As the hot summer sun starts to fade and the cooler temperatures of fall starts to settle in, residents of Winnipeg start preparing their homes and yards for the the upcoming cold weather. For many, that leads to the question of whether they should cover their exterior air conditioning unit 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 even cause problems.
Here, the specialists at Kirkfield 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
Exterior AC units are supposed to withstand harsh weather conditions like snow in the winter. These systems are built with durable materials and components 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 components 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 definitely not what you want in your outdoor unit. That’s because allowing moisture to collect inside the unit generates the perfect conditions for mold and mildew to thrive.
Mold and mildew not only have an unpleasant aroma, 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.
Instead of covering the unit, instead ensure proper drainage and keep the area around the unit cleared 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 get ready for winter. Animals that live around your home are also looking for a warm, cozy place to crash for the cold months. For many creatures, a covered air conditioner is an awesome winter dwelling.
Birds, mice, chipmunks and even rats commonly make winter dens inside covered air conditioners. Animals residing in a covered air conditioner can cause numerous problems. Rodents can chew through wires, insulation and other components, causing damage that may require expensive repairs. Debris animals bring into the AC to make themselves a warm and comfortable place to get out of the cold weather can impair airflow and ventilation, limiting the efficiency of the unit and potentially causing it to overheat. Moreover, animal waste can result in unsanitary conditions and foul odors.
Leaving your air conditioner uncovered helps discourage creatures, because an uncovered AC gives them less shelter from cold weather 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. Covering Your Air Conditioner Restricts Airflow
Another reason you shouldn't cover your air conditioner in the winter is because a cover blocks airflow through the unit. Proper airflow is vital for the AC system because it helps with heat exchange and allows the unit to cool efficiently. When airflow is reduced, the system has to work harder to achieve the desired temperature, causing greater energy consumption and strain on the components.
In addition, if you run 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, causing 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 maximum airflow.
5. AC Maintenance Works Better 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 outdoor AC unit.
There are several key maintenance projects you should prioritize to ensure optimal function and longevity of your AC unit. First, it’s wise to inspect your outdoor AC unit regularly and clear any debris such as leaves, small branches and dirt to maintain proper airflow. Second, check and clean the coils, fins and filters to make sure they are free from dirt and dust buildup that would prevent 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 avoids costly repairs. Rather than using a cover, putting time and effort into routine air conditioning maintenance is a proactive strategy that can significantly benefit your entire HVAC system in the long run.
