As the scorching summer sun starts to fade and the refreshingly cool weather of fall starts to settle in, residents of Norco and St. Charles Parish start preparing their homes and yards for the winter. For many, that leads to the question of whether they need to cover their outdoor AC for the winter.
While it may seem like a great idea, the reality is there are several reasons why you shouldn’t cover your AC unit in the winter. Along with not being something you need to do, covering your outdoor air conditioning equipment can sometimes cause problems.
Here, the professionals at Mayeuxs AC & Heating 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
Outdoor AC units are designed to withstand harsh weather conditions like snow in the winter season. These machines are built with sturdy materials and parts that can handle the outdoor elements without damage. The coils and fins of the unit are engineered to resist corrosion, and the housing is crafted to protect the internal parts from moisture and debris.
2. Covering Your Air Conditioner Can Cause Mold
One of the reasons you should avoid covering your air conditioner in the cold months 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 thrive.
Mold and mildew not only have a bad smell, but they can also create health risks, especially for people with respiratory issues or allergies. Plus, the trapped 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 clear of debris, allowing for efficient airflow and preventing moisture buildup.
3. A Covered Air Conditioner Can Host 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 live for the wintry months. For many creatures, a covered air conditioner is an awesome winter dwelling.
Birds, mice, chipmunks and even rats commonly make homes inside covered air conditioners. Animals living in a covered air conditioner can cause numerous problems. Rodents can chew through wires, insulation and other parts, 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 appliance and potentially causing it to overheat. Moreover, animal droppings can result in unsanitary conditions and potent odors.
Leaving your air conditioner uncovered helps deter 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 clean up and things to repair in the spring.
4. Covering Your Air Conditioner Restricts Airflow
Another reason you shouldn't cover your air conditioning equipment in the winter is because a cover limits airflow through the unit. Suitable airflow is vital for the AC system because it facilitates heat exchange and allows the unit to cool efficiently. When airflow is restricted, the system has to work harder to reach the desired temperature, leading to increased energy consumption and strain on the components.
In addition, if you turn on your air conditioning without noticing that the exterior 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 vital to ensure the outdoor unit is free from obstructions and is not covered to maintain optimal airflow.
5. AC Maintenance Works Better Than Covering Your Air Conditioner
The bottom line is, it's much more effective to do a little maintenance for your air conditioner than to cover your outdoor AC unit.
There are a number of key maintenance tasks you should prioritize to ensure optimal operation and longevity of your AC unit. First, it’s wise to inspect your outdoor AC unit regularly and get rid of any debris such as leaves, sticks and dirt to maintain 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 successful heat exchange or airflow.
Scheduled air conditioning maintenance not only boosts efficiency, but it also helps extend the unit's life span, reduces 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.
