Should I Cover my Air Conditioner After Summer?

Snow on AC

As the winter months start to set in, many homeowners wonder if their AC unit needs to be covered. The only time you should cover your air conditioner is during the fall. AC units are built to withstand rain and snow, but not leaves, seeds and nuts.

But why don't you need to cover it in the winter?

Many people are under the impression that a cover will protect the AC from dirt, snow/ice and moisture. Your unit only sucks in air when it is on, bringing in dirt and other debris. Once off, no dirt or debris will enter your home.

Since AC units are already built to withstand snow/ice, a cover is unnecessary during the winter. Additionally, having a cover on your AC can trap moisture, which can lead to mold.

A cover on your air conditioner can also attract rodents and other small animals. As the cold weather sets in, animals looking for warmth might make your cover their new winter home.
