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

During the high temperatures, operating your air conditioning can be your highest monthly utility cost. So, it’s given that you’re seeking methods to use less energy. That might entail trying 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 an additional way you can conserve money.

Your air conditioner relies on a fan to distribute the chilled air it makes. You manage this fan at your thermostat by switching it to “auto,” which means the fan will only run when the air conditioner is cooling. Or you can set it to “on,” which means it will run continuously.

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

But it also offers a few perks (and drawbacks) when it comes to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better equalize your family’s comfort. This is good if you have a two-story home, since areas upstairs can be warmer. It’s also great if you have issues with unbalanced cooling because of hot and cold areas.

It’s also beneficial 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 purified. However, you may have to install new air filters more frequently.

Having the fan on all the time can also drive up your energy bills. It could also make the fan wear out prematurely and need air conditioning repair.

Your home may also seem more humid. Air conditioning helps balance humidity by drawing moisture from the air. But if the fan is constantly on, it’s challenging for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

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

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

On the flip side, you’ll require a lower amount of energy and won’t need to change your air filter as often. Both are savings that can add up throughout the year, so you’ll have to think about what’s best for your home.
