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

July 16, 2020

During the summer, operating your air conditioning can be your highest monthly electrical charge. So, it’s normal that you’re seeking approaches to use less energy. That could include trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit through air conditioner installation.

Regulating your air conditioning’s fan setting is a second way you can spend less money.

Your air conditioner relies on a fan to deliver the chilled air it produces. You manage this fan at your thermostat by changing it to “auto,” which indicates the fan will only run when the air conditioner is working. 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 Marshfield? Not necessarily. Usually, running your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also provides a few advantages (and disadvantages) in relation to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all the time can better balance your home’s comfort. This is good if you live in a two-story home, since areas upstairs can be hotter. It’s also great if you have difficulties with unbalanced cooling because of hot and cold spots.

It’s also great if one of your loved ones has been diagnosed with allergies, asthma or other respiratory issues. That’s because the air is consistently being distributed and purified. On the other hand, you may have to replace your air filters more regularly.

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

Your home may also appear more moist. Air conditioning helps control humidity by removing wetness from the air. But if the fan is continuously going, it’s challenging for moisture to drip 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 great if your house always feels the right temperature, 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 reduced air quality. This is because air isn’t constantly flowing or being repeatedly filtrated.

On the other hand, you’ll consume reduced energy and won’t have to replace your air filter as frequently. Both are savings that can add up throughout the year, so you’ll have to think over what’s right for your needs.
