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

July 16, 2020

During the summer, running your air conditioning can be your biggest monthly electrical expense. So, it’s only natural that you’re looking for methods to consume less energy. That may include trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model with air conditioner installation.

Switching your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner uses a fan to dispatch the cold air it creates. You manage this fan at your thermostat by setting it to “auto,” which means the fan will only work 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 New Castle? This isn’t always the case. Usually, using your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also offers a few advantages (and downsides) as far as your family’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 house, since areas upstairs can be warmer. It’s also great if you have problems with uneven cooling due to hot and cold rooms.

It’s also good if someone in your household has allergies, asthma or other respiratory illnesses. That’s since the air is consistently being circulated and filtered. On the flip side, you may have to put in new air filters more regularly.

Having the fan on all day can also increase your energy bills. It could also result in the fan wearing out sooner and need air conditioning repair.

Your house may also appear muggier. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is continually going, it’s harder for moisture to drain from the condenser outside.

Air Conditioner Fan Set to “Auto”

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

There are a few downsides to using the auto setting. You could run into hot and cold spots in your residence and reduced air quality. This is due to the fact air isn’t continuously being distributed or being repeatedly filtered.

That said, you’ll consume a lower amount of energy and won’t have to change your air filter as regularly. Both are savings that can add up throughout the year, so you’ll have to consider what’s right for your family.
