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

July 16, 2020

During the high temperatures, running your air conditioning can be your largest monthly utility expense. So, it’s normal that you’re seeking methods to use less energy. That can involve finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner works with a fan to dispatch the chilled air it makes. You manage this fan at your thermostat by switching it to “auto,” which indicates the fan will only run 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 Long Island? Not always. Usually, operating your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also offers a few perks (and disadvantages) as far as your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better stabilize your home’s comfort. This is great if you own a two-story residence, since rooms upstairs can be more hot. It’s also great if you have problems with inconsistent cooling due to hot and cold spots.

It’s also beneficial if someone in your household deals with allergies, asthma or other respiratory symptoms. That’s because the air is continuously being circulated and filtrated. On the flip side, you may have to replace your air filters more regularly.

Having the fan on all day can also drive up your energy bills. It could also result in the fan wearing out more quickly and need air conditioning repair.

Your residence may also appear muggier. Air conditioning helps manage humidity by removing wetness from the air. But if the fan is continually going, it’s challenging for moisture to drain from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only run when your air conditioner does. It’s good if your home always feels cool, no matter what spot you’re in.

There are a few drawbacks to using the auto setting. You could experience hot and cold locations in your home and decreased air quality. This is because air isn’t always being distributed or being constantly filtrated.

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