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

July 16, 2020

During the summer, running your air conditioning can be your biggest monthly electricity expense. So, it’s normal that you’re seeking methods to save. That may entail using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner uses a fan to deliver the chilled air it creates. You manage this fan at your thermostat by changing it to “auto,” which indicates the fan will only work when the air conditioner is running. Or you can set it to “on,” which signifies it will operate continuously.

Does putting your AC on “fan” save energy in Dayton? This isn’t always the case. Typically, using 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 disadvantages) in regard to your family’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 family’s comfort. This is ideal if you have a two-story house, since spaces upstairs can be hotter. It’s also ideal if you have issues with uneven cooling on account of hot and cold areas.

It’s also great if one of your loved ones deals with allergies, asthma or other respiratory symptoms. That’s since the air is continuously being distributed and purified. On the flip side, you may have to put in new air filters more frequently.

Having the fan on all the time can also make your energy bills more expensive. It could also result in the fan wearing out faster and need air conditioning repair.

Your home may also feel muggier. Air conditioning helps balance humidity by extracting moisture from the air. But if the fan is continuously going, it’s harder for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

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

There are a few downsides to using the auto setting. You might have hot and cold spots in your home and reduced air quality. This is because air isn’t continuously moving or being constantly filtrated.

On the flip side, you’ll consume reduced energy and won’t need to replace your air filter as often. Both are savings that can build up throughout the year, so you’ll have to think over what’s best for your household.
