A good cover not only extends the life of the unit but also improves energy efficiency. It prevents dust, debris, and moisture from entering, which can lead to costly repairs down the line.
Types of Covers Available
When I started looking for covers, I found that they come in various materials. Some of the common options include vinyl, canvas, and polyester. Each material has its advantages.
