Risks and Considerations
Covering your air conditioner can be a great way to protect it from the elements, but it's not without its risks. Moisture can seep in and cause mold, mildew, rust, and corrosion if you use a non-breathable cover.
If you live in an area with heavy rain and snow, it's essential to choose a breathable cover with side vents to allow for proper ventilation and airflow. This will help moisture evaporate before it causes any damage.

Damaging your unit is a real concern if you don't shut off your air conditioner when it's covered. If the cover is left on while the unit runs, the copper coils inside won't cool down, causing hot air to be pushed back into your home and potentially leading to overheating and breakdown.

Why Cover Your AC in Summer
Covering your air conditioner in the summer can provide an extra layer of protection from debris falling from gutters or trees. A mesh cover is a good option as it allows for proper airflow and can be left on while the unit is running.
Mesh covers also protect your air conditioner from the sun, which is beneficial for keeping it looking like new and running efficiently. In fact, using a mesh cover can help your air conditioner keep your house cooler, making its job of cooling easier.
If you live in an area prone to hailstorms, an Armor Top Cover with four armor plates sewn into the top may be a better choice. These covers provide better UV ray protection than mesh top covers.
Using a top air conditioner cover won't provide as much protection, but it's typically not a problem during spring and summer. However, if you expect a severe storm or rarely turn on the AC, a full air conditioner cover may be a good option.

Risks of Covering an Air Conditioner
Covering your air conditioner can be a great way to protect it from the elements, but there are some risks to be aware of. Using a non-breathable cover can lead to mold, mildew, rust, and corrosion.
Moisture can get into the unit even when it's covered, especially if you live in an area with heavy rain and snow. This can cause serious damage over time.
Choosing a breathable cover with side vents is key to preventing these issues. It allows for proper ventilation and airflow, so moisture can evaporate quickly.
Some air conditioners also function as heat pumps for your home, which can be a problem if you cover them. If you're not sure, check the paperwork that came with your unit or contact the manufacturer for more details.
Another danger is if your AC unit turns on while covered. This can cause the copper coils to overheat and break down.
To avoid this, shut off your air conditioner when it's covered. You can also use the outside power shutoff near the condenser to prevent it from coming on, even if you adjust the thermostat.

What to Consider When Buying an AC Cover

Before buying an AC cover, consider your local climate. If you live in an area with harsh winters, you'll want a cover that can withstand the elements.
Look for a cover that's breathable and water-resistant, as these are the most important features to consider. Waterproof covers don't exist, so it's essential to find one that allows moisture to evaporate.
Trapped moisture can lead to mold, mildew, rust, and corrosion, which can damage your air conditioner. Non-breathable covers are usually made of plastic, so opt for one made of commercial-grade vinyl or high-quality polyester instead.
Mesh vents are a must if you're looking to cover your entire unit. They allow for airflow and prevent moisture buildup.
Measuring your air conditioner accurately is crucial to finding a cover that fits correctly. If you can't find a cover that matches your exact dimensions, look for one that's a little larger with adjustable features like a drawcord, elastic hem, and/or buckle straps.
Alternatives and Solutions
If you're facing a hailstorm or blizzard without a cover, placing plywood on top of your air conditioner and weighing it down with bricks or rocks can be a quick fix. This method won't damage your unit, as plywood is breathable enough to prevent mold and mildew.
You can also use a screen to hide your air conditioner, which is especially useful if you live in a mild climate. These screens block debris that the wind blows in from the sides, but don't cover the top of the unit.
Pairing a top AC cover with a screen is an attractive and protective solution for your outdoor air conditioner, making your yard look neat and tidy.

Solutions Instead of a Cover
If you're facing a hailstorm or blizzard, you can place plywood on top of your air conditioner and weigh it down with bricks or rocks to keep it in place. This will prevent damage from above, and as soon as the storm is over, you can brush off the snow and ice and remove the plywood.

You can also use a trash bag and some duct tape to cover your air conditioner in the winter. Simply place the bag over the top and secure it with duct tape, making sure to leave some ventilation on the sides to prevent moisture buildup.
In some areas, like upstate New York, air conditioners are designed to withstand harsh winters and don't require covering. However, in other places, covering the top 1/4 to 1/2 of the unit can help prevent moisture from entering and causing damage.
Using a screen to hide your air conditioner is another option, but keep in mind that it won't provide complete protection from the elements. If you live in a mild climate, you can pair a top AC cover with a screen for added protection.
