HVAC Fan for Circulation of Air in the Home

Knowing whether running your HVAC fan often is beneficial begins with the consideration of several factors. For example, if you frequently experience extreme weather conditions or have a newer home with intake systems, running the fan often might not be necessary. Consider these factors to determine whether you should run your fan more or less.

1. Home:The way air circulates throughout your home may depend on its layoutor the type of home you have. Homes with multiple stories can experience more even temperatures with the HVAC fan running. A furnace fan pulls cold and warm air from their respective directions, combines them, and creates an uneven, comfortable temperature throughout the residence.
2. Occupants:Are you unable to keep windows open in your home because of someone’s healthor sensitivity? If the windows in your house are always closed, your property can benefit from using a fan during average temperatures and conditions.
3. HVAC system’s age:Newer HVAC systems often have better technology and advanced intake systems through the ductwork that mix inside and outside air. However, you need to heat or cool the air to make your home comfortable, so running the HVAC fan often with a newer system can create increased work. When it is too hot or cold, it can complicate things.
4. Outdoor temperatures:Milder outdoor temperatures are the best time to run your furnace fanoften. Since the temperature is not reaching one extreme or the other, your air conditioner or heater is not turning on to combat the conditions. Therefore, furnace fans are excellent for better airflow and temperature control.

Running the Fan with Moderate Temperatures

If you wonder, “How long should my HVAC fan run per hour?” then the answer is between ten to 20 minutes for two or three cycles. This works best when your home has amild outdoor temperature. When temperatures shift strongly towards 0 or 90 degrees (heating or cooling), you will need to run the fan longer.

Benefits of Running Your HVAC Fan

Your blower motor circulates air through the furnace and can provide uniform temperatures. Many people leave their HVAC fan on all day, while others opt for two to three cycles per hour, ranging from ten to 25 minutes, depending on how close to heating or cooling temperatures they are. Some advantages of keeping your fan on include the following:

• Since your furnace fan mixes all the air in your home, frequent operation can prevent prominent hot and cold spots.
• Air passing through your HVAC fan also runs through thefurnace filter. As a result, you’re receiving cleaner, filtered air throughout all areas of the home and experiencingsafer indoor air quality. If you have a UV light,too, the air will be even better.
• Some of the newer Energy Star furnaces are often equipped with constantly-running fan motors. The fan uses less energy than your heating or cooling systemsand ends up costing you less money to run this often. You’ll save money and have even temperatures.
• Running the HVAC fan can improve its lifespan because it is meant to run often. While some homeowners fear using it too much can cause heavy wear, it is actually best to turn on the motor and keep it on. However, before running the fan often, make sure your system has properly sealed ductworkand the installation is professional.
