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

July 16, 2020

During the hot weather, using your air conditioning can be your biggest monthly utility cost. So, it’s given that you’re looking for methods to save. That may include using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model with 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 dispatch the chilled air it creates. You adjust this fan at your thermostat by switching it to “auto,” which signifies the fan will only work when the air conditioner is operating. Or you can switch it to “on,” which signifies it will operate continuously.

Does putting your AC on “fan” save energy in Tuscaloosa? Not always. Generally, running your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also provides a few pluses (and downsides) when it comes to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better equalize your home’s comfort. This is great if you live in a two-story house, since areas upstairs can be more hot. It’s also ideal if you have issues with uneven cooling because of hot and cold rooms.

It’s also great if one of your family members suffers from allergies, asthma or other respiratory illnesses. That’s due to the fact the air is continuously being distributed and purified. However, you may have to change your air filters more often.

Having the fan on constantly can also increase your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

Your house may also appear more moist. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is continually working, it’s more difficult for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only run when your air conditioner does. It’s ideal if your residence always appears comfy, whichever spot you’re in.

There are a few drawbacks to using the auto setting. You may have hot and cold spots in your home and decreased air quality. This is because air isn’t always moving or being continuously filtered.

On the flip side, you’ll need a lower amount of energy and won’t need to get a new air filter as frequently. Both are savings that can build up throughout the year, so you’ll have to think over what’s right for your needs.
