Should I Cover My AC Unit in the Colder Months?

It’s a valid question to ask if you should be covering your AC unit during the winter months. After all, outdoor units are often exposed to harsh weather conditions, such as heavy snow and ice. On one hand, a cover can help protect the unit from these conditions, minimizing the risk of damage. On the other hand, a cover may trap moisture, leading to corrosion or a buildup of mold. It’s important to weigh these pros and cons and consider specifics such as climate, type of AC unit, and manufacturer recommendations. Remember, taking appropriate preventative measures can significantly prolong the lifespan of your AC unit and ensure its optimal performance. Van Drunen Heating & Air Conditioning is here to provide you with expert advice and guidance on all things related to HVAC. 

The Purpose of an AC Unit Cover

Firstly, it’s essential to understand the purpose of an AC unit cover. The primary function of these covers is to protect your AC unit from various weather conditions, including snow, rain, and extreme heat. AC units are typically constructed with a sturdy metal covering designed to resist these harsh elements. Therefore, the need for additional cover may not be as crucial as some homeowners believe.

Potential Drawbacks of Covering Your AC Unit

While it may seem logical to add an additional layer of protection to your AC unit during the winter months, doing so can have some potential drawbacks. For instance, a cover can trap moisture inside the unit, leading to mold and rust. This trapped moisture can significantly shorten the lifespan of your AC unit and lead to expensive repairs. Furthermore, covers could potentially attract small animals seeking warmth and shelter, which can lead to further damage.

Benefits of Leaving Your AC Unit Uncovered

On the other hand, leaving your AC unit uncovered during the colder months has several benefits. Uncovered units allow for natural airflow and ventilation, which helps prevent moisture buildup. Additionally, without a cover, there’s less chance of damage from falling icicles, as they’re more likely to bounce off an uncovered, hard surface than puncture a soft cover.

Preparing Your AC Unit for the Colder Months

Regardless of whether you choose to cover your AC unit or not, certain steps should be taken to prepare your unit for the colder months. These include clearing any debris from the unit, removing icicles if possible, and considering the use of mesh coverings to protect against leaves and other fall debris.
