Do I Need to Cover My Air Conditioner?

With cold weather approaching in Hickory, you may be questioning when you should cover your outdoor air conditioner. Of if you should even cover it at all.

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

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

While using an air conditioner cover is your own choice, there are two seasons that are ideal for using a cover for an extended period of time—fall and summer.  

That’s because yard waste 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 harder and may use more power to cool your house.

Seeking other ways to make your air conditioner run efficiently? Routine AC maintenance from Climate Control Systems heating and cooling experts can help. We’ll clean and lubricate your system, and inspect critical pieces. This often allows us to spot trouble before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a couple suggestions on picking the right cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your system, potentially eating away at metal components. It could also make your system an inviting area for vermin, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers block air, which could cause condensation to build up inside your system. 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 coming. Snow and ice that accumulate inside your air conditioner can melt and refreeze, damaging condenser coils and lowering efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your system if a bad storm is imminent in Hickory. Hail can severely damage your system’s coils, impacting efficiency.
