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

July 16, 2020

During the high temperatures, using your air conditioning can be your biggest monthly utility cost. So, it’s normal that you’re checking for ways to consume less energy. That could include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system during air conditioner installation.

Modifying your air conditioning’s fan setting is a second way you can spend less money.

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

Does putting your AC on “fan” save energy in Eastland? This isn’t always the case. Usually, operating your air conditioner’s fan all the time is going to make your energy bill slightly higher.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better balance your family’s comfort. This is good if you live in a two-story house, since rooms upstairs can be warmer. It’s also ideal if you have problems with unbalanced cooling because of hot and cold spaces.

It’s also advantageous if one of your family members deals with allergies, asthma or other respiratory illnesses. That’s due to the fact the air is consistently being circulated and purified. However, you may have to replace your air filters more often.

Having the fan on constantly can also drive up your energy bills. It could also result in the fan wearing out sooner and need air conditioning repair.

Your home may also appear more moist. Air conditioning helps manage humidity by removing water from the air. But if the fan is constantly working, it’s harder for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only go when your air conditioner does. It’s great if your home always seems comfortable, whichever spot you’re in.

There are a few downsides to using the auto setting. You might experience hot and cold locations in your house and reduced air quality. This is because air isn’t continuously moving or being repeatedly filtered.

On the other hand, you’ll require less energy and won’t have to get a new air filter as often. Both are savings that can add up during the year, so you’ll have to consider what’s right for your home.
