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

July 16, 2020

During the high temperatures, operating your air conditioning can be your largest monthly utility cost. So, it’s only natural that you’re seeking approaches to use less energy. That can include trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

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

Your air conditioner works with a fan to deliver the cool air it produces. You control this fan at your thermostat by switching it to “auto,” which indicates the fan will only work when the air conditioner is running. Or you can switch it to “on,” which signifies it will work constantly.

Does putting your AC on “fan” save energy in Mankato area? This isn’t always the case. Usually, operating your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also provides a few advantages (and drawbacks) as far as your home’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 house’s comfort. This is ideal if you live in a two-story residence, since spaces upstairs can be more hot. It’s also good if you struggle with uneven cooling due to hot and cold spots.

It’s also advantageous if someone in your household deals with allergies, asthma or other respiratory issues. That’s since the air is constantly being distributed and purified. On the flip side, you may have to change your air filters more regularly.

Having the fan on all the time can also drive up your energy bills. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your house may also feel muggier. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is always working, it’s harder for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only run when your air conditioner does. It’s ideal if your residence always seems cool, whichever spot you’re in.

There are a few downsides to using the auto setting. You may experience hot and cold spots in your home and lower air quality. This is since air isn’t continuously being distributed or being continuously filtered.

On the other hand, you’ll use less energy and won’t need to change your air filter as often. Both are savings that can tally up throughout the year, so you’ll have to think over what’s ideal for your needs.
