Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Perry, you may be wondering when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a strong piece of equipment. It’s engineered to take on severe weather, including intense temperatures and torrential precipitation.

Sometimes covers create more issues, because they can trap condensation. Additional wetness inside your unit can cause internal parts to rust or become moldy.

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

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can pile up and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works more and may use more energy to cool your home.

Looking for other ways to make your air conditioner run efficiently? Annual AC maintenance from Gillman Heating and Air heating and cooling experts can help. We’ll clean and lubricate your equipment, and examine important parts. This often allows us to spot problems before they begin.

How to Choose an Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are several ideas on selecting the right cover. 

Avoid Full Covers

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

Total AC covers can trap condensation inside your unit, potentially rusting metal components. It could also make your air conditioner an inviting area for animals, which could eat through wires.

Plastic or vinyl covers impede air, which could cause condensation to build up inside your unit. The best type of cloth is one that’s breathable, 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 snowstorm is on the way. Snow and ice that collect inside your system can melt and refreeze, breaking condenser coils and lowering efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your system if a strong storm is coming in Perry. Hail can severely damage your system’s exterior, affecting efficiency.
