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

During the summer, operating your air conditioning can be your highest monthly utility charge. So, it’s given that you’re seeking ways to use less energy. That might involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model during air conditioner installation.

Modifying your air conditioning’s fan setting is a second way you can conserve money.

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

Does putting your AC on “fan” save energy in Columbia? This isn’t always the case. Typically, running your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also offers a few advantages (and disadvantages) as far as your home’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 house’s comfort. This is ideal if you have a two-story home, since rooms upstairs can be hotter. It’s also great if you have difficulties with uneven cooling because of hot and cold areas.

It’s also good if one of your loved ones has allergies, asthma or other respiratory problems. That’s because the air is consistently being circulated and filtered. On the other hand, you may have to install new air filters more often.

Having the fan on all the time can also increase your energy bills. It could also cause the fan to wear out faster and need air conditioning repair.

Your residence may also seem more humid. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is continually going, it’s more difficult for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only work when your air conditioner does. It’s good if your home always seems pleasant, whichever spot you’re in.

There are a few downsides to using the auto setting. You could experience hot and cold locations in your house and reduced air quality. This is due to the fact air isn’t constantly moving or being repeatedly purified.

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