Your central AC system is quite an investment. In fact, it’s probably one of the most expensive mechanical systems in your home. So it stands to reason that you want it to last as long as possible. In addition to regular filter changes and routine preventive maintenance, some homeowners choose to cover their condenser (outdoor unit) with an AC cover. But can doing so cause more harm than good? Perhaps.
Experts generally recommend against using an AC cover for several reasons. Read on as we discuss why covering your outdoor unit might nit be such a great idea.
Traps Moisture
Central air conditioners are designed to withstand exposure to the elements, including rain and snow. When you cover the unit, however, you may inadvertently trap moisture inside, especially if the cover is not breathable. This can lead to a number of issues, including rust, corrosion, and mold growth.
Creates a Perfect Environment for Pests
Covering your AC unit can create a sheltered space that is attractive to rodents, insects, and other pests. The warmth and protection offered by the cover can make it an ideal place for critters to nest during the winter months. Squirrels, mice, and other animals may crawl into the unit, chewing on wires or creating blockages in the system. This can cause significant damage to your AC system, which may go unnoticed until you attempt to start the system in the spring.
Prevents Airflow
Air conditioners are designed to breathe. Proper airflow is essential for the functioning of the system, and covering the unit restricts this airflow. Even if your cover has some ventilation, it likely doesn’t provide enough for the unit to stay dry and avoid internal moisture buildup. Without adequate ventilation, the unit can become a breeding ground for mold, mildew, and rust.
Unit is Designed for the Outdoors
Air conditioners are built to withstand exposure to outdoor weather conditions. The components of your AC unit, including the compressor, coils, and condenser, are made to endure rain, snow, and cold temperatures. They are specifically designed for outdoor use, meaning that adding an unnecessary cover can interfere with the natural protection the unit already has.
Can Block Drainage
AC units are designed with drainage systems to allow water and condensation to escape. A cover can obstruct this drainage, leading to water accumulation within the unit. Standing water inside the AC can freeze during the winter months, leading to potential damage to the internal components. Frozen water can crack or damage coils, pipes, and other vital parts of the unit, resulting in expensive repairs when you start using it again.
While the idea of covering your outdoor AC unit might seem like a good way to protect it from the elements, it’s often more harmful than beneficial. Instead of using a cover, focus on maintaining your AC unit properly by keeping it maintained. And should issues arise with any of your home comfort systems, contact Eagle Service Company.
