Many homeowners think they should only use their furnaces in the winter to stave away the cold. However, running your furnace fan can make your home comfortable without using too much energy when the weather is milder. With this information, you might wonder, “How often should I run my furnace fan?”

When homeowners need expert furnace repair in Sudbury, Massachusetts, they call on Pro Comfort Control. As a top choice for HVAC services in the area, our company knows how frustrating it can be to have questions about the inner workings of a furnace and how to operate its fan. Thankfully, we’re here to answer your questions and help maximize your heating system’s output for optimal comfort.

Should You Run Your Furnace Fan Day in and Day Out?

Before answering questions about the frequency of operating a furnace fan, it helps to know how it redistributes air. You might notice the stack effect inside your house, which happens when cool air falls and warm air rises inside a closed space. That’s why a home’s upper levels tend to feel warmer than the rooms on the lowest floor.

When you run your furnace fan, the air inside your house blends, creating a more balanced temperature throughout the house. In the fall or spring, when temperatures are relatively mild, letting the furnace fan run for a few cycles per hour will make your home feel more comfortable without burning excess fuel to warm or chill the air.

Why Should You Operate Your Furnace Fan All the Time?

The answer to, “How often should I run my furnace fan?” is regularly, depending on your furnace. Doing so can yield many benefits. 

Reduced Energy Bills

Since running a furnace fan doesn’t require excessive energy in comparison to how much your HVAC system would consume to heat or cool your house, you can save money on electric bills while maximizing your comfort. Your home will maintain even temperatures, so the thermostat won’t constantly trigger the air conditioner or furnace to kick on. 

Improved Indoor Air

As the fan recirculates warm and cool air throughout the house, it will improve the indoor air quality. Every time the air circulates through the HVAC system, the air pushes through an HVAC filter that traps unwanted airborne particles like dust, dust mites, pet dander, pollen, and mold spores.

The air that comes through the filter is cleaner, with few allergens and contaminants. As a result, you’ll notice less dust settling on your surfaces. If anyone in your household suffers from asthma or allergies, they’ll also encounter fewer irritants due to the improved air quality. 

Another benefit of air continuously going through an air filter is odor reduction. The filter will also trap foul-smelling pollutants from mold, mildew, smoking, cleaning chemicals, and cooking, leaving your home smelling fresh. 

Lower Humidity

Humidity can be a year-long problem, but it’s a big issue when outdoor temperatures rise. Most people use their air conditioners to remove excess moisture from the air inside their homes.

However, you can save money and energy by running your furnace fan. Running the fan still forces air through the air conditioner’s evaporator coil, which is what draws heat and moisture from indoor air. 

Longer Furnace Lifespan

A common misconception about using furnace fans all the time is that it will cause the system to fail prematurely. Turning the blower motor on and off continuously is what puts the most undue stress on the system, so the furnace will experience less wear and tear if the fan is always on. 

When Is the Wrong Time To Run Your Furnace Fan Continuously?

Though it’s acceptable to run your furnace fan often, sometimes it’s the wrong thing to do. It’s best not to run the system if:

  • It’s the middle of summer and your ductwork is in your attic since the temperatures will be too high
  • Your ductwork is leaky
  • Your furnace is an old model
