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

July 16, 2020

During the hot weather, operating your air conditioning can be your biggest monthly electrical expense. So, it’s only natural that you’re seeking ways to save. That might involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model through air conditioner installation.

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

Your air conditioner uses a fan to deliver the cool air it creates. You adjust this fan at your thermostat by changing it to “auto,” which indicates the fan will only work when the air conditioner is going. Or you can switch it to “on,” which means it will be on continuously.

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

But it also gives a few advantages (and downsides) as far as your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better balance your family’s comfort. This is great if you live in a two-story residence, since areas upstairs can be more hot. It’s also great if you struggle with inconsistent cooling on account of hot and cold spots.

It’s also beneficial if one of your family members suffers from allergies, asthma or other respiratory symptoms. That’s since the air is constantly being distributed and filtrated. On the flip side, you may have to install new air filters more regularly.

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

Your house may also seem more moist. Air conditioning helps control humidity by extracting 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, because the fan will only work when your air conditioner does. It’s ideal if your residence always seems pleasant, no matter what area you’re in.

There are a few downsides to using the auto setting. You could run into hot and cold areas in your residence and decreased air quality. This is because air isn’t continuously being distributed or being constantly filtrated.

That said, you’ll consume reduced energy and won’t be required to replace your air filter as often. Both are savings that can tally up throughout the year, so you’ll have to think over what’s best for your home.
