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

July 16, 2020

During the summer, using your air conditioning can be your highest monthly utility expense. So, it’s given that you’re checking for ways to use less energy. That could entail trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system with air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cool air it makes. You control this fan at your thermostat by changing it to “auto,” which means the fan will only be on when the air conditioner is running. Or you can adjust it to “on,” which signifies it will be on continuously.

Does putting your AC on “fan” save energy in Fort Lauderdale? This isn’t always the case. Generally, using your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also provides a few perks (and drawbacks) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all the time can better stabilize your family’s comfort. This is good if you own a two-story house, since rooms upstairs can be warmer. It’s also ideal if you have issues with uneven cooling on account of hot and cold spots.

It’s also beneficial if someone in your household deals with allergies, asthma or other respiratory symptoms. That’s because the air is consistently being dispersed and purified. On the flip side, you may have to put in new air filters more frequently.

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 seem more moist. Air conditioning helps control humidity by extracting moisture from the air. But if the fan is constantly running, it’s harder for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only run when your air conditioner does. It’s ideal if your residence always feels cool, no matter what room you’re in.

There are a few downsides to using the auto setting. You may experience hot and cold locations in your house and decreased air quality. This is due to the fact air isn’t continuously moving or being repeatedly filtrated.

That said, you’ll require reduced energy and won’t be required to replace your air filter as regularly. Both are savings that can add up throughout the year, so you’ll have to consider what’s ideal for your household.
