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

July 16, 2020

During the hot weather, operating your air conditioning can be your highest monthly electricity cost. So, it’s normal that you’re looking for approaches to use less energy. That can entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model through air conditioner installation.

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

Your air conditioner uses a fan to distribute the cold air it creates. You adjust this fan at your thermostat by changing it to “auto,” which means the fan will only work when the air conditioner is operating. Or you can adjust it to “on,” which means it will work continuously.

Does putting your AC on “fan” save energy in West Valley City? This isn’t always the case. Typically, using your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also offers a few perks (and downsides) when it comes to 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 family’s comfort. This is ideal if you have a two-story home, since rooms upstairs can be more hot. It’s also great if you have issues with inconsistent cooling due to hot and cold areas.

It’s also beneficial if one of your family members has allergies, asthma or other respiratory problems. That’s since the air is consistently 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 drive up your energy bills. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your house may also appear muggier. Air conditioning helps balance humidity by removing moisture from the air. But if the fan is continually on, it’s harder for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only run when your air conditioner does. It’s great if your house always appears comfortable, regardless of which spot you’re in.

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

On the flip side, you’ll need a lower amount of energy and won’t need to change your air filter as often. Both are savings that can tally up during the year, so you’ll have to consider what’s right for your family.
