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

July 16, 2020

During the high temperatures, using your air conditioning can be your highest monthly utility cost. So, it’s given that you’re looking for approaches to consume less energy. That might entail trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

Adjusting your air conditioning’s fan setting is an additional way you can save money.

Your air conditioner relies on a fan to distribute the chilled air it makes. You manage this fan at your thermostat by changing it to “auto,” which signifies the fan will only run when the air conditioner is working. Or you can adjust it to “on,” which means it will work continuously.

Does putting your AC on “fan” save energy in Ballwin and St. Charles? Not necessarily. Generally, running your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also provides a few advantages (and drawbacks) in relation to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better stabilize your house’s comfort. This is ideal if you own a two-story house, since rooms upstairs can be more hot. It’s also great if you struggle with uneven cooling because of hot and cold spots.

It’s also advantageous if someone in your household has been diagnosed with allergies, asthma or other respiratory illnesses. That’s since the air is constantly being distributed and filtered. On the flip side, you may have to install new air filters more regularly.

Having the fan on all the time can also drive up your energy bills. It could also result in the fan wearing out more quickly and need air conditioning repair.

Your house may also seem muggier. Air conditioning helps balance humidity by clearing water from the air. But if the fan is continually working, it’s challenging for moisture to drain from the condenser outside.

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 the right temperature, whichever area you’re in.

There are a few drawbacks to using the auto setting. You may have hot and cold locations in your house and reduced air quality. This is since air isn’t continuously moving or being constantly filtered.

That said, you’ll consume reduced energy and won’t have to switch you air filter as often. Both are savings that can build up throughout the year, so you’ll have to consider what’s ideal for your family.
