Covering your AC unit for the winter can protect it from harsh weather conditions. While the compressor and other components are shielded by a durable shell, falling leaves, snow, ice, cold, dirt, and even rodents and other small animals can cause problems with your outdoor air conditioning unit. Fortunately, you can find an air conditioner cover at most hardware stores. But there are many styles, materials, and sizes available. Here’s a look at how to choose air conditioner covers for winter to protect your AC unit.


Types of AC Covers

There are many things to protect your air conditioner from. In some environments, it may be snow and ice; in other places, rocks, grass, or seeds may be problematic. Some of the most common types of covers include:

  • Mesh: Maintains airflow but resists debris and moisture, as well as protects against rust and corrosion by preventing snow or rain from accumulating on the unit.
  • Top-Only: Depending on the unit and location, you may only need to protect it from the top; a top cover is easy to install and protects vital electrical/mechanical components.
  • Woven Polyester: Fabric covers come in different colors and are effective at protecting AC units, while being easy to put on and remove.

These aren’t the only covers that are available. There are also insulated, armor-plated, and adjustable covers. And if it’s a window unit instead of an AC outdoor unit cover, there are options to protect your window AC as well.


Tips for Using an AC Cover

An outdoor AC cover is a good idea if there’s often debris around your home, especially in a dry climate. Winter storms can be problematic as well. The best AC covers have a breathable material. This is often preferred because plastic can trap moisture. If you use plywood, place it only on top of the unit to protect components such as the fan from debris.


Should I Cover My AC in the Winter?

Covering your air conditioner unit can have many advantages. It can prevent AC coils from getting dirty, which can reduce efficiency. Another benefit is the cover keeps debris like leaves and twigs from getting trapped inside. If water comes in contact with the coils, it can freeze and cause serious damage.

However, using a cover in the wrong way can lead to rust and corrosion. If it’s not used properly, or you select the wrong one, it can actually trap moisture, which can lead to mold or coil damage. Dirt can still get in if you accidentally turn the unit on with the cover attached. If you’re installing a cover to protect the unit against snow, ice, and cold, check whether your AC is designed to tolerate winter weather. Many newer outdoor units are built to resist such conditions (with or without a cover).
