Which Uses Less Energy? AC Fan On or in Auto?

July 16, 2020

During the summer, operating your air conditioning can be your biggest monthly electricity charge. So, it’s given that you’re looking for ways to consume less energy. That may include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

Modifying your air conditioning’s fan setting is a second way you can save money.

Your air conditioner uses a fan to distribute the chilled air it produces. You manage this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is operating. Or you can set it to “on,” which signifies it will run continuously.

Does putting your AC on “fan” save energy in Omaha? Not necessarily. Usually, running your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also provides a few perks (and disadvantages) in regard to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better balance your family’s comfort. This is ideal if you live in a two-story residence, since areas upstairs can be more hot. It’s also great if you have issues with uneven cooling due to hot and cold spaces.

It’s also beneficial if one of your family members suffers from allergies, asthma or other respiratory symptoms. That’s because the air is constantly being dispersed and filtered. However, you may have to put in new air filters more regularly.

Having the fan on all the time can also increase your energy bills. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your residence may also feel muggier. Air conditioning helps control humidity by drawing moisture from the air. But if the fan is constantly on, it’s harder for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only operate when your air conditioner does. It’s good if your home always seems pleasant, no matter what area you’re in.

There are a few downsides to using the auto setting. You may have hot and cold areas in your house and lower air quality. This is due to the fact air isn’t constantly flowing or being continuously filtrated.

On the flip side, you’ll consume reduced energy and won’t be required to change your air filter as regularly. Both are savings that can tally up over the year, so you’ll have to consider what’s right for your family.
