The Perfect Thermostat Fan Setting

What setting should your thermostat fan be set on? You can set your fan to “on” or “auto” but what are the advantages of each setting?

When the thermostat fan is set to the “on” mode, it keeps the fan running all day, every day, regardless of the cooling or heating setting. The advantages are that it helps your system last longer due to less stopping and starting, it filters better air into your home and it distributes the air better resulting in increased comfort. The disadvantages include the expense associated with running the fan all day, it clogs your filters more quickly, and it can make the rooms feel “cooler” even if the temperature setting is higher.

When the thermostat fan is set to the “auto” mode, the fan will only turn on when it receives a signal. The advantages are you save money because the fan is running for shorter periods of time and your filters will last longer. The disadvantages are that the fans will wear out faster because of frequent stops and starts and the air will not be as evenly distributed.
