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

During the hot weather, operating your air conditioning can be your highest monthly utility cost. So, it’s normal that you’re looking for ways to consume less energy. That could involve using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system during air conditioner installation.

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

Your air conditioner relies on a fan to deliver the chilled air it makes. You manage this fan at your thermostat by setting it to “auto,” which means the fan will only run when the air conditioner is going. Or you can switch it to “on,” which signifies it will run constantly.

Does putting your AC on “fan” save energy in Carpentersville? Not necessarily. Usually, using your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also gives a few advantages (and disadvantages) in regard 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 balance your house’s comfort. This is great if you have a two-story residence, since spaces upstairs can be warmer. It’s also good if you have problems with inconsistent cooling due to hot and cold areas.

It’s also great if someone in your household deals with allergies, asthma or other respiratory issues. That’s because the air is constantly being circulated and filtrated. However, you may have to install new air filters more regularly.

Having the fan on all day can also drive up your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

Your house may also appear muggier. Air conditioning helps balance humidity by removing wetness from the air. But if the fan is always running, it’s challenging for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only go when your air conditioner does. It’s ideal if your house always feels comfortable, whichever room you’re in.

There are a few drawbacks to using the auto setting. You could have hot and cold locations in your residence and lower air quality. This is since air isn’t always being distributed or being constantly purified.

On the other hand, you’ll use less energy and won’t need to switch you air filter as frequently. Both are savings that can tally up during the year, so you’ll have to think about what’s best for your needs.
