Frequently Asked Questions
Is It Good to Cover Your AC Unit?
If you have a removable window unit, it’s best to take it out and store it inside for the season. But if that’s not an option, you can buy two covers for both sides: a cover for the outside to protect from pests and pollen, and another cover for the inside to protect from drafts.
If you have central air, experts suggest covering up your outdoor AC compressor unit in the autumn only, not in the winter, unless you choose a mesh design. Since new HVAC units are built to hold up to the elements, covering it in the winter could do more harm than good, leading to trapped moisture, mold, and rust. However, covering the unit in the fall may help keep leaves, twigs, and other autumn debris from getting into the unit.
What Can I Cover My AC Unit With?
If you are going to cover your air conditioner, it’s best to purchase a professionally-made cover. Don’t use drop cloths or tarps to cover the outside portion of your AC unit. You want to make sure the cover is breathable, and not made of plastic so that rusting does not occur. Make sure it has a good fit and repels moisture, and that it is properly installed according to the product’s instructions.
