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

July 16, 2020

During the summer, running your air conditioning can be your largest monthly electricity expense. So, it’s only natural that you’re seeking ways to consume less energy. That may entail finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model with air conditioner installation.

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

Your air conditioner uses a fan to dispatch the cool air it creates. You adjust 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 switch it to “on,” which means it will be on continuously.

Does putting your AC on “fan” save energy in Carpentersville? This isn’t always the case. Usually, using your air conditioner’s fan all day is going to increase your energy bill slightly.

But it also offers a few perks (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 continuously can better stabilize your family’s comfort. This is ideal if you have a two-story house, since areas upstairs can be warmer. It’s also good if you have problems with uneven cooling due to hot and cold spots.

It’s also advantageous if one of your family members has allergies, asthma or other respiratory symptoms. That’s due to the fact the air is constantly being circulated and filtered. On the flip side, 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 cause the fan to wear out faster and need air conditioning repair.

Your residence may also seem more humid. Air conditioning helps balance humidity by removing water from the air. But if the fan is constantly working, it’s harder for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

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

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

That said, you’ll consume less energy and won’t need to switch you air filter as frequently. Both are savings that can add up throughout the year, so you’ll have to think about what’s best for your household.
