As the scorching summer heat starts to fade and the cooler temperatures of fall starts to settle in, residents of Central Point start preparing their homes and yards for the winter. For many, that leads to the question of whether they need to cover their outdoor air conditioner for the winter.

While it may seem like a smart idea, in reality there are a number of reasons why you shouldn’t cover your AC unit in the winter. Along with not being needed, covering your outdoor air conditioning equipment can sometimes cause problems.

Here, the professionals at Titan Heating & Air Conditioning share five reasons why covering your air conditioning equipment doesn’t need to be on your fall to-do list and what you should do instead.

1. Your AC can Handle Snow

Exterior AC units are designed to withstand harsh weather conditions like snow in the winter season. These machines are built with durable materials and hardware that can handle the outdoor elements without damage. The coils and fins of the unit are specially developed to resist corrosion, and the housing is crafted to protect the internal parts from moisture and debris.

2. Covered AC Systems may Encourage Mold Growth

One of the reasons you should avoid covering your air conditioner in the cold months is because doing so can trap moisture—which is definitely not what you want in your outdoor unit. That’s because sealing moisture inside the unit creates the perfect conditions for mold and mildew to spread.

Mold and mildew not only have an undesirable odor, but they can also present health risks, especially for individuals with respiratory issues or allergies. Plus, the excess moisture can corrode the internal components of the AC unit.

Rather than covering the unit, instead provide proper drainage and keep the area around the unit cleared of debris, allowing for efficient airflow and preventing moisture buildup.

3. A Covered Air Conditioner Can Attract Animals

Humans aren’t the only ones who make plans for winter. Animals that live around your home are also looking for a warm, cozy place to live for the winter months. For many animals, a covered air conditioner is the perfect winter dwelling.

Birds, mice, chipmunks and even rats frequently make nests inside covered air conditioners. Animals dwelling in a covered AC unit can cause numerous problems. Rodents can chew through wires, insulation and other connections, causing damage that may require expensive repairs. Debris animals bring into the AC to create a warm and comfortable home can obstruct airflow and ventilation, limiting the efficiency of the unit and potentially causing it to overheat. Moreover, animal excrement can result in unsanitary conditions and bad odors.

Leaving your air conditioner uncovered helps dissuade creatures, because an uncovered AC offers less shelter from the elements than a covered unit. That’s better for your cooling system—and leaves you with less mess to pick up and things to repair in the spring.

4. A Winter Cover for AC Units Restricts Airflow

Another reason not to cover your AC unit in the winter is because a cover limits airflow through the unit. Proper airflow is vital for the AC system because it facilitates heat exchange and allows the unit to cool effectively. When airflow is restricted, the system has to work harder to reach the desired temperature, resulting in additional energy consumption and strain on the components.

In addition, if you run your AC without noticing that the outdoor unit is covered or because you simply forgot, it could result in a range of problems. One issue is that the shortage of correct airflow could cause the compressor to overheat, leading to its failure or damage.  That’s why it is essential to ensure the outdoor unit has no barriers and is not covered to maintain maximum airflow.

5. AC Maintenance Works Better Than Covering Your Air Conditioner

The bottom line is, it’s a lot more effective to do a little maintenance for your cooling system than to cover your outside AC unit.

There are a number of key maintenance tasks you should prioritize to ensure optimal function and longevity of your AC unit. First, it’s a good idea to look at your outdoor AC unit regularly and get rid of any debris such as leaves, sticks and dirt to maintain proper airflow. Second, examine and clean the coils, fins and filters to make sure there isn’t any dirt and dust buildup that would hinder effective heat exchange or airflow.

Scheduled air conditioning maintenance not only enhances efficiency, but it also helps extend the unit’s life span, decreases energy consumption and avoids costly repairs. Rather than using a cover, investing time and effort into routine air conditioning maintenance is a proactive approach that can substantially benefit your entire HVAC system in the long run.
