How to Protect Your Outdoor AC Unit During Severe Weather

Michigan weather can be unpredictable. From heavy thunderstorms and high winds to hail, snow, and ice, your outdoor AC unit faces year-round exposure to the elements. Taking steps to protect it not only prevents costly damage but also ensures your system runs efficiently when you need it most.

At Ehlers Heating and Cooling, we’ve seen how severe weather can take a toll on air conditioners. With a few preventative measures, you can reduce the risk of breakdowns and extend the life of your system.

Shield Your AC Unit from Storm Damage

Strong winds and flying debris are common during Michigan storms. Even small branches or loose yard items can dent the condenser fins or clog the unit with debris. To help prevent this:

• Remove loose objects (patio furniture, toys, garden tools) from around the unit when severe weather is expected.

• Trim trees and bushes near the condenser to reduce the chance of falling branches.

• Consider installing a protective fence or barrier that allows airflow but blocks debris.

Protect Against Flooding and Water Damage

Heavy rain and melting snow can lead to standing water around your unit, which may damage electrical components. To keep your AC safe:

• Make sure the unit is on a raised concrete pad or platform.

• Keep gutters and downspouts clear so water drains away from the system.

• If flooding is common in your area, talk to a technician about additional drainage solutions.

Prevent Hail and Ice Damage

Hailstorms and winter ice can dent the outdoor coil and restrict airflow. Simple steps like these can make a big difference:

• Use a specially designed AC condenser cover or cage during hail season.

• In winter, cover the unit with a breathable AC cover to keep snow and ice from building up inside.

• Never use plastic tarps, as they can trap moisture and cause rust.

Check for Damage After Severe Weather

Once a storm passes, take a quick look at your outdoor unit before turning it back on. Watch for:

• Visible dents or bent fins

• Flooding or standing water around the base

• Unusual noises when the system starts up

If you notice any issues, shut the system off and call Ehlers Heating and Cooling for an inspection. Running a damaged AC can make the problem worse and lead to costly repairs.

Schedule Preventative Maintenance

The best way to keep your AC unit safe is through regular maintenance. During a tune-up, our technicians check for wear, clear away debris, and make sure your system is ready to handle Michigan’s changing seasons. Preventative care helps your AC run more efficiently and last longer.
