When Should You Use the ”Fan On” Setting on Your Thermostat?

Are you trying to keep your home comfortable but don’t know when to use the “fan on” setting on your thermostat? You’re not alone! Many homeowners struggle to understand when to use their thermostat fan on or auto settings and if using the “fan on” setting really makes a difference in your home’s heating and cooling. In this article, we’ll explain when you should use the “fan on” setting and how it can help you keep your home comfortable. Keep reading to learn more!

What is the “fan on” setting on your thermostat?

The “fan on” setting on your thermostat is a feature that allows the fan in your heating and cooling system to operate continuously, as opposed to just running when the unit is actively heating or cooling. This can be beneficial for many reasons, including improved air circulation throughout the home and better indoor air quality. However, this function uses more energy and shouldn’t be used all the time.

When you set your thermostat to the “fan on” setting, the blower motor will run constantly at whatever speed it has been set. This can help filter out dust and other allergens from circulating through the house while also providing more consistent airflow than if it was only operating when actively heating or cooling. So, since this thermostat setting uses more energy, when are you supposed to use it?

Use the fan setting when you’re dealing with allergies.

If you have allergies, you know how difficult it can be to find relief. Allergens like pollen, dust, and pet dander can trigger a myriad of uncomfortable symptoms, ranging from itchy eyes and sneezing to coughing and difficulty breathing. Fortunately, there are a few simple steps you can take to reduce the number of allergens in your home and promote better air quality. One of these steps is to use the “fan on” setting on your thermostat.

When you set your thermostat to the fan setting, it causes the system to pull air through the filter continuously, effectively cleaning the air if you’re suffering from poor indoor air quality. The fan setting also helps circulate the air in your home, which in turn helps reduce the number of allergens that accumulate in the air.

Cut the fan on your thermostat when outdoor temperatures are comfortable.

When outdoor temperatures are comfortable, there’s no need to have your thermostat set to a specific temperature. Instead, you should use the “fan on” setting to move air through the house and keep the air fresh and clean. This setting will not only keep your home smelling fresh but can also prevent your home from feeling stuffy and uncomfortable.

If your heating and cooling system is set to auto during periods of pleasant weather, you may go several days without your HVAC system cycling on. The result is a stuffy feeling and stale air settling throughout your home. By turning on your HVAC fan, it will help circulate the air throughout your home, ensuring all of your rooms have an even temperature and airflow. This setting also helps keep the air in your home fresh by preventing the stale air from settling in any one area of your home.

Use the on setting for your fan when you need to reduce humidity.

Reducing humidity in your home can be a challenge. Whether you live in an area with a humid climate or you’ve just experienced a particularly wet summer, you may be feeling the effects of excessive moisture in the air. Not only can humidity create an uncomfortable living environment but it can also lead to the growth of mold and mildew, which can have a negative impact on your health.

One of the simplest and most effective methods is to adjust your thermostat to the “fan on” setting. By running the fan continuously, you can keep the air in your home circulating, which helps reduce humidity. As the air circulates, it passes over the evaporator coils in your air conditioner, which removes moisture from the air. The result is a more comfortable home environment with lower levels of humidity.

Overall, using the ”fan on” setting on your thermostat can help to improve air quality and circulation throughout your home, keep your home smelling fresh, and help reduce humidity.
