Introduction to Window AC Unit Covers

When winter arrives, I realize it’s essential to protect my window air conditioning unit from harsh weather elements. A window AC unit cover helps in preventing drafts, moisture, and debris from damaging the unit. I’ve learned that selecting the right cover can significantly extend the life of my AC.
