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

July 16, 2020

During the high temperatures, running your air conditioning can be your highest monthly electricity expense. So, it’s normal that you’re looking for approaches to save. That could involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit with air conditioner installation.

Regulating your air conditioning’s fan setting is a second way you can conserve money.

Your air conditioner works with a fan to deliver the chilled air it produces. You manage this fan at your thermostat by setting it to “auto,” which means the fan will only be on when the air conditioner is operating. Or you can adjust it to “on,” which means it will be on all the time.

Does putting your AC on “fan” save energy in Kirkfield Heating? Not necessarily. Typically, operating your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also has a few pluses (and downsides) when it comes to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better stabilize your home’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 unbalanced cooling because of hot and cold spaces.

It’s also advantageous if one of your loved ones deals with allergies, asthma or other respiratory symptoms. That’s since the air is constantly being dispersed and purified. However, you may have to replace your air filters more often.

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

Your home may also feel muggier. Air conditioning helps control humidity by extracting water from the air. But if the fan is continually going, it’s harder for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only work when your air conditioner does. It’s great if your home always seems comfy, regardless of which room you’re in.

There are a few drawbacks to using the auto setting. You may run into hot and cold spots in your residence and decreased air quality. This is because air isn’t continuously flowing or being repeatedly filtrated.

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