Do I Need to Cover My Air Conditioner?

With cold weather coming in Hamilton, you may be questioning 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 cause more problems, because they can trap water. Too much wetness inside your unit can cause internal components to rust or become 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 lengthy 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 longer and may use more power to cool your home.

Looking for other ways to make your air conditioner run efficiently? Annual AC maintenance from Carefree Heating and Cooling, LLC heating and cooling experts can help. We’ll clean and lubricate your equipment, and inspect important components. This often allows us to pinpoint trouble before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a few tips on picking the ideal cover. 

Avoid Full Covers

To keep air circulating, a protective air conditioner cover should only enclose the top of your unit 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 system an inviting 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 heavy snow is approaching. Snow and ice that accumulate inside your system can melt and refreeze, damaging condenser coils and decreasing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your air conditioner if a strong storm is approaching in Hamilton. Hail can critically damage your system’s coils, affecting efficiency.
