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

July 16, 2020

During the high temperatures, running your air conditioning can be your largest monthly electricity expense. So, it’s given that you’re looking for methods to consume less energy. That might include using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model during air conditioner installation.

Adjusting your air conditioning’s fan setting is an additional way you can save money.

Your air conditioner uses a fan to dispatch the chilled air it creates. You control this fan at your thermostat by changing it to “auto,” which signifies the fan will only work when the air conditioner is cooling. Or you can adjust it to “on,” which means it will run constantly.

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

But it also provides a few perks (and disadvantages) as far as your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better equalize your home’s comfort. This is great if you live in a two-story home, since areas upstairs can be hotter. It’s also ideal if you struggle with unbalanced cooling on account of hot and cold rooms.

It’s also beneficial if one of your family members deals with allergies, asthma or other respiratory issues. That’s because the air is consistently being distributed and purified. On the flip side, you may have to put in new air filters more frequently.

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

Your home may also feel more moist. Air conditioning helps balance humidity by drawing water from the air. But if the fan is constantly running, it’s challenging 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 operate when your air conditioner does. It’s ideal if your residence always seems the right temperature, no matter what room you’re in.

There are a few downsides to using the auto setting. You might have hot and cold locations in your home and reduced air quality. This is because air isn’t constantly flowing or being repeatedly purified.

On the other hand, you’ll use reduced energy and won’t be required to switch you air filter as often. Both are savings that can tally up during the year, so you’ll have to consider what’s ideal for your home.
