Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Chatsworth, you may be thinking 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 created to resist bad weather, including extreme temperatures and heavy 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 become moldy.

While putting on an air conditioner cover is your own 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 rubbish during those seasons—grass clippings, twigs and leaves—can build up and lower your system’s airflow. Decreased 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 True Temp Heating & Air Inc heating and cooling professionals can help. We’ll clean and lubricate your system, and examine critical components. This often allows us to spot 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 a few tips on picking the ideal cover. 

Avoid Full Covers

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

Total AC covers can trap water inside your unit, potentially corroding metal pieces. It could also make your system a cozy place for rodents, which could chew 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 accumulate inside your air conditioner can melt and refreeze, harming condenser coils and lowering efficiency.
