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

July 16, 2020

During the summer, using your air conditioning can be your largest monthly electrical cost. So, it’s only natural that you’re checking for methods to save. That may involve using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model through air conditioner installation.

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

Your air conditioner works with a fan to dispatch the cold air it creates. You manage this fan at your thermostat by switching it to “auto,” which indicates the fan will only work when the air conditioner is cooling. Or you can adjust it to “on,” which indicates it will operate all the time.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better stabilize your family’s comfort. This is ideal if you own a two-story residence, since areas upstairs can be more hot. It’s also good if you struggle with uneven cooling due to hot and cold rooms.

It’s also advantageous if someone in your household has allergies, asthma or other respiratory symptoms. That’s due to the fact the air is consistently being distributed and filtrated. However, you may have to switch your air filters more regularly.

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

Your house may also appear muggier. Air conditioning helps manage humidity by removing water from the air. But if the fan is always running, it’s challenging for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only go when your air conditioner does. It’s ideal if your home always seems comfortable, whichever room you’re in.

There are a few drawbacks to using the auto setting. You may run into hot and cold locations in your home and lower air quality. This is because air isn’t constantly moving or being continuously filtrated.

That said, you’ll use reduced energy and won’t be required to get a new air filter as regularly. Both are savings that can add up over the year, so you’ll have to think about what’s right for your home.
