Why Do You Need An Air Conditioner Cover?

Truth be told, there is always a probability you do not need one. Depending on how the climate is in your area, your air conditioning unit can be safe outside, all year long. Things get a bit more complicated and extra-care becomes essential if winter’s freezing.

So, one reason why you may need an air conditioner cover is to protect your unit from excessive moisture. For those of you living in areas where winter equals heavy snowfall or rain, prevention is key. Having snow or water infiltrating among your AC’s circuits is far from desirable. An adequate cover allows proper airflow and keeps excessive humidity under control. This way, your unit’s integrity and performance are for more years.

Another threat that lurks around the house and can cause damage to your AC are small animals. From mice to other tiny creatures, there are plenty of potential unwanted inhabitants. Nesting inside the exterior component of your air conditioner is already bad enough. Now imagine how things get worse, as these animals can start chewing on wires. You’d have to replace components all the time and cover unwanted costs. A suitable cover can block the access ways for rodents and other animals, to prevent them from making a nest.

One more aspect that can weigh in on your decision of covering your AC unit. Spending a consistent amount of money on a cooling system for your home means you want to avoid extra costs. To prolong its well-functioning and prevent unnecessary complications, a cover can be useful. Of course, you need to make sure the cover does more good than damage. And for that, keep reading our tips and recommendations below.

What Features To Look For In An Air Conditioner Cover?

With such a controversial topic, getting the best air conditioner cover can be tricky. If you decide to get this type of protection for your cooling unit, you need to know what to look for.

The quality of the material is the top of the list. Your air conditioner cover should be capable of facing all the weather extremities. From rain, strong wind or a lot of dust, down to strong UV radiation, you name it. Your AC is, by design, made to survive exterior factors like rain or sun heat. But if the climate in your area takes things up a notch, a cover can diminish the weather’s rage. On the other hand, the material should also be porous enough to allow a proper airflow through the AC unit. You don’t want to avoid the rain from coming in, nor the mold to grow inside.

Another aspect you should look for is the reliability of the cover. Check what kind of locking system it features and how secure it is. Consider any downsides that might derive from this. As an example, if your air conditioner cover uses metallic components, these can be prone to rust. Or in case of very strong winds, any movement of the metallic rings or cords can scratch or damage the AC exterior. As we mentioned, you want this cover to help you protect, no cause more trouble for your cooling device.

Aesthetics are another important detail to keep in mind. Decide if you want the air conditioner cover to be a mere complementary accessory or not. Most homeowners prefer this to easily blend in with the outside decorations. So, you should avoid compromising for a cheaper AC cover unless you’re willing to take that risk. Having an element that sticks out like a sore thumb can really ruin the mojo in your patio.

Size matters, in this case, as what is too much can lead to unwanted complications. Make sure to get a cover that is slightly smaller than the cabinet of your AC. This way, you know the interior of the unit still gets enough airflow. So mildew does not grow incessantly and the air pipes don’t get contaminated.

Verify the difficulty associated with the installation process. As easy at it may seem at first sight, putting on an air conditioner cover can easily escalate into a chore. Opt for a simple, easy to install version, if you don’t want to spend hours figuring out how to assemble it.

Check for covers that include a long-term warranty. It is the manufacturer’s promise of quality and saves you from the hassle of extra costs in extreme cases. Plus, you don’t want to be buying a new cover every year. A worthy investment should keep your AC cabinet protected for a few years.

Air Conditioner Cover – Benefits vs Drawbacks

Still, have some doubts about covering your air conditioner unit? Perhaps a quick overview of the main benefits and drawbacks will help you clear them.


  • Extended life expectancy for your air conditioner

A cover ensures a better, prolonged performance for your AC unit. And it also keeps the cabinet looking as good as new, even after many seasons of using.

  • Increased efficiency for your air conditioner

Keeping dirt, moisture or bugs out, an air conditioner cover protects the coil element. With a cleaner inside, your cooling unit can give its best results at any moment, even at the start of the season.

  • Decreased costs for upkeeping

Less debris or moisture equals less malfunctions in your air conditioner. By using a proper cover, you can prevent additional costs for unwanted repairs. Keeping your unit protected helps you save money, by avoiding glitches.


  • The inappropriate covering can trap moisture.

If you completely cover the unit and airflow is poor, rust and corrosion can attack from the inside. Excessive moisture can affect the integrity of the electrical wiring or circuit boards. Mold and mildew also thrive in conditions of high humidity. If mold infiltrates in your air conditioner, it can block the evaporator coils. Not to mention it will make its way inside your home and contaminate the air you breathe.

  • A completely sealed unit welcomes rodents.

Having your AC unit covered can seem as an invitation for rodents or other small animals to nest inside. This is not as cute as it may sound, since these animals can chew the wires and other components of your unit. Not to mention how damaging their debris can be for the internal elements.

  • An air conditioner cover is an additional cost.

If you don’t have the budget to get a high-quality cover from the first time, you can end up in a vicious circle. You may have to get a new cover year after year, to replace the faulty one. And this extra cost is something you may not actually want or be able to afford.

Final Considerations

Getting an air conditioner cover is a controversial move. It can prove highly beneficial for your unit, if it has to face extreme weather conditions. However, many manufacturers do not necessarily recommend it. If you use the air conditioner all year round, then it is, for sure, built to withstand all weather challenges.
