Now, when it comes to winterizing HVAC units, many people ask the same question: “should I cover my air conditioner for winter?” If you are too, then let this article help you out.
The winter season can cause several problems for your home. When the temperature starts to drip, you have to pay close attention to your plumbing pipes. You have to clear the snow from your driveway and pathway. You also have to ensure that you and your family have sufficient heating. On top of that, you need to protect some of the fixtures, appliances, or systems that won’t be used during the cold weather – and this includes your air conditioner.
As soon as the weather turns cold, your central air conditioner would be on standby. But if you want it to work efficiently the next time, you will have to make sure that it is ready for the winter. This means cutting the power supply and removing leaves and twigs.

Should I Cover My Air Conditioner for Winter? – The Answer Provided By Homeowners
For most homeowners, covering their air conditioners provides them with peace of mind, especially when there’s a major storm coming. Furthermore, AC covers are easily accessible and inexpensive. Thus, making them a reasonable option.
That said, we understand that it can be difficult to make up your mind, especially since air conditioners are a major appliance. Any damages caused with or without a cover can be a major problem. So to help you weigh your options, here’s a list of the advantages and disadvantages of using a cover.
Disadvantages of Covering Your Air Conditioner in Winter
- Can trap moisture inside, causing rust and corrosion to your system. This trapped moisture can also freeze on the coils, which eventually causes damage to your unit. Additionally, this can encourage mold and mildew to grow.
- When AC’s are covered, this creates a warm, dry, and relatively safe environment, which is irresistible to rodents that are looking for a home during winter. Once settled in, they can chew up your wires for their nests.
Advantages of Covering Your Air Conditioner in Winter
- Protects your unit from falling ice, which can damage the exterior and coil fins of your unit.
- Help keep the coils cleaner, which makes them work more efficiently later on.
- Prevents water from staying on the coils, which usually freezes in cold temperatures.
- Prevents leaves and heavy debris from getting caught in your condenser coil.
When to Cover Your Air Conditioner
Going back to the question: “should I cover my air conditioner in winter?” The answer is yes. When you cover your air conditioner during the winter, you can safeguard it and make it last longer. However, doing so isn’t always necessary.
Generally, if you live in an area with high humidity or experience a lot of precipitation, don’t cover your air conditioner. Under such conditions, moisture can be trapped under the cover, causing more damage to your unit.
So when is it necessary? If there are advisories on major storms and harsh weather conditions, you can take extra precautions by covering your air conditioner. This can include hail storms, wind storms, and blizzards. Then once the weather has passed, you can remove the cover. Doing this allows you to enjoy the benefits of using a cover without causing damages to your AC.
Ultimately, the decision to use a cover depends on you and whether you think the advantages outweigh the disadvantages or vice versa. But if you do decide to cover your unit, just make sure that you do it right and that you use the right item. Here are some cover ideas that you can use to get the job done and prevent damages to your system.
