Your thermostat has two fan settings: auto and on. Using the right setting will help you manage your indoor air quality, the temperature in your home, and the energy efficiency of your HVAC system properly. Learn how your HVAC fan settings work so that you can always choose the right one for your Childersburg, Alabama, home.

When to Use the "Auto" Setting

The "auto" setting on your thermostat will cause the fan to run whenever the system is running. This means that the fan will turn on when your air conditioner or heater starts and turn off when your home has reached the programmed temperature. This is the best choice for daily use. Using the fan only when your heating or cooling systems are running will save energy, while running the fan continuously will strain both the fan and your utility bill. Choose "auto" as your default setting.

When to Use the "On" Setting

If you set the fan to "on," it will run until you turn it back to "auto." If you’re not mindful when using this setting, you could inadvertently leave the fan running nonstop for days or weeks. In most cases, you’ll be fine using the "auto" setting. However, there are a few situations when having the fan on can be helpful. These include:

  • When you’re cleaning: Turning on the fan will help pull dust from the air as it’s being stirred up.
  • If the temperature outside is comfortable: Turning on the fan for a few hours will circulate air throughout your home, keeping things fresh when you need neither heating nor cooling.
  • When you have guests: Maintaining fresh air and consistent temperatures is tricky when you have a lot of visitors in your house. Running the fan will help with both issues.
