As the hot summer heat starts to fade and the cooler temperatures of fall starts to settle in, residents of Kankakee start preparing their homes and yards for the the upcoming cold weather. For many, that leads to the question of whether they ought to cover their exterior AC for the winter.
While it may seem like a good idea, the truth is there are many reasons why you shouldn’t cover your AC unit in the winter. In addition to not being needed, covering your outdoor air conditioning equipment can sometimes cause problems.
Here, the specialists at Home Furniture, Plumbing & Heating 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
Exterior AC units are built to withstand harsh weather conditions like snow in the winter. These units are built with sturdy materials and hardware that can handle the outdoor elements without damage. The coils and fins of the unit are constructed to resist corrosion, and the housing is crafted to protect the internal parts from moisture and debris.
2. Covering AC Systems can Encourage Mold
One of the reasons you should not cover your outdoor air conditioning equipment in the wintertime is because doing so can trap moisture—which is the opposite of 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 odor, but they can also pose health risks, especially for people with respiratory issues or allergies. Also, the excess moisture can corrode the internal components of the AC unit.
As an alternative to covering the unit, instead ensure 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
You and your family aren’t the only ones who prepare for winter. Animals that live around your home are also looking for a warm, cozy place to crash for the cold months. For many animals, a covered air conditioner is an ideal winter home.
Birds, mice, chipmunks and even rats frequently make homes inside covered air conditioners. Animals living in a covered air conditioner can cause numerous problems. Mice can chew through wires, insulation and other parts, causing damage that may require pricey repairs. Debris animals bring into the AC to make themselves a warm and comfortable nest can block airflow and ventilation, limiting 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 discourage animals, because an uncovered AC offers 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 when winter is over.
4. A Winter Cover for AC Units Restricts Airflow
Another reason you shouldn't cover your AC unit in the winter is because a cover restricts airflow through the unit. Proper airflow is crucial for the AC system because it assists heat exchange and permits the unit to cool properly. When airflow is constrained, the system has to work harder to reach the desired temperature, resulting in increased energy consumption and strain on the components.
In addition, if you run 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, causing its failure or damage. That’s why it is crucial to ensure the outdoor unit is free from 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 cooling system than to cover your exterior AC unit.
There are a number of key maintenance activities you should prioritize to ensure the best possible operation and longevity of your AC unit. First, it’s wise to inspect your outdoor AC unit regularly and remove any debris such as leaves, twigs and dirt to maintain proper airflow. Second, check and clean the coils, fins and filters to make sure there isn't any dirt and dust buildup that would impede effective heat exchange or airflow.
Regular air conditioning maintenance not only boosts 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 approach that can substantially benefit your entire HVAC system in the long run.
