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

July 16, 2020

During the summer, running your air conditioning can be your largest monthly utility expense. So, it’s only natural that you’re seeking ways to use less energy. That could involve finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model through air conditioner installation.

Switching your air conditioning’s fan setting is an additional way you can conserve money.

Your air conditioner uses a fan to distribute the chilled air it produces. You control this fan at your thermostat by setting it to “auto,” which means the fan will only run when the air conditioner is running. Or you can adjust it to “on,” which means it will be on continuously.

Does putting your AC on “fan” save energy in Laguna Niguel? Not always. Usually, using your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also has a few pluses (and drawbacks) in relation to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better equalize your house’s comfort. This is great if you own a two-story residence, since areas upstairs can be more hot. It’s also ideal if you have issues with uneven cooling due to hot and cold spots.

It’s also great if one of your family members has allergies, asthma or other respiratory issues. That’s since the air is continuously being circulated and filtrated. However, you may have to put in new air filters more often.

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

Your house may also seem more moist. Air conditioning helps manage humidity by removing wetness 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 highest energy-efficient setting, because the fan will only go when your air conditioner does. It’s great if your house always appears comfortable, no matter what area you’re in.

There are a few disadvantages to using the auto setting. You might experience hot and cold areas in your residence and lower air quality. This is since air isn’t always flowing or being constantly purified.

That said, you’ll consume less energy and won’t have to get a new air filter as regularly. Both are savings that can build up over the year, so you’ll have to consider what’s best for your home.
