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

During the high temperatures, operating your air conditioning can be your highest monthly utility cost. So, it’s only natural that you’re seeking methods to save. That can include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model with air conditioner installation.

Changing your air conditioning’s fan setting is another way you can conserve money.

Your air conditioner relies on a fan to deliver the cool air it makes. You manage this fan at your thermostat by switching it to “auto,” which means the fan will only work when the air conditioner is running. Or you can adjust it to “on,” which signifies it will operate continuously.

Does putting your AC on “fan” save energy in Genoa? This isn’t always the case. Usually, using your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also provides a few advantages (and drawbacks) in relation 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 equalize your family’s comfort. This is good if you live in a two-story home, since spaces upstairs can be more hot. It’s also good if you struggle with inconsistent cooling because of hot and cold spaces.

It’s also good if someone in your household suffers from allergies, asthma or other respiratory symptoms. That’s since the air is constantly being dispersed and filtrated. However, you may have to switch your air filters more often.

Having the fan on constantly can also drive up your energy bills. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your home may also feel more moist. Air conditioning helps balance humidity by clearing wetness from the air. But if the fan is constantly running, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only operate when your air conditioner does. It’s good if your home always feels the right temperature, no matter what room you’re in.

There are a few drawbacks to using the auto setting. You could run into hot and cold spots in your house and reduced air quality. This is due to the fact air isn’t constantly moving or being continuously filtrated.

On the flip side, you’ll need less energy and won’t be required to change your air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to think over what’s right for your home.
