As the sweltering summer sun starts to fade and the relief of fall starts to settle in, residents of Odessa start preparing their homes and yards for the wintertime. For many, that leads to the question of whether they should cover their outdoor air conditioning unit for the winter.
While it may seem like a great idea, the fact is there are many 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 experts at Redhawk 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 Unit Isn’t Damaged by Snow
Outside AC units are designed to withstand harsh weather conditions like snow in the winter. These units are built with sturdy 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 manufactured to protect the internal elements from moisture and debris.
2. Covering Your Air Conditioner Can Cause Mold
One of the reasons you should avoid covering your AC unit in the winter is because doing so can trap moisture—which is not at all what you want in your outdoor unit. That’s because trapping moisture inside the unit produces the perfect conditions for mold and mildew to thrive.
Mold and mildew not only have an unpleasant aroma, but they can also pose health risks, especially for household residents with respiratory issues or allergies. Plus, the unwanted moisture can corrode the internal components of the AC unit.
Instead of covering the unit, instead provide 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
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 wintry months. For many animals, a covered air conditioner is the perfect winter refuge.
Birds, mice, chipmunks and even rats commonly make winter dens inside covered air conditioners. Animals residing in a covered AC unit can cause numerous problems. Rodents can chew through wires, insulation and other components, causing damage that may require pricey repairs. Debris animals bring into the AC to create a warm and comfortable place to get out of the cold weather can block airflow and ventilation, decreasing the efficiency of the AC and potentially causing it to overheat. In addition, animal waste can result in unsanitary conditions and bad odors.
Leaving your air conditioner uncovered helps discourage wildlife, because an uncovered AC provides less shelter from chilly temperatures than a covered unit. That’s better for your air conditioner—and leaves you with less mess to throw away and things to repair once the snow melts.
4. Covering Your Air Conditioner Restricts Airflow
Another reason it's better that you don't cover your AC unit in the winter is because a cover blocks airflow through the unit. Adequate airflow is crucial for the AC system because it assists heat exchange and allows the unit to cool effectively. When airflow is severely limited, the system has to work harder to maintain the desired temperature, leading to additional energy consumption and strain on the components.
In addition, if you turn on your air conditioning without realizing 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 proper airflow could cause the compressor to overheat, leading to its failure or damage. That’s why it is vital to ensure the outdoor unit is free from barriers and is not covered to maintain the best possible airflow.
5. AC Maintenance Works Better Than Covering Your Air Conditioner
The bottom line is, it's lots more effective to do a little maintenance for your cooling system than to cover your outdoor AC unit.
There are a number of key maintenance tasks you should prioritize to ensure the best possible function and longevity of your AC unit. First, it’s wise to look at your outdoor AC unit regularly and remove any debris such as leaves, small branches and dirt to allow proper airflow. Second, check and clean the coils, fins and filters to make sure there isn't any dirt and dust buildup that would prevent successful 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 protects against costly repairs. Rather than using a cover, committing time and effort into routine air conditioning maintenance is a proactive strategy that can substantially benefit your entire HVAC system in the long run.
