Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Lodi, you may be questioning 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 excessive temperatures and relentless precipitation.

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

While using an air conditioner cover is an individual choice, there are two periods that are ideal 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 accumulate and block your system’s airflow. Decreased airflow means your air conditioning unit works more and may use more energy to cool your home.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Tokay Heating and Air Conditioning heating and cooling experts can help. We’ll clean and lubricate your unit, and take a close look at critical parts. This often allows us to pinpoint trouble before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Full AC covers can trap condensation inside your system, potentially eating away at metal pieces. It could also make your air conditioner a welcoming area for vermin, which could chew 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, harming condenser coils and decreasing efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your air conditioner if a bad storm is approaching in Lodi. Hail can severely damage your system’s exterior, impacting efficiency.
