Do I Need to Cover My Air Conditioner?

With cold weather on the horizon in Marshfield, 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 strong piece of equipment. It’s designed to resist inclement weather, including intense temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap moisture. Extra wetness inside your unit can cause internal parts to rust or get moldy.

While installing an air conditioner cover is an individual choice, there are two times of year that are great for using a cover for a long period of time—fall and summer.  

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can build up and lower your system’s airflow. Reduced airflow means your air conditioning unit works longer and may use more power to cool your home.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from House of Heating Incorporated heating and cooling technicians can help. We’ll clean and lubricate your system, and take a close look at important components. This often allows us to spot problems before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are several tips on picking the best cover. 

Avoid Full Covers

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

Total AC covers can trap condensation inside your equipment, potentially corroding metal parts. It could also make your air conditioner a welcoming 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 a blizzard is approaching. Snow and ice that collect inside your air conditioner can melt and refreeze, damaging condenser coils and lowering efficiency.
