Do I Need to Cover My Air Conditioner?

With cold weather approaching in Mount Pleasant, 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 strong piece of equipment. It’s engineered to take on severe weather, including excessive temperatures and relentless precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Extra 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 seasons that are great for using a cover for a lengthy period of time—fall and summer.  

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

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Olde Towne Heating & Air heating and cooling experts can help. We’ll clean and lubricate your system, and take a close look at important components. This often allows us to identify trouble 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 several ideas on selecting the ideal cover. 

Avoid Full Covers

To keep air flowing, a protective air conditioner cover should only enclose the top of your equipment and a couple of inches on the side.

Full AC covers can trap moisture inside your system, potentially rusting metal parts. It could also make your air conditioner a cozy place for rodents, which could sever wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know heavy snow is coming. Snow and ice that build up inside your air conditioner can melt and refreeze, damaging condenser coils and lowering efficiency.

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