Should you cover your AC unit in the months that you're not running your AC?

Air Conditioning Cover

Here's why we recommend that you don't. It will trap moisture inside, leading to potential damage like rust, mold growth, and reduced airflow, which can harm the unit over time; most experts recommend leaving your AC unit uncovered unless you need to protect it from large debris with a mesh top cover only.

Key points about covering your AC unit:

  • Moisture trapping:

    The biggest concern with AC covers is that they trap moisture inside the unit, which can lead to corrosion and mold growth.

  • Reduced airflow:

    Covers can restrict airflow, causing the unit to work harder and potentially overheat.

  • Pest haven:

    A covered unit can provide a sheltered space for pests like rodents to nestle.

  • Design for outdoors:

    Modern AC units are designed to withstand outdoor weather conditions, so they generally don't need a full cover.

When might a partial cover be okay?

  • Falling debris:

    If your AC unit is located under a tree with lots of falling leaves or debris, a loose mesh cover on top can protect it from large items getting inside.
