The argument of whether to cover an external air conditioning unit after summer never ends. Most people think the AC is designed as an outdoor structure and should not need any extra protection. To others, the AC should be protected to maintain its efficiency. The key reason for covering your unit is to prevent expensive repairs. So what dangers does your air conditioner face if left uncovered?

Hail and Icicles

During hailstorms, air conditioners are often forgotten. However, there are often storms just after winter that could damage your unit. The interior of the AC unit is as vulnerable as the exterior. Although dents will not affect how your AC runs, once the metal slat is damaged, the airflow will be impeded. Once inside the AC, hail may crack the bend the fans. Hail can also damage the condenser coil tubing and ductwork. To prevent such damages, cover your AC.

Seeds and Leaves

Air conditioners are not necessarily designed to keep out seeds and leaves. A small amount of leaves and seeds will not affect the unit. However, once debris builds up, problems can arise. Wet leaves and grass on the AC unit will decay to produce formic acid. Formic acid could eventually corrode the metal casing, which will allow the refrigerant to escape. Freon leaks are harmful to people and the environment. Furthermore, low refrigerant levels will lead to an overworked AC. Covering the top of the AC unit can prevent these damages.

Dirt and Dust

Dirt and dust result in dirty ducts and fans. If you suffer from asthma or allergies, dirty ducts could make your condition worse. Furthermore, your home will have poor air quality. Once it seeps into the AC, dirt acts like a sponge. It prevents the evaporation of water, resulting in the growth of mold and mildew. This reduces the efficiency of your unit. Dirty condenser coils require more energy to cool your home.
