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

July 16, 2020

During the summer, using your air conditioning can be your biggest monthly utility cost. So, it’s given that you’re seeking ways to use less energy. That may include using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cool air it creates. You manage this fan at your thermostat by changing it to “auto,” which means the fan will only work when the air conditioner is running. Or you can set it to “on,” which indicates it will be on all the time.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better balance your house’s comfort. This is good if you own a two-story house, since areas upstairs can be more hot. It’s also good if you have problems with inconsistent cooling because of hot and cold rooms.

It’s also great if one of your loved ones has been diagnosed with allergies, asthma or other respiratory symptoms. That’s because the air is continuously being dispersed and filtered. On the other hand, you may have to put in new air filters more frequently.

Having the fan on all day can also make your energy bills more expensive. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your house may also feel more humid. Air conditioning helps control humidity by clearing water from the air. But if the fan is constantly working, it’s more difficult for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only work when your air conditioner does. It’s great if your residence always seems pleasant, no matter what room you’re in.

There are a few drawbacks to using the auto setting. You could run into hot and cold areas in your residence and reduced air quality. This is due to the fact air isn’t continuously moving or being repeatedly filtered.

On the other hand, you’ll use less energy and won’t need to change your air filter as often. Both are savings that can add up throughout the year, so you’ll have to think over what’s ideal for your needs.
