As cold weather moves into Lake Zurich, IL, many homeowners begin getting their homes ready for winter. One question we hear a lot is: should you cover your air conditioner during the winter months? The answer isn’t always a simple yes or no—but knowing a few key facts can help you make the right choice for your home.
What Happens to Your AC in Winter?
Most outdoor AC units are built to handle cold weather. They’re made with durable materials that resist snow, ice, and wind. So in most cases, freezing temperatures alone won’t damage your system. However, other factors—like falling ice from the roof or piles of leaves—can create problems if the system isn’t protected.
When It Makes Sense to Use a Cover
- Your unit sits under trees or near areas where leaves and twigs fall
- You have roof runoff or icicles that drip onto the unit
- You want to keep out small animals or nesting pests during winter
If you do cover your unit, choose a breathable, waterproof cover. It should protect the top and allow air to flow through the sides. Never use plastic tarps or wrap the unit too tightly—this can trap moisture and lead to rust or mold.
When You Should Skip the Cover
- Your system is newer and designed to handle winter weather
- You don’t have overhanging trees or heavy debris nearby
- Your yard drains well and snow buildup isn’t a problem
In these cases, covering your AC could actually do more harm than good. Trapped moisture can lead to corrosion or attract pests. If your system is in a low-risk area, it’s often better to leave it uncovered and schedule regular maintenance instead.
