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

July 16, 2020

During the hot weather, operating your air conditioning can be your biggest monthly electricity charge. So, it’s given that you’re checking for ways to consume less energy. That might include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system through air conditioner installation.

Regulating your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner relies on a fan to distribute the cold air it creates. You manage this fan at your thermostat by switching it to “auto,” which means the fan will only be on when the air conditioner is operating. Or you can set it to “on,” which indicates it will operate continuously.

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

But it also provides a few advantages (and drawbacks) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all the time can better stabilize your family’s comfort. This is great if you have a two-story house, since rooms upstairs can be more hot. It’s also great if you have issues with unbalanced cooling on account of hot and cold spaces.

It’s also good if one of your family members deals with allergies, asthma or other respiratory issues. That’s due to the fact the air is constantly being dispersed and filtered. However, you may have to install new air filters more regularly.

Having the fan on all the time can also increase your energy bills. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your house may also seem more moist. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is constantly working, it’s challenging for moisture to drain from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only work when your air conditioner does. It’s good if your house always appears the right temperature, no matter what room you’re in.

There are a few drawbacks to using the auto setting. You might have hot and cold spots in your home and reduced air quality. This is due to the fact air isn’t always flowing or being repeatedly filtered.

On the flip side, you’ll consume a lower amount of energy and won’t need to change your air filter as frequently. Both are savings that can add up over the year, so you’ll have to consider what’s ideal for your family.
