Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Franklin, you may be wondering when you should cover your outdoor air conditioner. Of if you have to cover it at all.

Your AC unit is a tough piece of equipment. It’s engineered to take on inclement weather, including extreme temperatures and relentless precipitation.

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

While putting on an air conditioner cover is a personal choice, there are two times of year that are ideal for using a cover for a long period of time—fall and summer.  

That’s because yard rubbish during those seasons—grass clippings, twigs and leaves—can pile up and lower your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more energy to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Winters Heating and Cooling heating and cooling professionals 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 come to the conclusion you want to cover your air conditioner, here are a few suggestions on picking the ideal 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.

Full AC covers can trap condensation inside your system, potentially rusting metal pieces. It could also make your air conditioner a welcoming area for animals, which could chew wires.

Cover Your Air Conditioner Before Severe Weather
