Fall is in the air in Cartersville, Georgia, which serves as a good reminder to keep these common HVAC myths in mind. Read on to learn the truth behind the industry’s most popular misconceptions.

Turn On a Fan to Reduce the Room’s Temperature

Contrary to popular belief, a fan doesn’t lower the temperature in your home. Regardless of whether you use a ceiling fan, a box fan or a standalone fan, all a fan does is create a wind-chill effect on the skin that makes a room feel cooler. Still not convinced? Check the thermostat when the fan is both on and off.

This isn’t to say that you shouldn’t use a fan to keep cool. You should, but turn it off when you leave the room to save energy.

Closing the Vents In an Unused Room Saves Energy

You would think that keeping the vents closed in an empty room would free up the energy to heat and cool the rest of the house. But this isn’t the case. In fact, closing the vents causes a pressure imbalance that puts an additional strain on the HVAC system.

You’re better off leaving the vents open or switching to a zoned system. A zoned system is designed to heat and cool individual areas of the home.

Your HVAC Technician Will Change the Air Filters

While your service technician can certainly change any dirty air filters during an annual maintenance visit, it’s your job to replace them every one to three months. Get in the habit of checking them monthly for any signs of dirt or clogs. If they look fine, check them again in a couple of weeks.

Once you know how often to change your filters, it becomes second nature. Simply keep a supply on hand, and replace them as needed.
