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

July 16, 2020

During the hot weather, operating your air conditioning can be your highest monthly electricity expense. So, it’s only natural that you’re checking for approaches to use less energy. That might involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit through air conditioner installation.

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

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

Does putting your AC on “fan” save energy in South Beloit and Belvidere? This isn’t always the case. Usually, running your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also offers a few pluses (and disadvantages) as far as your residence’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 residence, since areas upstairs can be hotter. It’s also good if you have difficulties with uneven cooling due to hot and cold spaces.

It’s also advantageous if one of your loved ones has allergies, asthma or other respiratory symptoms. That’s because the air is continuously being circulated and purified. On the flip side, you may have to put in new air filters more regularly.

Having the fan on all day can also drive up your energy bills. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your home may also feel muggier. Air conditioning helps manage humidity by clearing water from the air. But if the fan is always running, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only operate when your air conditioner does. It’s great if your home always appears comfy, no matter what room you’re in.

There are a few disadvantages to using the auto setting. You may experience hot and cold locations in your home and decreased air quality. This is because air isn’t constantly moving or being constantly filtered.

On the flip side, you’ll require reduced energy and won’t have to replace your air filter as often. Both are savings that can tally up during the year, so you’ll have to consider what’s best for your needs.
