Do I Need to Cover My Air Conditioner?

With cold weather approaching in Mobile, you may be wondering 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 designed to withstand inclement weather, including excessive temperatures and relentless precipitation.

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

While installing an air conditioner cover is an individual choice, there are two times of year that are good to use a cover for an extended period of time—fall and summer.  

That’s because yard rubbish 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 harder and may use more energy to cool your home.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from Farnell Heating & Air Conditioning Inc heating and cooling technicians can help. We’ll clean and lubricate your unit, and examine important components. This often allows us to spot trouble before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a couple ideas on picking the right cover. 

Avoid Full Covers

To keep air circulating, a protective air conditioner cover should only enclose the top of your unit and several inches on the side.

Full AC covers can trap moisture inside your unit, potentially rusting metal parts. It could also make your system 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 heavy snow is approaching. Snow and ice that build up inside your air conditioner can melt and refreeze, harming condenser coils and decreasing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your system if a severe storm is imminent in Mobile. Hail can critically damage your system’s exterior, impacting efficiency.
