Should You Keep Your AC on “Auto” or “On”?

A Smiling Man Adjusting Thermostat On Home Heating System

Should I keep the AC on or on “Auto”? This is a question that many homeowners in Southwestern Florida grapple with every year. The correct answer for your home depends on your needs and desired comfort. Each choice has advantages and drawbacks, and understanding these will help you make an informed decision for your comfort.

Understanding “On” and “Auto”

When the fan is set to “On,” it operates 24/7. This ensures the even distribution of cool air throughout the home. It’s not energy-efficient, but it will provide the most comfortable environment within each room in the house.

When the unit is set to “Auto,” it will run only when the heating or cooling system is in use. This energy-efficient setting keeps the fan operating at the minimum speed for a minimum period of time. Once the thermostat indicates the desired temperature is reached, the fan will turn off and idle until the next cycle.

Advantages & Drawbacks of “On”

When the system is set to “On,” it will continuously cycle air through the ducts in your home. This will ensure an even temperature in every room and the highest indoor air quality because it removes more indoor air pollutants as it runs.

However, this comfort comes at a cost. It increases wear and tear on your HVAC system and significantly increases your cooling costs. And in the humid Southwestern Florida climate, this also means that the humidity levels within the home can build up quickly.

Advantages & Drawbacks of “Auto”

When the fan is set to “Auto,” it will operate at the minimum required level for your comfort. This helps keep your air filter cleaner and helps keep humidity levels within the home from rising. It also keeps your utility bills from heating up.

But the grass isn’t all greener. The frequent starts and stops of the fan can increase wear and tear on the air conditioner. This can lead to increased repair frequency and premature system failure. It also means that while your home will be comfortable, it won’t be as comfortable as you may like.

Which Setting Is Best?

“Auto” is recommended for times when you are out of the house (i.e., at work, on vacation, etc.). This setting is also recommended if you want to keep your utility bills down and preserve system reliability.

“On” is best for homes that are occupied throughout the day or when someone in the house has allergies or other respiratory conditions that indoor air pollutants can exacerbate.

Of course, your needs are likely to change throughout the season. That is one reason why installing a programmable thermostat is strongly recommended. Programmable thermostats make it easy to adjust your settings as your needs change and evolve. This gives you superior control over your comfort and greater control over your energy usage. It’s like having your cake and eating it, too.
