Should You Cover Your AC for the Winter? Pros and Cons Explained 

Should I Cover Your AC for the Winter?
Posted on December 3, 2024
by Appleby Systems

As the temperatures drop, many homeowners wonder if covering their air conditioner during winter is necessary. While it seems like a practical step to protect your AC unit from harsh weather, improper covering can sometimes cause more harm than good. Let's explore the pros and cons of covering your AC and what you should do to keep it in excellent condition year-round. 

When Should You Cover Your AC Unit? 

In certain cases, covering your AC unit can be beneficial: 

  • Preventing Debris Buildup: A cover can protect your unit from falling leaves, branches, or other debris that may settle inside during the off-season. 
  • Guarding Against Ice Damage: If your area experiences significant ice storms, a properly fitted cover may reduce the risk of ice forming inside the unit, which can damage components. 

Tip: Use a cover designed specifically for AC units to ensure proper ventilation and avoid trapping moisture. 

The Risks of Covering Your AC 

Covering your air conditioner isn’t always the best idea. Here’s why: 

  • Moisture Buildup: A cover can trap moisture, leading to rust and corrosion of internal components. 
  • Pest Issues: Rodents and small animals may see the covered unit as a warm, cozy shelter, potentially causing damage by chewing wires or nesting inside. 
  • Lack of Airflow: Covers that completely block ventilation can create an environment where condensation builds up, leading to mold and mildew. 

How to Protect Your AC During Winter 

If you’re concerned about your AC, here’s what you can do instead of fully covering it: 

  1. Clear Debris: Regularly remove leaves, dirt, and other debris from around the unit. 
  1. Use a Top Cover: If you’re in an area prone to ice or heavy debris, use a cover that only shields the top of the unit, leaving the sides open for airflow. 
  1. Check the Unit Periodically: Inspect your AC unit for signs of damage or pest activity during the winter. 

Final Thoughts 

In most cases, fully covering your AC for the winter is unnecessary and may even cause harm. However, a partial cover or other protective measures can be helpful if done correctly. If you’re unsure how to winterize your air conditioner or need maintenance before the next cooling season, the experts at Appleby Systems are here to help.
