With cold weather approaching in Dresden, you may be thinking when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a sturdy piece of equipment. It’s engineered to resist bad weather, including intense temperatures and torrential precipitation.

Sometimes covers do more harm than good because they can trap moisture. Extra wetness inside your unit can cause internal components to rust or become moldy.

While using an air conditioner cover is a personal choice, there are two seasons that are good to use a cover for a lengthy period of time—fall and summer.

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can accumulate and obstruct your system’s airflow. Diminished airflow means your air conditioning unit works harder and may use more electricity to cool your house.

Seeking other ways to make your air conditioner run efficiently? Annual AC maintenance from McFadden Heating & Cooling heating and cooling experts can help. We’ll clean and lubricate your system, and take a close look at important parts. This often allows us to spot problems before they begin.

Choosing the Right Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple suggestions on selecting the ideal cover.

Avoid Full Covers

To keep air flowing, a protective air conditioner cover should only encompass the top of your unit and a couple of inches on the side.

Complete AC covers can trap condensation inside your unit, potentially rusting metal parts. It could also make your system an inviting place for vermin, which could chew wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a blizzard is coming. Snow and ice that collect inside your system can melt and refreeze, damaging condenser coils and decreasing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your air conditioner if a severe storm is coming in Dresden. Hail can severely damage your system’s exterior, impacting efficiency.
