Your thermostat's fan setting manages the blower for your HVAC system. The blower assists in moving hot or cold air about your house until the thermostat's set temperature is attained. Your thermostat has two options for controlling the fan: auto and on.

Advantages of using the AUTO setting on your thermostat's fan

  1. The option that uses the least energy is to leave your fan on AUTO. The fan doesn't operate all the time; it just runs when the system is turned on. This can end up saving you BIG on utility costs.
  2. Better dehumidification and moisture control (especially in summer months)
  3. Reduced overall wear and tear on your entire AC system, potentially extending its lifespan

Advantages of using the ON setting on your thermostat's fan

  1. By allowing the fan to run uninterrupted, you’ll achieve a more even distribution of warm or cool air circulating through your home. This will help reduce hot or cold spots within your home.
  2. Less frequent starts and stops might cause less stress on the fan, thereby extending the fan's life.
