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

July 16, 2020

During the hot weather, running your air conditioning can be your highest monthly electrical expense. So, it’s only natural that you’re looking for approaches to consume less energy. That could involve using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

Switching your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner uses a fan to distribute the cold air it produces. You control this fan at your thermostat by switching it to “auto,” which indicates the fan will only be on when the air conditioner is running. Or you can switch it to “on,” which indicates it will be on constantly.

Does putting your AC on “fan” save energy in Belton? Not always. Usually, operating your air conditioner’s fan all the time is going to make your energy bill slightly higher.

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 run all the time can better equalize your house’s comfort. This is great if you have a two-story home, since areas upstairs can be hotter. It’s also ideal if you have difficulties with uneven cooling on account of hot and cold spaces.

It’s also advantageous if one of your loved ones suffers from allergies, asthma or other respiratory symptoms. That’s since the air is continuously being dispersed and filtered. 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 result in the fan wearing out sooner and need air conditioning repair.

Your residence may also seem muggier. Air conditioning helps manage humidity by extracting water from the air. But if the fan is continuously running, it’s harder for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

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

There are a few disadvantages to using the auto setting. You may experience hot and cold spots in your residence and reduced air quality. This is because air isn’t continuously moving or being repeatedly filtrated.

On the flip side, you’ll need less energy and won’t need to change your air filter as often. Both are savings that can build up during the year, so you’ll have to think about what’s best for your household.
