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

July 16, 2020

During the high temperatures, operating your air conditioning can be your highest monthly utility expense. So, it’s only natural that you’re looking for methods to use less energy. That can involve trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

Adjusting your air conditioning’s fan setting is a second way you can save money.

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

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

But it also provides a few perks (and drawbacks) as far as your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better balance your family’s comfort. This is good if you live in a two-story home, since spaces upstairs can be hotter. It’s also great if you have issues with unbalanced cooling due to hot and cold areas.

It’s also beneficial if one of your loved ones suffers from allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being distributed and purified. However, you may have to install new air filters more often.

Having the fan on all the time can also make your energy bills more expensive. It could also cause the fan to wear out faster and need air conditioning repair.

Your home may also seem more moist. Air conditioning helps manage humidity by extracting water from the air. But if the fan is continually going, it’s harder for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only go when your air conditioner does. It’s good if your house always appears comfortable, whichever area you’re in.

There are a few drawbacks to using the auto setting. You could have hot and cold areas in your residence and reduced air quality. This is since air isn’t always flowing or being repeatedly purified.

That said, you’ll use reduced energy and won’t be required to get a new air filter as frequently. Both are savings that can build up during the year, so you’ll have to think over what’s right for your needs.
