Spring is in full bloom! Flowers are blossoming, birds are singing, and the rain is pouring. While those April showers help bring May flowers, they can also take a toll on your HVAC system if you’re not prepared. Don’t let excess moisture and unpredictable weather put a damper on your home’s comfort.

One common misconception is that your AC unit needs a cover during colder or wet months. In reality, covering it can do more harm than good. A covered unit can become an inviting home for critters like rats, mice, and raccoons, which may nest inside and chew on vital wiring and components. To prevent unwanted damage, it’s best to leave your AC uncovered.

From water damage to humidity spikes, here’s how spring rain can impact your heating and cooling system, and what you can do to keep it running at its best.

Potential Water Damage to Outdoor Units

Your outdoor condenser unit is built to withstand the elements, but too much rain can still spell trouble. If water starts pooling around the base, you might be dealing with flooding, electrical issues, and even rusted parts. And let’s be honest, nobody wants a soggy, underperforming AC when the heat kicks in.

Here’s how to prevent water damage: 

• Check that your yard has proper drainage.
• Elevate the unit slightly if flooding is a recurring issue in your area.
• Keep gutters and downspouts clear so rainwater flows away from the unit.

Combat High Humidity 

Spring rain doesn’t just make the grass greener, it also cranks up the humidity. When there’s too much moisture in the air, your AC has to work overtime, making it less efficient and more prone to breakdowns. Plus, all that extra moisture can lead to mold growth inside your ducts. 

To keep your house dry, here are a few things to keep in mind: 

• Change your air filters regularly to keep airflow strong.
• Use a dehumidifier to keep indoor humidity at a comfortable level. Consider a programmable thermostat to help your system work smarter, not harder.

Watch out for Storm Debris

Heavy rainstorms bring more than just water, they also bring gusty winds that toss around leaves, dirt, and debris into your HVAC system. Clogged vents and dirty coils can lower efficiency, making your system work twice as hard. 

After a storm, take these steps to protect your unit:

• Regularly check and clear debris around your outdoor unit.
• Schedule seasonal maintenance to keep your system in top shape.
• Trim back trees and bushes to prevent stray branches from causing damage.

Spring’s Mood Swings = HVAC Overload

One day it’s 75 degrees and sunny, the next it’s chilly and pouring—welcome to spring! These dramatic temperature swings can make your HVAC system work harder than it needs to, leading to higher energy bills and potential system wear.

To keep your system running smoothly this season and next: 

• Use ceiling fans to help maintain even temperatures indoors.
• Avoid cranking the thermostat up and down (gradual adjustments are best).
• Upgrade to a smart thermostat that adapts to the weather and your lifestyle.
