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

July 16, 2020

During the high temperatures, running your air conditioning can be your biggest monthly utility expense. So, it’s normal that you’re looking for methods to use less energy. That can involve finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner relies on a fan to deliver the cool air it makes. You adjust this fan at your thermostat by switching it to “auto,” which indicates the fan will only run when the air conditioner is cooling. Or you can adjust it to “on,” which means it will run constantly.

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

But it also provides a few perks (and disadvantages) when it comes 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 equalize your house’s comfort. This is ideal if you have a two-story house, since areas upstairs can be more hot. It’s also good if you have difficulties with unbalanced cooling because of hot and cold areas.

It’s also great if one of your family members suffers from allergies, asthma or other respiratory problems. That’s because the air is continuously being dispersed and filtered. However, you may have to put in new air filters more often.

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

Your home may also feel muggier. Air conditioning helps balance humidity by removing wetness from the air. But if the fan is constantly going, it’s more difficult for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only operate when your air conditioner does. It’s great if your home always appears cool, whichever spot you’re in.

There are a few drawbacks to using the auto setting. You could run into hot and cold locations in your house and reduced air quality. This is since air isn’t always moving or being constantly purified.

On the flip side, you’ll consume 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 right for your needs.
