With cold weather on the horizon in Des Moines, you may be thinking when you should cover your outdoor air conditioner. Of if you should even cover it at all.
Your AC unit is a sturdy piece of equipment. It’s engineered to resist bad weather, including extreme temperatures and relentless precipitation.
Sometimes covers create more issues because they can trap moisture. Additional wetness inside your unit can cause internal parts to rust or get moldy.
While using an air conditioner cover is your own choice, there are two times of year that are ideal for using a cover for an extended period of time—fall and summer.
That’s because yard rubbish during those seasons—grass clippings, twigs and leaves—can pile up and obstruct your system’s airflow. Reduced airflow means your air conditioning unit works longer and may use more electricity to cool your house.
Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Heartland Heating & Cooling heating and cooling professionals can help. We’ll clean and lubricate your unit, and inspect essential components. This often allows us to pinpoint trouble before they begin.
How to Find Your Air Conditioner Cover
If you come to the conclusion you want to cover your air conditioner, here are several ideas on choosing the ideal cover.
Avoid Full Covers
To keep air moving, a protective air conditioner cover should only enclose the top of your system and a couple of inches on the side.
Complete AC covers can trap moisture inside your equipment, potentially eating away at metal components. It could also make your AC a welcoming area for rodents, which could chew wires.

Cover Your Air Conditioner Before Severe Weather
You can temporarily cover your air conditioner in the winter when you know heavy snow is on the way. Snow and ice that collect inside your system can melt and refreeze, breaking condenser coils and decreasing efficiency.
Although it’s not always possible to expect a hailstorm, you can temporarily cover your AC if a severe storm is imminent in Des Moines. Hail can critically damage your system’s fins, affecting efficiency.
