.
We’ve prepared the Top 5 best air conditioner covers lists with reviews so that you’ll be able to protect your AC. There are three sections (you can click on one to jump to that particular list):
|(sometimes referred to as a 'central AC unit' as well)||(inside the house we usually install the AC unit near the window)||(through the wall air conditioner covers for winter)|
Best Outdoor Air Conditioner Cover For Central AC Units
Outdoor AC unit covers protect your AC from:
- Rain and damp environment. You don’t want to see fungi growing inside the AC.
- Falling leaves that can jam your AC and rot in it.
- Corrosion. Especially if the AC unit has scratches where the water can enter.
- Cold temperature. Preventing cold air from leaking into your heated house in the winter will slash your heating bill.
The wall or window air conditioner cover serves to protect a window AC unit is much the same way as the outdoors.

For the outdoor air conditioners, there is just no avoiding weather. It doesn’t matter if you have 9000 BTUs or 25000 BTUs model, the central AC units are right there in the open and the protection with the outdoor AC cover especially during the fall and winter months is of utmost importance.
What to look for when looking for an outdoor cover? The most important factor is the dimensions of the air conditioner cover. A tight fit is the best because it’ll give the elements the minimal possible opening to reach the precious and protected AC unit.
Task for yourself: Measure your outdoor AC unit before buying the cover. When picking the cover, it doesn’t matter if you have a Carrier or Lennox AC. What matters the most is, well, the size or the dimensions of the AC.
The design of central AC cover is also important; you’ll be looking at the cover on your yard for most of the fall and all of the winter, you should at least like the look.
1. Jeacent Central Air Conditioner Covers for Outside Units [Best Seller]
The Jeacent cover is the go-to cover if you have an outdoor air conditioning unit in need of fall and winter protection. The cover is made out of 100% woven polyester fabric, a material that can prolong AC life due to:
- Water-resistance. Especially useful in heavy rain.
- Extreme temperature resistance. The 100% woven PE shows its value when the winter temperatures go subzero.
- UV-resistance. Minimizes the UVA and UVB sunlight effect.
- Minimizes electrical failures. Keeping the water, rotting leaves out of the air conditioner.
One key feature that gives the added value to the Jeacent central AC cover is its natural ventilation system. The cover has several mesh vents that allow airflow within the air conditioner under the cover. This prevents water from condensing inside the AC as well as prevents moisture which could prompt some bacteria or even fungi growth:
Despite being the No. 1 choice to protect your air conditioner, you really have to measure your AC unit before you buy the Jeacent outdoor cover. The Jeacent cover is available in 6 dimensions, for small AC units with 24 inches (Width) x 24 inches (Depth) x 22 inches (Height) to large 36” x 36” x 32”.
When you find the cover dimension that fits your outside air conditioner neatly, you have to install it over your AC before fall/winter. The Jeacent cover is very easy to set up; you get an elastic hem cord to secure the cover on the bottom, at the sides you should use Velcro closure and the outdoor cover comes with adjustable buckle straps which tighten the grip of the cover (for strong winds).
If you’re serious about protecting your outside air conditioner and need the best cover, you can order it here:
2. Premium Covermates Outdoor Air Conditioner Cover [Versatile And Elite]
The Covermates covers have always been known as a luxury type of outdoor covers. In short, it is the most versatile and elite central AC cover you can buy, and it is the only one that satisfied the exquisite taste. Honestly, the high-quality cover like this makes sense only if you have a $500+ outdoor air conditioner.
This elite outdoor cover is not just more thing to keep on your yard that your neighbors will be envious of. The variety of dimensions, and yes even different colors of 300D stock-dyed polyester, can’t be matched in the world of outdoor or any kind of air conditioner covers.
The thick 300D polyester (you can read more about the high-quality 300D polyester at Oxford Fabrics) comes in 4 distinct colors; namely, Green Vinyl, Khaki, Charcoal, and, if you want to be even more lavish, the ultimate 600D Ripstop Black.
On the photo, you can see several features of the Covermates outdoor air conditioner cover that are vital to prolonging the life span of your AC unit. Those include the water-resistant polyester and the covered mesh vents that enable air circulation within the air conditioner under the cover which prevents moisture and bacteria, fungi build up during the fall.
With the 14 available dimensions, you’ll be able to fit and protect the smallest outdoor AC unit as well as the biggest 25,000 BTUs one. This also makes the Covermates most versatile outdoor cover available and it will fit pretty much any Lennox or Carrier air conditioner. You can pick your dimension here and follow the instructions on how to use the elastic hem, buckle straps and snap closure to put the cover over your air conditioner in the yard:
3. Ravenna Square And Round Cover For Central Air Conditioner
Ravenna is one of the best air conditioner covers IF you have a 32″ x 32″ x 30″ (Width x Depth x Height). The key is in the material that is used – the durable woven polyester – which is what most of the patio protecting covers are also made out of.
Here they’ve added the UV-stabilized coating and a water-resistant laminated backing in order to create a material that protects the air condition in your garden or yard best.
