When it comes to your HVAC system, you want to make sure you are using best practices to get the most out of your commercial heating and cooling equipment. One aspect that is often overlooked by companies is selecting the best setting for the HVAC fan. The first choice sets the fan to AUTO, meaning the fan only runs when the air conditioning or heating system is running. The second choice sets the fan to ON, which means the fan runs all of the time.
At Airlogix, we strive to make your life easier and more comfortable with smart solutions for your HVAC system. However, if you decide to operate the fan, you should know that pros and cons apply to each setting.
The Intermittent Fan Choice
Not running the fan all of the time saves you energy costs. If you work in a large building, this could significantly decrease monthly electrical bills. Intermittent fan use will also decrease the strain on your furnace filters, which are needed to keep the indoor air of high quality. You will be able to go longer without switching out filters, also saving you some money.
You also might notice some improved performance issues with keeping the fan off at times. Without the fan running, the air temperature is likely to stay just a little bit steadier, leading to improved comfort. You also could see improved humidity control with this option.
The Constant Fan Choice
Having the fan on all the time can improve air quality and eliminate stuffy air and some odors. This setting also reduces stress on the fan motor because it is easier for the system to stay on than to switch on and off. This could pay off in lower maintenance and greater longevity for the fan.
