“On” Versus “Auto” Settings

In addition to the temperature setting on your thermostat, you must choose between “on” or “auto.” This setting controls the fan on your HVAC system and has major efficiency implications.

If you choose the automatic thermostat setting, the fan on your HVAC unit will only run when either the air conditioning or the heating cycle is running. Unless you are experiencing HVAC problems, when the temperature in your home reaches the thermostat temperature you have chosen, the heating or the air conditioning unit stops running as does the fan. However, if you choose the “on” setting, the fan continues to run even when the heating or the air conditioning unit stops.

Is the “auto” setting better for the fan?digital thermostats granite city il

Many people believe that the “auto” setting for the thermostat is better than allowing the fan to run continuously because you save money by not running the fan when the heating or air conditioning cycles are not running. However, there are some advantages to setting your fan to the “on” position.

When your fan is continuously running, the unit can distribute the air in your home more evenly. By using the automatic setting, the fan only moves air throughout your home when the HVAC system is running. Moving air throughout your home continuously can reduce hot and cold spots because the air is distributed evenly. Another benefit of this setting is that the air inside your home is constantly being cycled through the air filter. This may help improve air quality.

Furthermore, using the “auto” setting can cause unnecessary wear and tear on your heating and cooling systems. You can experience HVAC problems in the future because of the constant “starting and stopping” of the fan. On the other hand, the “on” setting may cause wear and tear caused by the continued operation of the fan.
