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

July 16, 2020

During the high temperatures, using your air conditioning can be your biggest monthly electricity charge. So, it’s normal that you’re looking for approaches to use less energy. That can involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model through air conditioner installation.

Modifying your air conditioning’s fan setting is a second way you can conserve money.

Your air conditioner relies on a fan to distribute the chilled air it creates. You adjust this fan at your thermostat by changing it to “auto,” which signifies the fan will only work when the air conditioner is running. Or you can set it to “on,” which means it will work all the time.

Does putting your AC on “fan” save energy in Murrieta? Not always. Typically, using your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also offers a few perks (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 operate continuously can better equalize your family’s comfort. This is ideal if you own a two-story residence, since areas upstairs can be warmer. It’s also great if you have problems with unbalanced cooling because of hot and cold spots.

It’s also advantageous if someone in your household has allergies, asthma or other respiratory symptoms. That’s because the air is consistently being distributed and purified. However, you may have to install new air filters more often.

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

Your residence may also seem more humid. Air conditioning helps manage humidity by drawing wetness from the air. But if the fan is constantly on, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only run when your air conditioner does. It’s ideal if your residence always seems comfortable, no matter what room you’re in.

There are a few disadvantages to using the auto setting. You could have hot and cold locations in your house and reduced air quality. This is due to the fact air isn’t constantly flowing or being continuously purified.

That said, you’ll need reduced energy and won’t need to get a new air filter as regularly. Both are savings that can add up during the year, so you’ll have to think over what’s best for your family.
