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

July 16, 2020

During the high temperatures, operating your air conditioning can be your largest monthly electricity charge. So, it’s given that you’re checking for ways to use less energy. That might entail trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system through air conditioner installation.

Adjusting your air conditioning’s fan setting is a second way you can save money.

Your air conditioner works with a fan to deliver the cool air it creates. You control this fan at your thermostat by switching it to “auto,” which signifies the fan will only be on when the air conditioner is operating. Or you can set it to “on,” which means it will run all the time.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better stabilize your family’s comfort. This is ideal if you have a two-story home, since spaces upstairs can be warmer. It’s also great if you have problems with unbalanced cooling on account of hot and cold spots.

It’s also advantageous if one of your loved ones has been diagnosed with allergies, asthma or other respiratory illnesses. That’s because the air is continuously being dispersed and purified. On the flip side, you may have to install new air filters more frequently.

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

Your residence may also seem more moist. Air conditioning helps control humidity by clearing wetness from the air. But if the fan is always going, it’s harder for moisture to flow from the condenser outside.

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 house always feels cool, whichever room you’re in.

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

On the other hand, you’ll use less energy and won’t be required to change your air filter as regularly. Both are savings that can build up during the year, so you’ll have to consider what’s right for your household.