As you can see, it would be nice to have a bit more dimensions of the Ravenna square air conditioner cover. The 32-inch x 32-inch x 30-inch can cover a big percentage of outside AC units in the US but not all. If you check out #1 and #2 pick, you’ll find much more available cover dimensions.
However, what makes the Ravenna cover unique is that you can buy a round outdoor air conditioner cover. That’s right, even if you have a round central AC unit in your backyard, you can still protect it during the winter months using one of these:
In order to check if the Ravenna round cover fits the AC outside your house, you have to go measure it. The Ravenna cover will fit perfectly if the diameter of the unit is 34 inches.
If you have a round AC, you should take a meter and measure the diameter (the straight distance from one end to the other end that goes through the center of the top of the unit). If it’s between 32 inches and 36 inches, you can go right ahead and buy the Ravenna cover here:
4. COSFLY Big And Best Budget Air Condition Cover [And Stylish!]
COSFLY is the best budget choice as the Lennox air conditioner cover or the bigger Carrier air conditioner cover. The reason being that both Lennox and Carrier are known to have bigger models of outdoor AC units.
Being the best budget cover, you would think that COSFLY will cut corners, especially on the materials. Nothing can be further from the truth. The COSFLY cover for outside AC units is made out of high-quality 600D polyester that provides both water and UV protection. If you set the air conditioner cover correctly in your backyard, even the snow won’t be able to touch your AC:
Unfortunately, the COSFLY is only available for larger central air conditioners. The minimal dimensions of the cover are 32” x 32” x 36” and the maximum dimensions are 38” x 38” x 40”.
The cover itself is as solid (if not even better) than other outdoor covers on the Top5er list but none has as an affordable price as the COSFLY:
5. Veranda Square Outdoor Lennox Air Conditioner Cover
Veranda cover is in many ways similar to Top5er’s #3 pick; it has only one available dimension but it also has an option for a round cover if you have a round-shaped AC unit.
The square dimensions are the 34-inch x 34-inch x 30 inch which, incidentally, is one of the dimensions Lennox frequently uses when making air conditioners. So it comes naturally that the Veranda can be a cover of choice for Lennox owners.
The Veranda also comes with all the necessary accessories to install it over a Lennox AC with ease. These include the elastic hem for the bottom part of the air conditioner and closure buckle that keeps everything in place even in the case of strong winds.
Moreover, the Veranda cover is quite reasonably priced with a cost of less than $30:
Best Indoor Air Conditioner Cover For AC Units Inside The House
Indoor air conditioner covers differ from outdoor AC units covers in three noticeable areas:
- The dimensions of indoor AC and covers are smaller. Average dimensions are 25-inch width x 17-inch depth x 2.5-inch depth.
- They are designed to protect the air conditioner inside the house against dust build-up, keeps the noise down and helps make the indoor AC more energy efficient. They don’t have to protect the unit against the environmental elements; your house already does that.
- It can be used year-round and you can use the cover even when the air conditioner is turned on. You can just cover the AC during the winter and save yourself wondering how you’re going to store it and re-install it every season.
Especially dust build-up is problematic and can shorten the lifespan of even the best indoor air conditioners. The best fabric that prevents dust particles to enter the air conditioner inside the house is quilted cotton.
The indoor AC units are less exposed to the elements. However, inside the house, there are several dangers that inside AC faces such as mites, fluid spills, bacteria, allergens, pet dander and so on. Having allergen bacteria-infected AC can make nighttime breathing, asthma, and allergies a lot worse.
Note: When denoting the dimensions of AC covers, we follow the Width x Depth x Height measurements. Having a cover that fits your air conditioner well is pretty much the only important thing you have to worry about (and measuring the AC before buying the cover is always advised).
The best indoor air conditioner covers will be at least partly made out of quilted cotton; the No. 2 on Top5er list even has a whole layer of 100% quilted cotton to catch all the dust particles that want to enter and jam your AC.
Again, the important thing when picking an indoor AC cover is the dimensions that should fit your indoor AC unit as close as possible. You can get many different dimensions of inside covers that can fit a 3000 BTU AC up to 15000 BTU unit. They also cover all kinds of indoor air conditioner brands such as Honeywell, Lennox, and Carrier.

1. Jeacent Indoor Air Conditioner Cover With Double Insulation [Best Seller]
Jeacent indoor cover so popular because its simple to install, provides double insulation (including quilted cotton layer) and looks as neutral as possible when covering the air conditioner inside your house.
The double insulation consists of two materials with two distinct functions:
- Polyester layer that prevents the indoor air conditioner to bring in the cold air during the fall/winter season (this is the inside layer facing the air conditioner).
- Quilted cotton layer that prevents dust from entering the insides of the air conditioner (this is the outside layer facing the room – and it looks quite neutral).
The installation of indoor air conditioner cover is even easier than with outdoor cover. You simply flip it over the air conditioner inside your house and the elastic around the edges will tighten the fit and keep the cover from falling off.
