@user1267682121381: Your AC is working overtime and your energy bill shows it Sun heats it up. Dirt slows it down. This fixes both. I added a breathable cover to keep it clean (especially important in the fall/winter) and an AC fence to block direct sun Cleaner + cooler AC = better airflow and lower energy use.#ExternalAirConditioningCover #DealsforYouDays #SummerWins
