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

July 16, 2020

During the summer, using your air conditioning can be your biggest monthly electricity expense. So, it’s given that you’re seeking approaches to consume less energy. That might involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

Switching your air conditioning’s fan setting is a second way you can spend less money.

Your air conditioner works with a fan to distribute the cold air it makes. You adjust this fan at your thermostat by switching it to “auto,” which indicates the fan will only run when the air conditioner is operating. Or you can switch it to “on,” which indicates it will run constantly.

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

But it also offers a few perks (and drawbacks) in regard 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 own a two-story house, since rooms upstairs can be warmer. It’s also great if you struggle with inconsistent cooling because of hot and cold rooms.

It’s also good if someone in your household deals with allergies, asthma or other respiratory illnesses. That’s due to the fact the air is consistently being circulated and filtrated. On the flip side, you may have to install new air filters more often.

Having the fan on all day can also increase your energy bills. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your residence may also appear more moist. Air conditioning helps manage humidity by clearing water from the air. But if the fan is continually on, it’s more difficult for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only go when your air conditioner does. It’s good if your home always feels cool, no matter what spot you’re in.

There are a few downsides to using the auto setting. You might have hot and cold spots in your residence and decreased air quality. This is due to the fact air isn’t always being distributed or being constantly filtrated.

That said, you’ll need less energy and won’t be required to replace your air filter as regularly. Both are savings that can build up over the year, so you’ll have to think about what’s best for your family.
