With cold weather approaching in Elk River, 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 tough piece of equipment. It’s engineered to resist severe weather, including extreme temperatures and heavy precipitation.

Sometimes covers do more harm than good because they can trap moisture. Additional wetness inside your system can cause internal pieces to rust or become moldy.

While using an air conditioner cover is an individual choice, there are two periods that are ideal for using a cover for an extended period of time—fall and summer.

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can pile up and obstruct your system’s airflow. Reduced airflow means your air conditioning unit works harder and may use more energy to cool your home.

Seeking other ways to make your air conditioner run efficiently? Routine AC maintenance from Home Comfort Heating & Air heating and cooling experts can help. We’ll clean and lubricate your system, and take a close look at essential components. This often allows us to identify problems before they begin.

Choosing the Right 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 moving, a protective air conditioner cover should only surround 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 components. It could also make your AC a welcoming place for rodents, which could eat through wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers impede air, which could cause condensation to build up inside your system. The best type of fabric is one that’s breathable, like canvas or mesh.

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 collect inside your air conditioner can melt and refreeze, damaging condenser coils and lowering efficiency.

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