How To Use A Flower Bed To Hide An Outdoor AC Unit

Air conditioning is something many people would struggle to live without. As well as keeping you cool, it helps dehumidify the air inside your home, which creates a more comfortable environment. However, whether you use central air or a mini-split, there's a sizable condenser that sits outside. Even if it's hidden around the back of your house, it's not the nicest thing to look at in the yard. There are a couple of ways to conceal the condenser, though. For example, those who are handy with tools might want to cover it with a DIY wood pallet project.

Another, arguably more attractive, idea is to use a flower bed to hide an outdoor AC unit. You can create one by digging directly into the earth and growing tall plants that will provide an effective screen, or you can use planters with trellises up the backs, allowing you to mix low-growing plants with climbers for a more diverse feel. Before you reach for your trowel, though, there are some important things to consider. Making the wrong choices could impact the lifespan of your AC and the health of the plants you grow. So let's dive into the details.

There are several mistakes to avoid when landscaping around an AC unit, but the most important thing is never to restrict the air flow of the unit. Doing so not only reduces the unit's efficiency, but it can also cause overheating that will shorten its working life. Each manufacturer has its own recommendations, and it's something you should check, but a general rule is an absolute minimum of 2 feet of clearance all around. Also, bear in mind that the unit might need maintenance or repair, so there should be room for someone to work. If you're using planters, you might want to add wheels so they can be moved out of the way easily.

Choice of planting is also important. Avoid plants that drop lots of small leaves or petals because these can get blown into the machine and cause damage. Be careful with flowering plants that attract bees and wasps as AC condensers can be a cozy place for them to build nests. The condenser unit often blows out hot air, so it's a good idea to choose plants that can handle that environment.

It sounds like there are lots of restrictions, but there are still hundreds, if not thousands, of suitable plants. Bamboos make a terrific screen. Marigolds, geraniums, and a number of tall flowering herbs repel insects while blocking the AC unit. There are numerous drought-tolerant vines and climbers that can handle the environment. Alternatively, evergreens (including many flowering shrubs) can be a great way to hide the outdoor AC unit all year round.
