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

July 16, 2020

During the summer, using your air conditioning can be your largest monthly electricity expense. So, it’s given that you’re checking for methods to use less energy. That may involve finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model during air conditioner installation.

Switching your air conditioning’s fan setting is a second way you can spend less money.

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

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better stabilize your family’s comfort. This is great if you live in a two-story house, since rooms upstairs can be warmer. It’s also ideal if you have difficulties with uneven cooling due to hot and cold spots.

It’s also good if someone in your household deals with allergies, asthma or other respiratory issues. That’s since the air is continuously being distributed and purified. On the other hand, you may have to switch your air filters more often.

Having the fan on constantly can also increase your energy bills. It could also make the fan wear out faster and need air conditioning repair.

Your home may also seem more moist. Air conditioning helps balance humidity by extracting moisture from the air. But if the fan is continually working, it’s more difficult for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only work when your air conditioner does. It’s good if your home always appears cool, whichever area you’re in.

There are a few downsides to using the auto setting. You may experience hot and cold areas in your residence and decreased air quality. This is due to the fact air isn’t always moving or being continuously filtered.

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