Which Uses 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 charge. So, it’s normal that you’re looking for ways to consume less energy. That may entail using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit with air conditioner installation.

Modifying your air conditioning’s fan setting is another way you can save money.

Your air conditioner relies on a fan to deliver the chilled air it produces. You manage this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is running. Or you can switch it to “on,” which indicates it will work constantly.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better equalize your family’s comfort. This is ideal if you own a two-story residence, since rooms upstairs can be hotter. It’s also great if you have issues with unbalanced cooling due to hot and cold areas.

It’s also advantageous if one of your loved ones has been diagnosed with allergies, asthma or other respiratory symptoms. That’s because the air is constantly being dispersed and filtrated. On the other hand, you may have to put in new air filters more regularly.

Having the fan on all the time can also drive up your energy bills. It could also make the fan wear out faster and need air conditioning repair.

Your home may also appear more humid. Air conditioning helps manage humidity by removing wetness from the air. But if the fan is continually on, it’s harder for moisture to drain from the condenser externally.

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 ideal if your home always seems the right temperature, no matter what room you’re in.

There are a few drawbacks to using the auto setting. You might have hot and cold areas in your residence and decreased air quality. This is because air isn’t continuously flowing or being constantly filtrated.

On the flip side, you’ll require less energy and won’t need to get a new air filter as frequently. Both are savings that can build up over the year, so you’ll have to consider what’s ideal for your home.
