5 Reasons to Avoid Covering Your Air Conditioner in the Winter

As the scorching summer heat starts to fade and the refreshingly cool weather of fall starts to settle in, residents of Naples start preparing their homes and yards for the winter. 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 truth is there are several reasons why you shouldn’t cover your AC unit in the winter. Along with not being necessary, covering your outdoor air conditioning equipment can sometimes cause problems.

Here, the specialists at Speedy Air Conditioning share five reasons why covering your AC doesn’t need to be on your fall to-do list and what you should do instead.

1. Your AC Unit Isn’t Damaged by Snow

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

2. Covering Your Air Conditioner Can Cause Mold

One of the reasons you should not cover your outdoor air conditioning equipment in the winter is because doing so can trap moisture—which is definitely not what you want in your outdoor unit. That’s because trapping moisture inside the unit creates the perfect conditions for mold and mildew to thrive.

Mold and mildew not only have an unpleasant smell, but they can also present health risks, especially for individuals with respiratory issues or allergies. Additionally, the unwanted 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 clean 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 looking for a warm, cozy place to hide out for the wintry months. For many animals, a covered air conditioner is the perfect winter dwelling.

Birds, mice, chipmunks and even rats often make nests inside covered air conditioners. Animals dwelling in a covered air conditioning unit can cause several problems. Rats can chew through wires, insulation and other components, causing damage that may require costly repairs. Debris animals bring into the AC to make themselves a warm and comfortable bed can obstruct airflow and ventilation, decreasing the efficiency of the appliance and potentially causing it to overheat. Moreover, animal excrement can result in unsanitary conditions and potent odors.

Leaving your air conditioner uncovered helps deter animals, because an uncovered AC gives them less shelter from chilly temperatures than a covered unit. That’s better for your air conditioner—and leaves you with less mess to clean up and things to repair once the snow melts.

4. An AC Cover Restricts Airflow

Another reason it’s better that you don’t cover your air conditioning equipment in the winter is because a cover limits airflow through the unit. Adequate airflow is vital for the AC system because it facilitates heat exchange and enables the unit to cool effectively. When airflow is restricted, the system has to work harder to maintain the desired temperature, causing increased energy consumption and strain on the components.

In addition, if you turn on 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 absence of correct airflow could cause the compressor to overheat, resulting in its failure or damage. That’s why it is crucial to ensure the outdoor unit is always cleared of any barriers and is not covered to maintain optimal airflow.

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

The bottom line is, it’s a whole lot more effective to do a little maintenance for your air conditioner than to cover your exterior AC unit.

There are several key maintenance tasks you should prioritize to ensure optimal operation and longevity of your AC unit. First, it’s smart to examine your outdoor AC unit regularly and clear any debris such as leaves, twigs and dirt to allow 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 prevent efficient heat exchange or airflow.

Routine air conditioning maintenance not only improves efficiency, but it also helps extend the unit’s life span, decreases energy consumption and prevents costly repairs. Rather than using a cover, putting time and effort into routine air conditioning maintenance is a proactive plan of action that can substantially benefit your entire HVAC system in the long run.
