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

July 16, 2020

During the summer, using your air conditioning can be your biggest monthly electricity cost. So, it’s normal that you’re looking for ways to consume less energy. That could entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner works with a fan to distribute the cool air it makes. You manage this fan at your thermostat by setting it to “auto,” which means the fan will only work when the air conditioner is cooling. Or you can set it to “on,” which means it will be on constantly.

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

But it also offers a few perks (and drawbacks) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better balance your house’s comfort. This is great if you have a two-story house, since rooms upstairs can be more hot. It’s also good if you have issues with uneven cooling because of hot and cold rooms.

It’s also advantageous if one of your family members deals with allergies, asthma or other respiratory issues. That’s because the air is continuously being distributed and purified. However, you may have to put in 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 prematurely and need air conditioning repair.

Your residence may also appear muggier. Air conditioning helps manage humidity by removing water from the air. But if the fan is continually working, it’s more difficult for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only go when your air conditioner does. It’s ideal if your residence always appears cool, no matter what spot you’re in.

There are a few drawbacks to using the auto setting. You could experience hot and cold areas in your residence and decreased air quality. This is because air isn’t constantly flowing or being constantly purified.

On the other hand, you’ll use a lower amount of energy and won’t need to get a new air filter as regularly. Both are savings that can build up over the year, so you’ll have to think about what’s right for your home.
