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

During the summer, using your air conditioning can be your highest monthly utility cost. So, it’s only natural that you’re looking for methods to consume less energy. 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 an additional way you can conserve money.

Your air conditioner uses a fan to distribute the cold air it creates. You adjust this fan at your thermostat by setting it to “auto,” which means the fan will only work when the air conditioner is cooling. 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 South Beloit and Belvidere? Not necessarily. Generally, operating your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also provides a few pluses (and disadvantages) when it comes to your residence’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 good if you have a two-story house, since spaces upstairs can be more hot. It’s also good if you have issues with uneven cooling because of hot and cold spots.

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 consistently being distributed and filtered. However, you may have to switch your air filters more frequently.

Having the fan on all day can also make your energy bills more expensive. It could also cause the fan to wear out more quickly and need air conditioning repair.

Your house may also feel more moist. Air conditioning helps control humidity by removing water from the air. But if the fan is constantly running, it’s harder for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only run when your air conditioner does. It’s ideal if your home always feels pleasant, no matter what room you’re in.

There are a few drawbacks to using the auto setting. You may run into hot and cold areas in your home and lower air quality. This is since air isn’t constantly being distributed or being continuously filtrated.

On the flip side, you’ll consume a lower amount of energy and won’t need to change your air filter as regularly. Both are savings that can build up throughout the year, so you’ll have to consider what’s right for your home.
