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

During the summer, running your air conditioning can be your biggest monthly utility expense. So, it’s normal that you’re seeking ways to consume less energy. That might entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

Adjusting 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 chilled air it makes. You adjust this fan at your thermostat by setting it to “auto,” which signifies the fan will only be on when the air conditioner is operating. Or you can switch it to “on,” which means it will operate constantly.

Does putting your AC on “fan” save energy in Excelsior Springs? Not necessarily. Usually, running your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also has a few advantages (and drawbacks) when it comes to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all the time can better stabilize your house’s comfort. This is good if you own a two-story residence, since rooms upstairs can be hotter. It’s also great if you have problems with uneven cooling on account of hot and cold spots.

It’s also beneficial if one of your family members has allergies, asthma or other respiratory illnesses. That’s since the air is continuously being distributed and purified. On the flip side, you may have to replace your air filters more regularly.

Having the fan on constantly can also drive up your energy bills. It could also cause the fan to wear out faster and need air conditioning repair.

Your home may also appear more humid. Air conditioning helps balance humidity by extracting water from the air. But if the fan is continually going, it’s more difficult for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only work when your air conditioner does. It’s ideal if your home always seems comfy, regardless of which room you’re in.

There are a few disadvantages to using the auto setting. You may have hot and cold areas in your house and decreased air quality. This is since air isn’t continuously flowing or being continuously filtrated.

That said, you’ll need reduced energy and won’t be required to get a new air filter as often. Both are savings that can build up throughout the year, so you’ll have to think about what’s best for your home.
