Should I Cover My AC in the Winter?
While we'll go over some exceptions here in a moment, the general answer to this question is actually no. For most air conditioners, their construction is meant to allow them to withstand harsh weather conditions, including snow and ice. In many cases, covering them during the winter can actually do more harm than good.
How can this happen? There are a few ways:
- Trapping moisture inside: If you cover your AC unit, it can create a sealed environment that traps moisture inside. This can lead to mold and mildew growth, which can damage your air conditioner and affect the quality of the air it blows out when you use it in the future.
- Inviting pests: Covered AC units may also attract pests looking for a warm place to shelter during the cold winter months. These pests can cause damage to your unit or even make their way into your home through cracks or openings.
- Damage from heavy covers: Using a heavy cover on your AC unit can also result in physical damage, especially if there are strong winds or snowfall. The weight of the cover combined with external elements can cause dents, scratches, or other types of damage to your unit.
- Mold and mildew growth: When covering an AC unit for extended periods of time, moisture can become trapped inside the cover. This can lead to the growth of mold and mildew, which can not only damage your unit but also pose health risks to you and your family.
- Voiding warranty: Most manufacturers do not recommend covering AC units, as it may void their warranty. If any damages occur while using a cover, the manufacturer may refuse to provide repairs or replacements under warranty.
What To Do Instead
Instead of covering your AC during the winter, here are some other basic maintenance tips to follow:
- Regularly clean your AC unit: It is important to regularly clean your AC unit, especially before storing it for the winter. This will help prevent the buildup of debris and dust that can affect its performance.
- Trim surrounding vegetation: Make sure there are no tree branches or shrubs near your AC unit that could potentially damage it during strong winds or storms. Keep a clearance of at least two feet around the unit.
- Check and replace filters: Filters are an important part of your AC unit as they help keep the air clean. It is recommended to check and replace them every 1-3 months, depending on usage.
- Inspect for any leaks or damage: Before storing your AC unit away for the winter, make sure to inspect it for any leaks or damage. If you notice any issues, it is best to get them fixed before they worsen over time.
Exceptions
There are a few exceptions where it may be prudent to cover part or all of the outdoor AC unit during winter:
- Older unit: If your AC unit is older and prone to damage from extreme weather conditions, it may be a good idea to cover it with a tarp or protective covering.
- High wind areas: If you live in an area that experiences high winds during the winter, covering your outdoor AC unit can prevent any debris from causing damage.
- Heavy snowfall: In areas where heavy snowfall is common, covering the outdoor AC unit can prevent snow and ice buildup on the unit, which can lead to damage or malfunction.
