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

July 16, 2020

During the summer, using your air conditioning can be your highest monthly electrical expense. So, it’s given that you’re checking for approaches to consume less energy. That could involve trying 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 spend less money.

Your air conditioner uses a fan to deliver the cold air it creates. You manage this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is operating. Or you can set it to “on,” which indicates it will be on constantly.

Does putting your AC on “fan” save energy in Hattiesburg? This isn’t always the case. Generally, running your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also has a few pluses (and drawbacks) in regard to your residence’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 own a two-story residence, since spaces upstairs can be hotter. It’s also good if you have problems with unbalanced cooling because of hot and cold areas.

It’s also advantageous if one of your loved ones suffers from allergies, asthma or other respiratory symptoms. That’s because the air is continuously being distributed and filtrated. However, you may have to replace your air filters more regularly.

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

Your home may also feel more moist. Air conditioning helps control humidity by extracting water from the air. But if the fan is continually going, 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 operate when your air conditioner does. It’s ideal if your home always appears cool, whichever area you’re in.

There are a few disadvantages to using the auto setting. You might have hot and cold locations in your house and lower air quality. This is since air isn’t always being distributed or being repeatedly filtered.

On the other hand, you’ll need a lower amount of energy and won’t have to change your air filter as regularly. Both are savings that can add up throughout the year, so you’ll have to think about what’s right for your family.
