Air conditioners are specifically designed to withstand outdoor conditions throughout their lifetime. Rain, snow, and sun exposure are all factored into their construction. While a cover might seem like a way to keep your AC looking newer for longer, the reality is that covering your air conditioner can invite issues rather than solve them.
One major concern is rodents and pests. Covers create a warm, enclosed space, making your unit an attractive home for critters. Rodents can chew through wiring or cause other damage, leading to costly repairs.
Additionally, using non-breathable covers, such as tarps, can trap moisture. This creates a damp environment that leads to corrosion of internal components, ultimately destroying sensitive electronics. Even though your AC might look clean on the outside, the damage inside can significantly shorten its life.
When a Cover Might Be Acceptable
If you’re determined to cover your air conditioner, opt for a breathable cover. These covers allow airflow, reducing the risk of moisture buildup. Alternatively, placing a simple board on top of your unit can help keep leaves and other debris from falling in without trapping moisture.
However, even if leaves or debris accumulate in the bottom of your AC, it’s usually not a big problem. Unless the debris is severe—such as several inches deep—it won’t impact your unit’s performance significantly.
Spring AC Maintenance: Get Ahead of Potential Issues
When spring arrives, don’t wait for the first blazing 80-degree day to check your air conditioner. Instead, fire it up on a mild day, like the first 74-degree afternoon of the season. Run it for 15 minutes to ensure it’s blowing cold air. If it’s working properly, great! If not, you’ll have time to schedule repairs before the busy season when service appointments are harder to get.
Spring is also the perfect time to schedule an HVAC tune-up. Routine maintenance ensures your air conditioner is clean, efficient, and ready for summer. A professional tune-up can address any minor issues before they turn into major problems, saving you both time and money in the long run.
