When the summer heat kicks in, your air conditioner works overtime to keep your home cool. Some experts say that shading your outdoor unit can improve efficiency by as much as 10 percent. That might not sound like much, but over a season, it can add up to $100 to $250 in annual savings on your energy bills.
But is it worth the effort? The short answer: sometimes. When done correctly, shading your AC can help it run more efficiently and last longer. When done wrong, it can hurt performance. Let’s look at what makes the difference.
Does Shading Your AC Save Energy?
When direct sunlight hits your outdoor AC unit, it heats up the metal casing and the surrounding air. That extra heat makes the system work harder to release hot air from your home, which can raise energy use. Adding shade keeps the unit cooler, so it doesn’t strain as much, leading to lower energy bills and less wear on the system.
What’s the Best Way to Shade Your AC Unit?
The key is to create shade without blocking airflow. Your AC needs room to pull in and release air, so anything too close can trap heat and reduce efficiency. Aim to keep at least 2 to 3 feet of open space on all sides and 5 feet above the unit.
One of the best options is to plant trees or tall shrubs a few feet away to cast natural shade, while leaving plenty of breathing room. A small awning or lattice can also work if it doesn’t cover the top or restrict ventilation. Whatever you choose, focus on filtering direct sunlight instead of enclosing the unit.
What Are the Benefits of Shading Your AC?
Keeping your AC out of direct sunlight helps it cool the air faster and with less effort. That can cut down on how much electricity it uses during the hottest days of summer, which often means noticeable savings on your utility bill.
Shade also protects the compressor from constant heat exposure. Since the compressor is the heart of your AC and one of the most expensive parts to replace, reducing its workload can help the system last longer and avoid costly breakdowns.
Are There Any Issues with Shading Your AC?
Shading can help, but it’s easy to overdo it and hurt your AC instead. If plants, fences, or covers are too close, they can block the airflow your condenser needs to release heat. Without that airflow, the unit must work harder, which can raise energy use and cause overheating.
To avoid problems, keep at least 2 to 3 feet of clear space around the sides of the unit and about 5 feet above it. Skip dense bushes or low-hanging branches right next to the condenser and never cover the top; even a partial lid can trap hot air inside and damage the system.
