If your home has ceiling fans, they can be a secret weapon to help cut your cooling costs. However, it’s important to know which way to set a ceiling fan for summer to make the most out of your savings. By having your fan spin counterclockwise, you can circulate cool air through the room, and the fan creates a chill effect. This allows you to lessen your reliance on your air conditioner, helping to cut down on energy use and lower costs. To elaborate, here’s how you can use your home’s ceiling fans to cut your AC bills.
Counterclockwise for Summer: How the Downdraft Cools You
Wondering which way a ceiling fan in summer should spin? The answer is counterclockwise. When you keep your ceiling fans rotating counterclockwise, they create a noticeable downdraft. That accomplishes two things. First, it supercharges your body’s natural cooling mechanism. When you get warm, you begin sweating. As your sweat evaporates, it carries heat away from your body. The extra airflow helps speed that process.
The second thing the downdraft does is push air down toward the floor. That naturally forces air near the floor upwards, equalizing the air temperature throughout the room. Since cold air naturally sinks, you never get the full comfort benefit of your AC unless you lie on the floor. Running your ceiling fan makes it so you don’t have to.
How to Tell Which Way Your Fan Is Spinning
Knowing which way your fan is spinning is the first step for setting your ceiling fan summer direction. If you picture the blades of a ceiling fan as the hands on a clock, their rotational direction is easy to discern. Blades that turn toward the right mimic the ordinary forward motion of a clock, so they’re said to move clockwise. Blades that turn to the left go in the opposite direction of a clock’s hands, so that’s counterclockwise.
How to Change Your Fan’s Direction
Most ceiling fans have a small black switch located somewhere on their housing. The switch on yours may have markings indicating its purpose, or it may not. Once you locate the switch, be sure to turn off your fan and let it stop turning before you change its position. Otherwise, you will stress the fan’s motor, shortening its lifespan. Newer ceiling fans with remote controls often have directional controls on the remote.
Summer vs. Winter Fan Settings
You can also use your ceiling fans to cut your home’s winter heating costs. To do so, switch your fans to clockwise rotation and run them at a lower speed. That prevents any cooling effects by eliminating downdrafts. However, it does draw cold air up from the floor while pushing warmer air down to where you’ll feel it.
Pairing Fans With AC to Raise the Thermostat & Save
It may shock you to learn how well pairing your ceiling fans with your AC can work. According to the Department of Energy, running your ceiling fans can let you raise your thermostat by four degrees comfortably. When you consider that every degree equates to about 3% of your cooling costs, that’s a massive help. It means your ceiling fans can cut your AC bills by up to 12%.
Ceiling fans can be especially helpful during periods of high humidity. Maintaining constant airflow prevents muggy air from making you feel warmer than the temperature suggests you should. It also helps you breathe a little easier, as high humidity is a major indoor air quality problem for Florida homes.
Do Fans Actually Cool a Room? (The Myth)
It’s important to know that, unlike your AC, your ceiling fans won’t change a room’s temperature on their own. They also won’t lower the humidity inside your home like your AC will. Instead, they help your body cool itself more effectively, which can help you tolerate warmer temperatures. They also help even out temperatures by reducing stratification in your home. Those two effects make you feel like your fan has lowered the temperature. However, ceiling fans alone are no substitute for AC on the hottest days and nights.
Still Uncomfortable? When It’s the AC, Not the Fan
If you’re already using your ceiling fans but it’s still too hot in your home, your AC may need attention. The first thing to check is your AC’s air filter. If it gets too dirty, it will restrict airflow and hamper your AC’s cooling capacity. Filter changes are a key part of HVAC maintenance and should happen approximately every 90 days. In the summer months, you may need to shorten your filter change interval because your AC spends more time running.
Your AC could also require repairs if it isn’t pushing out the cold air you expect. Blower motor problems and refrigerant leaks can keep your AC from working effectively. The latter problem is especially urgent, as it can lead to a frozen evaporator and compressor damage. If your AC isn’t working well and you’re not sure why, it’s a good idea to have it professionally inspected.
