If you find your air conditioner is under a constant barrage of leaves, pine needles or debris – or even just a few leaves getting in the unit now and again, don’t ignore it. This is a serious risk and can lead to significant damage unless you take steps to protect your AC.

The good news is that the Sturdy Covers Mesh AC Defender does exactly what the name suggests – defends the air conditioner with a PVC-coated mesh, that covers it from top to bottom. The unique mesh design and the moisture-resistant material guarantee airflow and prevent rain or snow accumulation, thus protecting from rust or corrosion.

The Sturdy Covers Mesh AC Defender comes in three sizes, can be used in any season and will stay in place even in especially windy days.

Available sizes:

  • 28W x 28L x 32H
  • 32W x 32L x 36H

Simply fasten them in place to each side of the unit and you can forget about the cover altogether. It will do its job all year round, protecting the AC from leaves or grass clippings and will keep moisture at bay, keeping all electrical components dry.

The best thing about the Sturdy Covers Universal Mesh AC Defender is that it can be used with a huge variety of AC units. It comes in three sizes (28×28 inches, 32×32 inches, 36×36 inches), so as long as you measure the air conditioner carefully and since this is a top cover only, you should have no problems in selecting the perfect fit.

There is a reason the window air conditioner is one of the most common types of AC – quick and easy to install, convenient and often the best option on a budget. There are however a few drawbacks, most annoyingly cold drafts in the winter. A durable and well-fitting cover can not only protect your unit from rain and snow which can lead to corrosion, but also stop dust, dirt and winter air getting into your home.

The Sturdy Covers Window Unit Defender is an excellent choice, once you don’t need the AC working with winter approaching. A heavy-duty waterproof 600D polyester construction with two adjustable straps to keep it in place regardless of the weather, the cover is available in three sizes, to fit most standard-size window units. This window unit defender will keep you comfortable in the winter and will prolong the life of your air conditioner.

Available sizes:

  • 15H x 21W x 16D
  • 17H x 25W x 21D

Protecting your air conditioner in the winter doesn’t have to be an ugly affair and a makeshift cover from an old tarp and some bungee cords will not look – or work – very well. The Jeacent Central Air Conditioner Cover on the other side is a 100% woven polyester fabric in a beautiful chocolate color, that will protect the AC unit from dirt, rain and sun.

A quick reminder: this type of full cover cannot be left on the unit once it is turned on. It is however really easy to put on and take off, thanks to an elastic hem around the bottom, simple click-close straps and a Velcro closed slit on the side, to allow for the tubes and wires. A nice touch is that the mesh vents double as hidden padded handles – not only do they keep moisture from getting trapped inside the cover, but make removal a breeze.

Available sizes:

  • 24″L x 24″W x 22″H
  • 24″L x 24″W x 30″H
  • 26″L x 26″W x 32″H

Buyers Guide

How to winterize an air conditioner?

In the long summer days and nights your trusted air conditioner keeps you cool and comfortable, working away in the background, pretty much ignored but definitely appreciated. Let’s be honest, we only notice our AC units if they stop working. And in the winter we pay them even less attention but the truth is, as sturdy as your air conditioner is, it still needs protection in order to work as long as possible. In order to winterize it, select the optimal cover depending on your climate and make sure your AC unit – and therefore your home or workplace – is protected.

Should you cover your air conditioner?

Many people prefer not to cover their air conditioner or simply don’t think about it but if you live in a climate with distinct seasons, you might want to think about protecting the unit. Maintenance in the spring is very important and your job will be so much easier if the air conditioner is in good shape, without any damage or debris. In case you think throwing any old tarp or a DIY cover on will do the trick, think again – sometimes a makeshift solution will do more harm than good. Most of these homemade covers will not be breathable and water might get trapped inside, causing mold and mildew to grow.

Should I cover my air conditioner in winter?

Often people don’t cover their air conditioners in the winter, thinking that since the unit can withstand rain and snow, it can take anything bad weather can throw at it. Unfortunately, this is not necessarily the case. Fluctuating temperature means water melting and freezing again which can ruin the condenser coils and falling icicles can seriously damage the AC unit so keep an eye on the forecast.

Of course, depending on where you live, you might not even remember what winter is. In that case, your air conditioner is probably working overtime to keep you nice and cool, lucky you.

What materials and features to look for?

When selecting a cover for your air conditioner, always look for a few key features that will guarantee your unit is really protected, especially against moisture. Instead of placing your trust in the so-called “waterproof” covers that will most likely trap water and lead to all sorts of damage, look for water-resistant, breathable and durable materials which allow air to circulate and condensation to evaporate. The best fabric covers will have mesh vents to improve ventilation, adjustable straps to keep the cover securely in place and Velcro slits to fit around hoses and wires.

How to measure your air conditioner for the right cover?

Before you purchase a cover, make sure you have measured your air conditioner properly – there’s no point in getting something that won’t fit.

Buying the right cover means not only selecting the type that best fits your climate, but also measuring accurately and getting the most appropriate size.

measuring instructions

For width measure left to right (across the front of the unit), for depth measure back to front and for height from the bottom to the top.

Round up to the nearest inch if you must but keep in mind, if for some reason you can’t find a cover with the perfect dimensions, you should get one that is slightly larger or a custom made order.

Should I run my AC with a cover on top?

Depending on the location some air conditioners should be covered in fall and winter, others only for severe storms (especially if there is no actual fall or winter where you live). Keep in mind that some types of covers can be left on while the unit is running but others have to be used only when the AC is not working.

For example, if you are using a full cover on your outdoor air conditioner or an armor top cover, you cannot leave it on while the machine is switched on. But if yours is a mesh top cover, it can be safely left on.

What type of cover should I buy?

The type of cover you should get depends on your needs and the type of air conditioner you have.

If yours is a window-mounted or a wall AC unit, keep in mind these are not as sturdy as the outdoor kind and could use an indoor cover, which prevents dust and dirt damaging the unit and keeps drafts at a minimum during the winter.

For an outdoor air conditioner, you can get a full cover or just a top cover (which can be a mesh or an armor cover). These are pretty much what it says on the tin – the full cover completely envelops the unit, while the top protects from falling debris, leaves and the like.

Should I cover my air conditioner during fall?

Covering your air conditioner in the fall is equally as important, if not more, than protecting it in the winter, since it is not only the weather you need to worry about – leaves, debris and rodents can damage the unit while it is not working.

Sometimes leaves and other debris can enter the AC system from the top.

Leaves can and most likely will gather around and inside the air conditioner and that can trap moisture, which leads to corrosion and mold. Also, once temperatures drop, small animals start looking for warm and sheltered places to make their home and any wiring or other parts they can chew on. You might not even realize you have new tenants before you try to switch the AC on… and fail.
