Do I Need to Cover My Air Conditioner?

With cold weather on the horizon in Front Royal, 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 created to take on severe weather, including excessive temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap condensation. Additional wetness inside your system can cause internal pieces to rust or get moldy.

While installing an air conditioner cover is your own 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 rubbish during those seasons—grass clippings, twigs and leaves—can build up and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more power to cool your home.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few suggestions on choosing the right cover. 

Avoid Full Covers

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

Total AC covers can trap condensation inside your equipment, potentially eating away at metal parts. It could also make your air conditioner a cozy place for rodents, which could eat through wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know heavy snow is coming. Snow and ice that collect inside your AC can melt and refreeze, harming condenser coils and reducing efficiency.
