How To Protect Your Outside AC Unit From Fallen Leaves

post img

When summer ends, autumn brings a timeless change to the trees as their leaves start to fall. As beautiful as they are, if you’re not careful, they can cause problems for your air conditioner. This is especially true if you live in a rural area like Livonia, MI.

Protecting your AC from falling leaves and other debris is critical to keep your AC in top condition. Leaves and debris can be incredibly destructive to outdoor AC units. Thankfully, you can take precautions to avoid AC repairs or AC replacement.

How Do Leaves Affect Your AC?

The first thing to understand is what happens when leaves enter your outdoor AC unit. Inside your AC is a compressor responsible for circulating refrigerant and releasing cool air. The compressor is a major component that can get damaged if leaves and other debris enter your system.

If the airflow in your compressor gets blocked, your AC will work harder and increase your electric bill. Trapped leaves and debris hold moisture that can cause rust and mold to critical components. This also leads to acidic gases that destroy the copper tubing inside your AC unit.

If you notice dirt, debris, weeds, or other residue inside your outdoor unit, call a professional HVAC company for cleaning and maintenance. This ensures your unit runs at its best.

How To Prepare Your Outdoor Air Conditioner for Winter

Before the winter sets in is a good time to practice preventative maintenance for your AC. You can take several steps to ensure your outdoor AC system is protected from leaves and debris.

Inspect for Debris

You should first inspect the area around your unit. This involves scanning the ground and walls or structures in the immediate vicinity. If you continuously notice dirt, leaves, or other debris like cottonwood at the bottom or inside your outdoor unit, consider raising your AC off the ground to prevent contaminants. 

Next, you’ll need to inspect the interior of your AC unit. This is the most vital part of maintaining the system. Most AC units have a removable side panel, but we recommend referring to your owner’s manual or calling a technician for help.

Clean the AC Unit

To clean the outside area of the AC unit, remove all leaves and debris within at least three feet. Check nearby areas for anything that might create more falling leaves or debris. Remove or relocate these things if possible.

You can spray the unit with a hose to wash away the debris. Don’t use high water pressure, or you might damage the AC fins.

Remove any foreign objects from the interior of the AC unit, and be careful not to damage the unit with excessive force. If anything is stuck, call for professional help right away.

Protect Your Outdoor AC Unit With a Cover

Covering the air conditioner for the winter will prevent rain, snow, fallen leaves, and other winter hazards from damaging the unit. However, it’s important to choose the right material.

When deciding on the best AC cover, don’t use plastic or vinyl, since they aren’t breathable. These materials allow moisture buildup and lead to rust or mold. The best option is to use a breathable material such as canvas to keep your AC protected without risking rust or mold.

Use a Leaf Guard Cover Year-Round

If you notice plenty of leaves and debris entering your AC unit, you should install a high-quality leaf guard cover. This mesh barrier will help keep out leaves and debris without sacrificing airflow all year.

A leaf guard will make inspecting and cleaning your unit easier, especially in the winter. It’s a worthwhile investment.

Schedule Routine Maintenance

Scheduling professional preventative maintenance before winter will ensure your AC system is ready for the next summer. AC maintenance will extend the life of your system, reduce energy bills, and prevent future costly repairs.
