Pros & Cons to Covering Your AC Unit in the Winter

Air conditioning units are made with materials capable of handling winter weather and have built-in drainage to get rid of winter precipitation and snow melt, so contrary to what you may think, most outdoor AC units don't actually need the protection of a cover during winter months.

Think of your air conditioner as the radiator on your car. Snow and water is not going to affect the coils. All of the electric parts are covered inside your unit with a sealed cover.

In the fall if you have problems with an abundance of leaves, you could think about covering just the top. This will keep leaves, twigs, nuts and other falling debris from getting into the unit which can cause problems down the line. But, if you decide to cover the entire unit, keep in mind you are creating the perfect cozy environment for mice and other small critters to make a home. They tend to damage the AC unit by chewing on wires.

Another negative to covering your whole unit is trapping moisture. Steel painted parts aren’t rust proof. They will rust along with the mechanical parts inside the unit.

Our conclusion, don’t cover your AC unit for the winter months. Have your HVAC checked routinely and enjoy one less thing to worry about on your fall cleaning checklist!
