With cold weather on the horizon in Mobile, you may be thinking when you should cover your outdoor air conditioner. Of if you should even cover it at all.

Your AC unit is a sturdy piece of equipment. It’s engineered to resist bad weather, including intense temperatures and torrential precipitation.

Sometimes covers cause more problems because they can trap condensation. Additional 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 seasons 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 build up and block your system’s airflow. Decreased airflow means your air conditioning unit works longer and may use more energy to cool your house.

Looking for other ways to make your air conditioner run efficiently? Routine AC maintenance from Farnell Heating & Air Conditioning Inc heating and cooling professionals can help. We’ll clean and lubricate your system, and take a close look at important pieces. This often allows us to identify issues 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 suggestions on picking the ideal cover.

Avoid Full Covers

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

Complete AC covers can trap condensation inside your unit, potentially rusting metal pieces. It could also make your air conditioner a welcoming home 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 a blizzard is coming. Snow and ice that accumulate inside your AC can melt and refreeze, harming condenser coils and lowering efficiency.

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