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

July 16, 2020

During the hot weather, operating your air conditioning can be your largest monthly electrical charge. So, it’s given that you’re seeking methods to use less energy. That can include finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

Adjusting your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner uses a fan to deliver the cool air it makes. You manage this fan at your thermostat by setting it to “auto,” which means the fan will only be on when the air conditioner is cooling. Or you can adjust it to “on,” which indicates it will be on continuously.

Does putting your AC on “fan” save energy in Siloam Springs? Not always. Usually, running your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also provides a few advantages (and drawbacks) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better stabilize your house’s comfort. This is great if you own a two-story home, since rooms upstairs can be more hot. It’s also good if you have problems with unbalanced cooling because of hot and cold rooms.

It’s also advantageous if one of your loved ones has been diagnosed with allergies, asthma or other respiratory illnesses. That’s because the air is continuously being dispersed and filtered. On the flip side, you may have to put in new air filters more often.

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

Your residence may also feel more moist. Air conditioning helps control humidity by clearing moisture from the air. But if the fan is always on, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only operate when your air conditioner does. It’s ideal if your house always appears cool, regardless of which spot you’re in.

There are a few drawbacks to using the auto setting. You might have hot and cold locations in your home and reduced air quality. This is since air isn’t continuously being distributed or being repeatedly filtered.

On the flip side, you’ll require a lower amount of energy and won’t have to change your air filter as frequently. Both are savings that can tally up during the year, so you’ll have to think about what’s ideal for your needs.
