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

July 16, 2020

During the summer, running your air conditioning can be your highest monthly electrical charge. So, it’s given that you’re checking for methods to consume less energy. That could involve finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit with air conditioner installation.

Regulating your air conditioning’s fan setting is a second way you can conserve money.

Your air conditioner works with a fan to dispatch the cool air it makes. You control this fan at your thermostat by switching it to “auto,” which indicates the fan will only be on when the air conditioner is cooling. Or you can set it to “on,” which means it will run constantly.

Does putting your AC on “fan” save energy in Menomonie and western Wisconsin? This isn’t always the case. Typically, using your air conditioner’s fan constantly is going to increase your energy bill slightly.

But it also provides a few perks (and drawbacks) when it comes to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better equalize your family’s comfort. This is great if you own a two-story residence, since areas upstairs can be hotter. It’s also ideal if you have issues with inconsistent cooling because of hot and cold spaces.

It’s also beneficial if one of your loved ones suffers from allergies, asthma or other respiratory symptoms. That’s due to the fact the air is constantly being circulated and filtered. On the flip side, you may have to replace your 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 prematurely and need air conditioning repair.

Your home may also appear more humid. Air conditioning helps balance humidity by removing water from the air. But if the fan is constantly working, it’s challenging for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only run when your air conditioner does. It’s good if your home always appears comfortable, whichever spot you’re in.

There are a few drawbacks to using the auto setting. You could have hot and cold areas in your home and reduced air quality. This is due to the fact air isn’t constantly moving or being repeatedly filtrated.

On the other hand, you’ll need a lower amount of energy and won’t need to replace your air filter as often. Both are savings that can build up during the year, so you’ll have to think over what’s ideal for your family.
