When summer ends, so does the need to turn on the air conditioning. Unless performing regular maintenance, people rarely do anything to their AC during other seasons. In fact, many homeowners cover their units to protect them from damage. But is this really necessary?
SHOULD YOU COVER AN AC SYSTEM?
The only time experts recommend covering an AC is during the fall. The appliance can withstand snow and rain, but it’s not designed to keep out nuts, seeds, or leaves. If they get into the air conditioner, it becomes an ideal place for moisture that leads to corrosion. Debris can even clog any built-in moisture drainage components.
Therefore, cover the appliance in the fall, but only protect the top section. Covering the entire unit can be risky because it may trap moisture and result in rust.
Avoid any airflow-restrictive or plastic covers since they also promote moisture damage and rusting. Additionally, water-tight covers may invite animals to relocate to the air conditioner, which spells trouble on many levels.
If you have a window AC unit, it’s best to remove it when temperatures plummet. Consequently, there will be no draft around the system, and the unit’s lifespan will be prolonged. Keeping them in one place all year round can impede their operation and lead to more breakdowns, so it’s best to detach them during winter.
REASONS NOT TO COVER AN AC
Some people believe their AC needs to be covered during all seasons, not just the fall. But there’s no need to do that. Here’s why:
SHUTTING DOWN THE UNIT KEEPS DIRT AT BAY
When the air conditioner is on, it sucks in air and can attract dirt. Covering the unit prevents this scenario, but there’s a simpler solution—turning the system off. Once the unit is shut down, no dust or debris can enter it.
AC UNITS ARE DESIGNED TO ENDURE HARSH CONDITIONS
Another reason why people opt for covers is to shield their ACs from cold weather, snow, and ice. While this may help for extreme conditions and heavy snow build-up, it’s generally unnecessary. Modern appliances are built to withstand harsh winter conditions, eliminating the need for covers.
COVERS ATTRACT RODENTS
Contrary to popular belief, covers won’t keep rodents and other small animals from entering the AC. In lower temperatures, critters want to escape the cold, and a covered air conditioner is an ideal winter home. Also, various species have a way of accessing tiny spaces, meaning that covers aren’t much of an obstacle.
To sum up, AC covers are only recommended during the fall to protect the unit from debris and dirt. To get more advice on maintaining your system at this time of the year, consult a licensed HVAC professional.
