Do I Need to Cover My Air Conditioner?

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

Your AC unit is a tough piece of equipment. It’s engineered to withstand inclement weather, including extreme temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Too much wetness inside your system can cause internal components to rust or turn moldy.

While putting on an air conditioner cover is a personal choice, there are two seasons that are good to use 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 lower 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? Routine AC maintenance from McFadden Heating & Cooling heating and cooling professionals can help. We’ll clean and lubricate your system, and inspect essential pieces. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Full AC covers can trap moisture inside your equipment, potentially eating away at metal pieces. It could also make your system a welcoming area for rodents, which could sever wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers stop air, which could cause moisture to build up inside your air conditioner. The best type of cloth is one that allows airflow, like canvas or mesh.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a blizzard is on the way. Snow and ice that accumulate inside your AC can melt and refreeze, breaking condenser coils and lowering efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your air conditioner if a strong storm is imminent in Dresden. Hail can severely damage your system’s coils, altering efficiency.
