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

July 16, 2020

During the high temperatures, running your air conditioning can be your highest monthly electrical charge. So, it’s normal that you’re checking for ways to consume less energy. That can include using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model with air conditioner installation.

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

Your air conditioner relies on a fan to deliver the cold air it produces. You control this fan at your thermostat by switching it to “auto,” which signifies the fan will only run when the air conditioner is running. Or you can set it to “on,” which means it will operate constantly.

Does putting your AC on “fan” save energy in Pella? Not always. Usually, running your air conditioner’s fan all day is going to increase your energy bill slightly.

But it also gives a few advantages (and downsides) in relation to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better stabilize your house’s comfort. This is ideal if you live in a two-story house, since rooms upstairs can be warmer. It’s also ideal if you have problems with uneven cooling because of hot and cold spots.

It’s also advantageous if one of your loved ones suffers from allergies, asthma or other respiratory problems. That’s since the air is consistently being circulated and filtered. On the other hand, you may have to replace your air filters more frequently.

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

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

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 great if your house always feels pleasant, whichever area you’re in.

There are a few drawbacks to using the auto setting. You may run into hot and cold spots in your residence and decreased air quality. This is since air isn’t constantly being distributed or being constantly purified.

On the other hand, you’ll use reduced energy and won’t be required to switch you air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to think over what’s ideal for your home.
