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 utility expense. So, it’s only natural that you’re looking for ways to consume less energy. That can include finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner relies on a fan to deliver the cold air it makes. You adjust this fan at your thermostat by changing it to “auto,” which indicates the fan will only run when the air conditioner is running. Or you can set it to “on,” which indicates it will work continuously.

Does putting your AC on “fan” save energy in Milledgeville and Middle Georgia? Not necessarily. Generally, operating your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also offers a few pluses (and downsides) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better equalize your family’s comfort. This is great if you own a two-story house, since spaces upstairs can be more hot. It’s also ideal if you have problems with unbalanced cooling on account of hot and cold areas.

It’s also good if one of your family members has been diagnosed with allergies, asthma or other respiratory illnesses. That’s due to the fact the air is constantly being circulated and filtrated. On the flip side, you may have to replace your air filters more frequently.

Having the fan on all the time can also make your energy bills more expensive. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your residence may also appear muggier. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is always going, it’s more difficult for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only work when your air conditioner does. It’s great if your house always seems cool, whichever room you’re in.

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

On the flip side, you’ll consume reduced energy and won’t have to change your air filter as regularly. Both are savings that can add up throughout the year, so you’ll have to consider what’s best for your needs.
