Understanding the Need for Indoor AC Covers

When I first considered buying an indoor air conditioner cover, I realized that protecting my AC unit was just as important as keeping it clean. An indoor cover helps shield the unit from dust, pet hair, and other debris, which can accumulate during the off-season.