The Jeacent is available in 4 different dimensions. The smallest one for 3000 – 5000 BTU air conditioners is 16 inches wide, 13 inches deep and it has a 2.5-inch height. The biggest one that fits the 12000 – 15000 BTU units is 28” x 20” x 2.5”. You can check them all out and pick the one which fits your indoor air conditioner best here:
2. Gerrard Larriett Quilted Indoor Air Conditioner Covers for Window Units [Premium Choice]
The air conditioner cover inside your house will affect your internal design. Luckily the Gerrard Larriett, a brand who knows how important the internal design is, has come up with their over indoor AC covers and they are lavish, to say the least.
Gerrard Larriett has always been a luxury brand with a great sense of style. They’ve created a double insulating cover with 3 layers, each serving its own purpose when it comes to protecting the indoor air conditioner:
The triple layer of 100% quilted cotton, batting, and liner works synergistically to prevent the cold air from entering our house with the air conditioner hose. It proves the air conditioner itself with a block against the dust particles that might settle in the AC unit if it weren’t for the quilted cotton barrier.
The best thing about the Gerrard Larriett is that it offers you a variety of colors and themes like Frozen or Mickey Mouse you can choose from. You have everything from stylish Ivory tones to children themes to even an American flag cover:
These premium covers are most appropriate for middle-sized and big indoor AC units. The dimensions range from 24” x 15” x 4” for middle-sized units to 28” x 20” x 4” for big ones.
You’ll notice that there is a big 4-inch height measurement associated with all Gerrard Larriett covers; those provide you with a better and tighter fit around the AC unit:
3. QUALITYDEPOT Hypoallergenic Dust Mite And Allergy Control Cover [Best Budget]
The QUALITYDEPOT is the best indoor cover for your buck. It comes with the regular double insulation layers; one being made out of polyester and the other one out of meticulous quilted cotton.
It is important to point out that all covers provide people allergic to dust mite and other allergies a breathing space. If you’re allergic, you know that removing everything where the dust might settle is very useful, and the indoor air conditioner is known to create a safe harbor for dust in your house.
That’s why the quilted cotton in the QUALITYDEPOT air conditioner cover for inside the house is so important. It filters out all the dust particles that might otherwise enter the AC unit and be sprayed out as soon as you turn on the air conditioner.
There are 3 available dimensions for small-sized and medium indoor AC units. The smallest one has measurements of 17” x 13” x 2.5” and the biggest one has dimension of 25” x 17” x 2.5”. You can order them here:

The double insulation with polyester and quilted cotton provides the internal air condition with protection against dust and also keeps the cold air that might come in your house via the AC hose out.
It’s a sweet little cover with a diamond shape stitch pattern that fits nicely with the existing interior design. Here’s one example of how the installed air conditioner cover looks in a room:
It also costs less than $10 and usually comes with free shipping:
5. Sturdy Covers Big Indoor AC Unit Cover
The Sturdy Covers cover has some surprising features. The type of polyester used on the internal insulation side (the one facing the AC) is 210 PU which is great at repelling the cold winter air that could sip inside your house via the air conditioner hose. The effective insulation helps you preserve heat during the winter and slashes the electricity bill.
This cover is made mostly for big indoor air conditioner units (usually mounted near the window) with 12000 BTU or even 15000 BTU:
The biggest available dimensions measure 28” x 20” with the full 4-inch thickness (or height). You can see from the photo above how well those 4 inches surround the air conditioner’s vents.
Additionally, you can pick between the white and black color, depending on which one will fit your internal design better:
Best Wall Air Conditioner Cover For Wall-Mounted Outdoor AC
There are two main purposes that point out why we need a cover for the outdoor wall air conditioner:
- To protect AC against the elements and prolong its lifespan (the obvious reason). Think rain, snow, leaves, grass, even birds nesting.
- To prevent drafts (less obvious reason). The cold air can enter the wall air conditioner and through a hose enter into our house since the AC unit and the one inside the house are connected.
Prolonging the lifespan of wall-mounted air conditioners is just plain hygiene; why would you not protect a $300+ worth of sophisticated equipment?
The less obvious reason why to cover a wall air conditioner is the drafts. In the winter, the cold weather outside can enter our house and raise the heating bill quite a bit if we have to constantly fight off the cold air.
Again, when choosing the wall-mounted AC cover it doesn’t matter that much if you have a Lennox or Carrier unit. What matters the most are the measurements; so do measure your wall air conditioner before buying a cover:
|Window AC Cover:||AC Defender Wall AC Cover||iSOLe Wall AC Unit Cover||Jeacent Wall AC Cover||LBG Products Heavy Duty Wall AC Cover||Foozet Small Window AC Cover|

- Protection against the weather. Its heavy-duty design with the thick 600D polyester exterior is designed to withstand the strongest storms, rainfalls, winds, and snows. The double strap buckle also fixes the cover to the wall air conditioner tightly.
- Completely prevents drafts. To completely prevent the cold air from entering the house via AC hose, you mustn’t leave air openings between the cover and the AC, and the cover fabric has to be as insulting as possible.
The AC Defender uses the two-buckle system instead of a one-buckle system to strap the cover over the air conditioner as tightly as possible, leaving no openings for the cold air to leak in.
