In many parts of the world, the fall season is upon us. Children are back at school, leaves are changing colors, and temperatures are beginning to cool off. However, fall can also make climate control a challenge. There are a few signature characteristics of the autumn season that make it a great time to have an HVLS fan installed in your facility.
Cooler Air Means Less HVAC Use
Even though the air outside is cooler, because of machines, people and movement in a building, it’s likely that the building itself is still relatively warm. This means that instead of cranking up your HVAC, as you might need to do in spring or summer, you can simply circulate cool air from outside. Since HVLS fans are great at moving large volumes of air throughout a space, all you have to do is ensure that the fan has a source of cool air. Many facilities keep doors and windows open in the fall for exactly this reason.
HVLS Fans Help Control Pollen
Pollen can be found all year, but spring and fall are the two seasons in which pollen is typically at its worst. In the fall, the most prevalent kind of pollen is ragweed. Ragweed plants bloom and produce pollen between August and November, with levels usually peaking in mid-September. This type of pollen can cause uncomfortable allergic reactions like sneezing, coughing, and itchy eyes.
HVLS fans can help control pollen by improving airflow. Pollen and mold spores cause the most health problems when they are allowed to hang and stagnate in the air around people. With a quality HVLS fan, you’ll be able to increase ventilation and move pollen out of your building much more effectively, providing relief for people on your staff who suffer from seasonal allergies.
Reverse Operation Allows Flexibility for Cold and Warm Days
Since fall is often associated with cooler temperatures, you might wonder why a fan would be necessary for climate control. The top HVLS fans can operate in reverse, which means they can help spread warm air when it is cold outside and cool in the building. When a fan runs in reverse, it pushes warm air from the ceiling down to the floor level, helping warm up the building’s occupants.
But the fall season also often has warmer days, sometimes referred to as an “Indian summer.” On these days, it’s easy to use your fan regularly to help cool a space down. The best HVLS fans have remote controls with daisy-chained operation, so it’s a simple step to decide whether the fans run in the forward direction for cooling or in reverse for warming.
The Bottom Line on HVLS Fans in Fall
Fall is one of the most beautiful seasons of the year, but its weather patterns can be unpredictable. With the right HVLS fan, you’ll be able to keep your building at an acceptable temperature no matter what the fall weather brings, which is why HVLS fans are the perfect solution for climate control in autumn.
