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

July 16, 2020

During the summer, using your air conditioning can be your largest monthly electrical charge. So, it’s normal that you’re looking for ways to consume less energy. That could involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model with air conditioner installation.

Changing your air conditioning’s fan setting is an additional way you can conserve money.

Your air conditioner works with a fan to distribute the chilled air it makes. You adjust 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 work all the time.

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

But it also gives a few perks (and downsides) as far as your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

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

It’s also beneficial if one of your family members suffers from allergies, asthma or other respiratory symptoms. That’s due to the fact the air is consistently being dispersed and filtrated. On the other hand, you may have to install new air filters more regularly.

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

Your residence may also feel muggier. Air conditioning helps control humidity by clearing water from the air. But if the fan is continually on, it’s harder for moisture to flow 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 ideal if your residence always appears cool, regardless of which area you’re in.

There are a few disadvantages to using the auto setting. You might have hot and cold areas in your home and reduced air quality. This is because air isn’t constantly moving or being continuously filtrated.

On the other hand, you’ll need less energy and won’t need to get a new air filter as regularly. Both are savings that can build up throughout the year, so you’ll have to think over what’s best for your household.
