Do You Always Need to Be Running Your Furnace Blower Fan?

Homeowners come up with all sorts of questions to ask that will allow them to control their home’s energy costs yet remain as comfortable as possible throughout the day and night. One such inquiry that comes up quite often is whether or not the furnace blower fan should be running continuously. Let’s briefly discuss how this device works and the benefits you’ll receive from running it day in and day out.

How a Furnace Blower Fan Works

While the furnace blower fan is an essential part of an HVAC system, it’s not an especially complicated one. Its function is to move heat throughout your home as needed. But even though people think of it as primarily used for heating, it can also be used during the summer to assist with cooling — to a certain degree. This is why it’s indispensable no matter what time of year it is.

Benefits of Always Running the Fan

While you may feel apprehensive about running any piece of equipment on a continuous basis, many homeowners have found much success in doing so with their furnace fan. These are the primary benefits you’ll receive:

  • Increases Circulation. In a two-level home, the furnace fan will pull cool air from below and warm air from above, then redistribute the mixture at a more even temperature.
  • Reduces Humidity. The furnace blower fan pulls moisture from the air, thereby lowering humidity and helping sensitive household members to breathe easier.
  • Lowers Energy Bills. These fans cost very little to run, and since it can give you more even temperatures, you won’t need to run your air conditioner as often.
  • Extends Unit’s Life Span. Starting and stopping is what puts stress on a furnace’s motor, so running the fan continuously will actually help prolong the system’s life span.
  • Improves Air Quality. Running your furnace fan all the time means air will be continuously cycled through the filter and/or UV lights and stay much cleaner.
