As the hot summer sun starts to fade and the relief of fall starts to settle in, residents of Central Point start preparing their homes and yards for the wintertime. For many, that leads to the question of whether they ought to cover their outdoor air conditioner for the winter.

While it may seem like a good idea, the fact is 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 conditioner 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 supposed to withstand harsh weather conditions like snow in the winter season. These systems 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 manufactured to protect the internal elements from moisture and debris.

2. Covering Your Air Conditioner Can Cause Mold

One of the reasons you shouldn’t cover your outdoor air conditioning equipment in the cold months is because doing so can trap moisture—which is not at all what you want in your outdoor unit. That’s because sealing moisture inside the unit generates the perfect conditions for mold and mildew to flourish.

Mold and mildew not only have a bad smell, but they can also pose health risks, especially for household residents with respiratory issues or allergies. Additionally, the trapped moisture can corrode the internal components of the AC unit.

As an alternative to covering the unit, instead make sure the unit has proper drainage and keep the area around the unit free of debris, allowing for efficient airflow and preventing moisture buildup.

3. A Covered Air Conditioner Can Attract Animals

Human beings aren’t the only ones who get ready for winter. Animals that live around your home are also searching for a warm, cozy place to hide out for the winter months. For many critters, a covered air conditioner is the perfect winter home.

Birds, mice, chipmunks and even rats often make winter dens inside covered air conditioners. Animals dwelling in a covered AC unit can cause numerous problems. Rats can chew through wires, insulation and other components, causing damage that may require costly repairs. Debris animals bring into the AC to create a warm and comfortable place to get out of the cold weather can obstruct airflow and ventilation, decreasing the efficiency of the AC and potentially causing it to overheat. Additionally, animal waste can result in unsanitary conditions and bad odors.

Leaving your air conditioner uncovered helps deter animals, because an uncovered AC provides less shelter from cold weather than a covered unit. That’s better for your air conditioner—and leaves you with less mess to throw away and things to repair when winter is over.

4. A Winter Cover for AC Units Restricts Airflow

Another reason you shouldn’t cover your air conditioner in the winter is because a cover limits airflow through the unit. Suitable airflow is essential for the AC system because it assists heat exchange and enables the unit to cool properly. When airflow is reduced, the system has to work harder to reach the desired temperature, causing greater energy consumption and strain on the components.

In addition, if you run your air conditioner without knowing 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 proper airflow could cause the compressor to overheat, leading to its failure or damage.  That’s why it is necessary to ensure the outdoor unit is always cleared of any barriers and is not covered to maintain maximum airflow.

5. AC Maintenance Is More Effective Than Covering Your Air Conditioner

The bottom line is, it’s lots more effective to do a little maintenance for your air conditioning unit than to cover your outside AC unit.

There are a number of key maintenance projects you should prioritize to ensure the best possible performance and longevity of your AC unit. First, it’s a good idea to inspect your outdoor AC unit regularly and remove any debris such as leaves, sticks and dirt to promote proper airflow. Second, check and clean the coils, fins and filters to make sure you don’t see any dirt and dust buildup that would hinder efficient heat exchange or airflow.

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