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

July 16, 2020

During the summer, using your air conditioning can be your highest monthly electrical cost. So, it’s given that you’re checking for methods to consume less energy. That can entail using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model through air conditioner installation.

Modifying your air conditioning’s fan setting is another way you can save money.

Your air conditioner relies on a fan to distribute the cool air it produces. You adjust this fan at your thermostat by switching it to “auto,” which indicates the fan will only work when the air conditioner is running. Or you can set it to “on,” which means it will be on all the time.

Does putting your AC on “fan” save energy in Logan? Not always. Usually, operating your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also provides a few perks (and drawbacks) in relation to your family’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 own a two-story house, since spaces upstairs can be warmer. It’s also good if you struggle with uneven cooling due to hot and cold areas.

It’s also beneficial if someone in your household has been diagnosed with allergies, asthma or other respiratory issues. That’s since the air is constantly being dispersed and purified. However, you may have to change your air filters more frequently.

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

Your home may also feel muggier. Air conditioning helps manage humidity by clearing moisture from the air. But if the fan is continually running, it’s challenging for moisture to drain from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only work when your air conditioner does. It’s good if your residence always appears comfy, whichever spot you’re in.

There are a few downsides to using the auto setting. You could run into hot and cold locations in your house and decreased air quality. This is due to the fact air isn’t always being distributed or being repeatedly purified.

On the other hand, you’ll consume less energy and won’t have to change your air filter as regularly. Both are savings that can add up over the year, so you’ll have to think over what’s best for your family.
