Should I Keep My AC on “Auto” or “On”?

Posted on: June 25, 2018

Wondering which setting for your air conditioner is best is a great question to ask. Most people don’t know the difference between the “auto” and “on” settings on your thermostat.

“Auto” Is Best If:

You’re out of the house a lot, or just want to keep energy use and costs down.

“On” Is Best If:

There’s family at home all day or someone in the household is an allergy sufferer, so evenly distributed air temperature and quality throughout your home is your top priority.

How the “Auto” Setting Works

The fan runs for either heating or cooling as needed with the “Auto” setting. This is an energy-saving mode, as the fan runs at the minimum necessary speed, and for the minimum lengths of time. Note a couple of other key benefits here too: your furnace filter won’t get dirty as quickly, and will last longer. And you get a better dehumidifying effect. When the fan is set to “On” the humidity keeps recycling back into your house and your unit uses even more energy processing the extra moisture. That said, your fan starts and stops more when running on “Auto.” That’s more wear and tear on the HVAC system over time.

How the “On” Setting Works

When you set your fan to “ON,” it runs 24/7. This mode distributes the heat or cooling through your home, including hard-to-reach areas. You’ll get the highest air quality in all parts of the home. This tends to be the more expensive setting, comparable to running a second refrigerator 24/7.
