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

July 16, 2020

During the high temperatures, running your air conditioning can be your largest monthly utility expense. So, it’s only natural that you’re checking for methods to save. That could include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system during air conditioner installation.

Adjusting your air conditioning’s fan setting is another way you can conserve money.

Your air conditioner uses a fan to distribute the cool air it makes. You adjust this fan at your thermostat by changing it to “auto,” which signifies the fan will only work when the air conditioner is operating. Or you can set it to “on,” which means it will work continuously.

Does putting your AC on “fan” save energy in Hudsonville? This isn’t always the case. Typically, operating your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also provides a few advantages (and disadvantages) in regard to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better stabilize your house’s comfort. This is great if you live in a two-story house, since spaces upstairs can be more hot. It’s also ideal if you have problems with unbalanced cooling because of hot and cold spots.

It’s also good if one of your loved ones has been diagnosed with allergies, asthma or other respiratory problems. That’s since the air is consistently being dispersed and filtered. However, you may have to install new air filters more regularly.

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

Your home may also seem muggier. Air conditioning helps control humidity by clearing moisture from the air. But if the fan is constantly going, it’s harder for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only operate when your air conditioner does. It’s good if your house always appears cool, regardless of which spot you’re in.

There are a few disadvantages to using the auto setting. You could have hot and cold areas in your house and decreased air quality. This is due to the fact air isn’t continuously being distributed or being repeatedly filtrated.

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