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

July 16, 2020

During the hot weather, using your air conditioning can be your highest monthly utility expense. So, it’s given that you’re seeking approaches to consume less energy. That may involve finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit with air conditioner installation.

Switching your air conditioning’s fan setting is another way you can spend less money.

Your air conditioner uses a fan to distribute the chilled air it makes. You adjust this fan at your thermostat by switching it to “auto,” which indicates the fan will only be on when the air conditioner is running. Or you can adjust it to “on,” which indicates it will run continuously.

Does putting your AC on “fan” save energy in Moline? Not necessarily. Usually, operating your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also has a few perks (and drawbacks) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better stabilize your house’s comfort. This is great if you live in a two-story home, since areas upstairs can be warmer. It’s also good if you have difficulties with inconsistent cooling because of hot and cold areas.

It’s also beneficial if one of your loved ones deals with allergies, asthma or other respiratory problems. That’s since the air is constantly being distributed and filtered. However, you may have to change your air filters more regularly.

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

Your residence may also feel more humid. Air conditioning helps manage humidity by drawing water from the air. But if the fan is constantly running, it’s challenging for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only work when your air conditioner does. It’s ideal if your home always appears the right temperature, no matter what spot you’re in.

There are a few downsides to using the auto setting. You might experience hot and cold spots in your home and reduced air quality. This is due to the fact air isn’t constantly being distributed or being continuously filtrated.

That said, you’ll consume less energy and won’t need to change your air filter as often. Both are savings that can add up over the year, so you’ll have to think over what’s ideal for your family.
