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

July 16, 2020

During the high temperatures, running your air conditioning can be your highest monthly electricity expense. So, it’s normal that you’re looking for approaches to use less energy. That can entail using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system during air conditioner installation.

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

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

Does putting your AC on “fan” save energy in Plover? Not necessarily. Typically, using your air conditioner’s fan constantly is going to increase your energy bill slightly.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better equalize your home’s comfort. This is great if you live in a two-story house, since spaces upstairs can be more hot. It’s also good if you have difficulties with uneven cooling on account of hot and cold rooms.

It’s also advantageous if one of your family members deals with allergies, asthma or other respiratory problems. That’s since the air is continuously being distributed and purified. On the flip side, you may have to put in 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 residence may also appear more moist. Air conditioning helps manage humidity by clearing wetness from the air. But if the fan is continually running, it’s more difficult for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only run when your air conditioner does. It’s good if your residence always feels cool, no matter what spot you’re in.

There are a few downsides to using the auto setting. You may run into hot and cold locations in your residence and reduced air quality. This is because air isn’t constantly flowing or being continuously filtered.

That said, you’ll need less energy and won’t need to replace your air filter as regularly. Both are savings that can tally up over the year, so you’ll have to think about what’s best for your needs.
