Do I Need to Cover My Air Conditioner?

With cold weather coming in Lincoln, 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 created to take on bad weather, including extreme temperatures and torrential precipitation.

Sometimes covers cause more problems, because they can trap water. Too much wetness inside your equipment can cause internal components to rust or get moldy.

While putting on an air conditioner cover is a personal choice, there are two periods that are great for using a cover for an extended period of time—fall and summer.  

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

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from AW Heating & Air Conditioning heating and cooling professionals can help. We’ll clean and lubricate your unit, and inspect essential pieces. This often allows us to spot issues 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 choosing the ideal cover. 

Avoid Full Covers

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

Full AC covers can trap condensation inside your unit, potentially rusting metal parts. It could also make your AC an inviting home for vermin, which could chew wires.

Plastic or vinyl covers block air, which could cause moisture 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 heavy snow is approaching. Snow and ice that accumulate inside your AC can melt and refreeze, harming condenser coils and reducing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your AC if a strong storm is coming in Lincoln. Hail can critically damage your system’s fins, altering efficiency.
