If you own a standard thermostat, you’ve probably noticed a couple of options that you can either select on a display screen or choose with a switch: AUTO and ON. Now, you’re probably wondering:

• What is the difference between these settings?
• Which one is best for heating/cooling my home?

Below, we’ll provide answers to all of these questions so that you can better understand how to utilize your home’s thermostat.

What’s the Difference Between ON and AUTO on My Thermostat?

Your thermostat is your heating and cooling system’s “command center.” AUTO and ON are two separate commands for your system.

• AUTO: This tells your system to keep running until the thermostat detects that your home has reached your desired temperature.
• ON: This tells your system to keep its fan running continuously, even when your home has reached your desired temperature. The fan will continue to circulate air throughout your home, even when your system is not heating or cooling the air.

Which Setting Is Best for Heating and Cooling My Home?

Both settings have their benefits and drawbacks:

• AUTO: This is the most energy-efficient setting because it only requires your system to run when your home falls below your desired temperature. Your filter will also stay cleaner longer because the fan isn’t running as often. The downside is that more frequent starting and stopping can wear out the fan’s parts faster than letting the fan run continuously.
• ON: This setting is less energy-efficient because your system requires energy to keep the fan blowing constantly. You might also notice that the air coming out of the vents will feel room temperature after a while. On the plus side, your home can get cleaner air and may feel like it’s warmed or cooled more evenly. You’re also less likely to rack up wear-and-tear on the fan because it isn’t starting and stopping as much.

You’ll need to weigh these pros and cons to determine which setting is best for your household.

What If I Want to Save Energy and Have Even Temperatures in My Home?

Ultimately, installing a zoning system is the most effective way to save energy and achieve maximum temperature control. A zoning system works with your HVAC system, and you use it to control which areas of your home receive hot or cold air.
