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

July 16, 2020

During the high temperatures, running your air conditioning can be your highest monthly electrical charge. So, it’s normal that you’re looking for methods to save. That could involve finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit 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 produces. You adjust this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is going. Or you can adjust it to “on,” which means it will run all the time.

Does putting your AC on “fan” save energy in Reinholds? Not necessarily. Usually, running your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also provides a few pluses (and downsides) in regard to your family’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 good if you own a two-story house, since rooms upstairs can be more hot. It’s also great if you have problems with unbalanced cooling because of hot and cold spaces.

It’s also good if one of your family members suffers from allergies, asthma or other respiratory issues. That’s because the air is continuously being circulated and filtrated. However, you may have to switch your air filters more regularly.

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

Your house may also seem more humid. Air conditioning helps balance humidity by removing water from the air. But if the fan is always working, it’s challenging for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only operate when your air conditioner does. It’s good if your residence always feels the right temperature, whichever area you’re in.

There are a few downsides to using the auto setting. You might run into hot and cold spots in your house and lower air quality. This is because air isn’t continuously being distributed or being continuously filtrated.

That said, you’ll consume reduced energy and won’t have to change your air filter as frequently. Both are savings that can tally up over the year, so you’ll have to consider what’s best for your home.
