Changing your Commercial and HVLS Ceiling Fan Direction for Summer

March 16, 2020 by Patrick Munar

It is time for a season change again. As we move out of winter, and into spring and summer we start to think about how to cool our area more efficiently. While most ceiling fans can be used year around, it is easy to forget to change the ceiling fan direction from summer to winter, and winter to summer.

Typically, when you run your industrial ceiling fan the right way, you can effectively save on heating and cooling costs. In the summer, you may recoup about 30 percent of energy bills by raising the air conditioning unit or HVAC thermostat by four degrees and save 15 percent in the winter.

Who benefits from changing the ceiling fan direction?

We know that warm air rises, and cold air is heavier than warm air. For many service industries these fluctuations in the air temperature can mean the world of difference to not only employees but the product itself. Keep in mind, for there can be up to one-degree warmer temperature for every foot of height of the ceiling during the summer and winter months. Plant equipment and the sun rays beating on the roof can affect the overall temperature inside a facility between the floor and the ceiling.

Industrial ceiling fans are great for manufacturing plants, warehouses, greenhouses, and agricultural facilities. However, if the ceiling fan is set to spin clockwise, it pushes the warmer air from the ceiling down onto the employees making them feel hotter than need be. In the summer the ceiling fan needs to be set counterclockwise to circulate the cooler air that is near the floor area around the employees and the products inside, the air movement gives off a cool breeze as the air passes over.

How check the direction your ceiling fan is set to?

If you have a regular industrial or commercial ceiling fan that has a traditional switch, it is often hard to determine which setting is correct for summer. One tip is to stand under the ceiling fan while the blades rotate. As you look at the blades while turning, they should move counterclockwise, from the top left down to the right and you should feel air moving over you. If you do not feel the air moving, more than likely your setting is still set for winter at clockwise. Find the motor housing and flip the switch the opposite of what it is set to. This will start the blades spinning in the opposite direction.

Many HVLS ceiling fans have a remote that you can make the switch in the direction from summer to winter months easily. To fully benefit from changing the direction on your ceiling fan, the position of the ceiling fan is just as important. They should be installed between seven and nine feet from the ceiling to the floor. However, if you have vaulted ceilings, you should make sure your ceiling fan has a blade circumference that fits your area. Using too small of a fan, may actually increase your energy costs as it will work overtime to try and cool too big of space. Remember, residential ceiling fans are not optimal for large commercial spaces and they will need the speed and versatility to do their job sufficiently.

Industrial Ceiling Fan  – Best for maximum area coverage with a heavy-duty motor. Great for summer cooling and winter heat de-stratification. Great for warehouses and storages, manufacturing facilities and any place that large areas need more air flow and circulation.

Commercial Ceiling Fans  – Great for offices, classrooms, stores and restaurants, as they are heavy duty and can provide maximum heating and cooling supplementation. A good fit for ceilings 15 foot and below.

Agricultural Fans  – For animal facilities such as dairy and horse barns, poultry buildings and greenhouses, these ceiling fans can provide continuous use through the summer and winter as they are designed for harsh environments with sealed motors.

Make sure your employees, your customers, plants and livestock stay cool in the summer by changing the ceiling fan direction for the summer at the proper time. You will notice the energy savings in your heating and air bills.
