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

July 16, 2020

During the hot weather, using your air conditioning can be your highest monthly electrical cost. So, it’s only natural that you’re looking for ways to use less energy. That might include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system during air conditioner installation.

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

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

Does putting your AC on “fan” save energy in Circleville? Not always. Typically, operating your air conditioner’s fan constantly is going to increase your energy bill slightly.

But it also has a few advantages (and drawbacks) in relation to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better stabilize your house’s comfort. This is good if you own a two-story house, since spaces upstairs can be hotter. It’s also ideal if you have problems with unbalanced cooling because of hot and cold rooms.

It’s also advantageous if one of your loved ones suffers from allergies, asthma or other respiratory problems. That’s since the air is consistently being dispersed and filtered. However, you may have to put in new air filters more frequently.

Having the fan on all day can also increase your energy bills. It could also make the fan wear out sooner and need air conditioning repair.

Your residence may also appear more humid. Air conditioning helps control humidity by removing water from the air. But if the fan is constantly working, it’s harder for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only run when your air conditioner does. It’s ideal if your home always feels comfortable, regardless of which spot you’re in.

There are a few downsides to using the auto setting. You could run into hot and cold areas in your residence and reduced air quality. This is because air isn’t always being distributed or being continuously purified.

That said, you’ll use reduced energy and won’t have to get a new air filter as regularly. Both are savings that can tally up during the year, so you’ll have to think about what’s ideal for your needs.
