Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Reinholds, you may be questioning when you should cover your outdoor air conditioner. Of if you should even cover it at all.

Your AC unit is a strong piece of equipment. It’s created to withstand severe weather, including excessive temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap moisture. Extra wetness inside your unit can cause internal parts to rust or get moldy.

While installing an air conditioner cover is a personal choice, there are two periods 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 pile up and lower your system’s airflow. Decreased airflow means your air conditioning unit works longer and may use more energy to cool your home.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from County Line Mechanical LLC heating and cooling experts can help. We’ll clean and lubricate your unit, and take a close look at essential parts. 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 choosing the best cover. 

Avoid Full Covers

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

Full AC covers can trap condensation inside your system, potentially eating away at metal pieces. It could also make your air conditioner a cozy home for rodents, which could eat through wires.

Plastic or vinyl covers stop air, which could cause condensation to build up inside your unit. The best type of fabric is one that allows airflow, like canvas or mesh.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a snowstorm is coming. 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 system if a strong storm is approaching in Reinholds. Hail can critically damage your system’s coils, affecting efficiency.
