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

July 16, 2020

During the high temperatures, operating your air conditioning can be your largest monthly electricity expense. So, it’s normal that you’re looking for methods to consume less energy. That could involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner works with a fan to deliver the chilled air it creates. You control this fan at your thermostat by setting it to “auto,” which means the fan will only work when the air conditioner is operating. Or you can set it to “on,” which means it will work continuously.

Does putting your AC on “fan” save energy in Boynton Beach? Not always. Usually, operating your air conditioner’s fan all the time is going to make your energy bill slightly higher.

But it also has a few pluses (and downsides) when it comes to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better stabilize your home’s comfort. This is ideal if you live in a two-story residence, since areas upstairs can be warmer. It’s also good if you struggle with inconsistent cooling on account of hot and cold areas.

It’s also good if one of your family members has been diagnosed with allergies, asthma or other respiratory symptoms. That’s since the air is constantly being distributed and filtrated. On the flip side, you may have to put in new air filters more regularly.

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

Your residence may also seem muggier. Air conditioning helps balance humidity by extracting moisture from the air. But if the fan is constantly going, it’s challenging for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only work when your air conditioner does. It’s good if your residence always seems comfy, no matter what spot you’re in.

There are a few disadvantages to using the auto setting. You may run into hot and cold spots in your home and decreased air quality. This is due to the fact air isn’t constantly moving or being constantly filtered.

On the other hand, you’ll use a lower amount of energy and won’t have to change your air filter as often. Both are savings that can add up during the year, so you’ll have to consider what’s right for your home.
