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

During the high temperatures, using your air conditioning can be your highest monthly utility charge. So, it’s given that you’re seeking methods to consume less energy. That might include using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cold air it creates. You adjust this fan at your thermostat by setting 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 indicates it will be on continuously.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better stabilize your home’s comfort. This is great if you live in a two-story home, since rooms upstairs can be warmer. It’s also great if you have issues with unbalanced cooling because of hot and cold spots.

It’s also advantageous if one of your loved ones has been diagnosed with allergies, asthma or other respiratory issues. That’s due to the fact the air is constantly being distributed and purified. However, you may have to replace your air filters more often.

Having the fan on all the time can also increase your energy bills. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your home may also feel more moist. Air conditioning helps control humidity by clearing water from the air. But if the fan is always going, it’s challenging for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only run when your air conditioner does. It’s ideal if your house always seems cool, regardless of which room you’re in.

There are a few downsides to using the auto setting. You may have hot and cold spots in your house and reduced air quality. This is since air isn’t always being distributed or being constantly purified.

On the flip side, you’ll need a lower amount of energy and won’t need to get a new air filter as regularly. Both are savings that can tally up over the year, so you’ll have to think over what’s best for your needs.
