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

During the high temperatures, running your air conditioning can be your biggest monthly electricity expense. So, it’s normal that you’re seeking ways to consume less energy. That might involve using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit through air conditioner installation.

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

Your air conditioner relies on a fan to distribute the chilled air it produces. You control this fan at your thermostat by setting it to “auto,” which indicates the fan will only run when the air conditioner is working. Or you can set it to “on,” which signifies it will work all the time.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better stabilize your house’s comfort. This is great if you have a two-story house, since areas upstairs can be hotter. It’s also great if you have difficulties with uneven cooling because of hot and cold rooms.

It’s also great if someone in your household has been diagnosed with allergies, asthma or other respiratory symptoms. That’s due to the fact the air is continuously being circulated and filtrated. However, you may have to put in new air filters more regularly.

Having the fan on all the time 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 muggier. Air conditioning helps manage humidity by clearing water from the air. But if the fan is always running, it’s harder for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only go when your air conditioner does. It’s ideal if your home always appears the right temperature, regardless of which area you’re in.

There are a few disadvantages to using the auto setting. You could run into hot and cold areas in your house and reduced air quality. This is because air isn’t continuously moving or being constantly filtered.

On the other hand, you’ll consume a lower amount of energy and won’t be required to replace your air filter as frequently. Both are savings that can add up during the year, so you’ll have to think about what’s best for your household.
