Should You Cover Your AC Unit for the Winter?

One of the most common questions homeowners ask us this time of year is: “Should I cover my AC unit for the winter?” The short answer: usually not.

Why You Don’t Need a Cover

Most outdoor AC units are designed to withstand harsh conditions like snow, ice, and freezing temperatures. Adding a cover may actually do more harm than good:

  • Traps moisture – leading to mold and mildew.
  • Invites pests – small animals may nest inside, chew wires, or cause damage.

When a Little Protection Helps

The one exception is if your unit sits under trees or in an area where debris can fall. In that case, you don’t need a full cover. Instead:

  • Place a piece of plywood on top of the unit.
  • This shields it from branches and leaves while still allowing airflow.

Better Ways to Protect Your AC

Instead of covering your system, focus on regular maintenance:

  • Clear away leaves and debris.
  • Check the coil and surrounding area.
  • Schedule a yearly AC inspection with a professional to ensure your system is running smoothly.

The Bottom Line

Covering your AC unit for the winter is optional, but caring for it is essential. A little maintenance now can save you from costly repairs later.
