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

July 16, 2020

During the high temperatures, using your air conditioning can be your biggest monthly electricity cost. So, it’s given that you’re looking for methods to consume less energy. That can entail using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner uses a fan to deliver the cool 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 cooling. Or you can switch it to “on,” which indicates it will be on all the time.

Does putting your AC on “fan” save energy in Bossier City? Not always. Usually, running your air conditioner’s fan all the time is going to increase your energy bill slightly.

But it also has a few perks (and downsides) as far as your home’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 home’s comfort. This is good if you own a two-story house, since areas upstairs can be hotter. It’s also ideal if you have issues with inconsistent cooling due to hot and cold spaces.

It’s also great if someone in your household suffers from allergies, asthma or other respiratory issues. That’s since the air is consistently being circulated and filtrated. On the other hand, you may have to switch your air filters more regularly.

Having the fan on constantly can also drive up your energy bills. It could also result in the fan wearing out more quickly and need air conditioning repair.

Your home may also appear more moist. Air conditioning helps control humidity by extracting wetness from the air. But if the fan is continually running, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only go when your air conditioner does. It’s good if your house always appears comfortable, no matter what room you’re in.

There are a few disadvantages to using the auto setting. You might experience hot and cold spots in your house and decreased air quality. This is because air isn’t always moving or being constantly filtrated.

On the other hand, you’ll use reduced energy and won’t be required to replace your air filter as often. Both are savings that can add up during the year, so you’ll have to think over what’s best for your family.
