Planning your plants.
A small fence or a hedge is a good way to hide an AC unit, but make sure the hedge doesn’t grow into the condenser. It is also wise to prevent a buildup of falling leaves, which can impede and damage the fan and compressor. When planting around your AC compressor choose trees that will not drop leaves during the winter, such as evergreen trees, oak trees, and beech trees. (Check with a local gardening center for advice.)
