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

During the hot weather, operating your air conditioning can be your biggest monthly electrical charge. So, it’s only natural that you’re looking for ways to save. That might involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit through air conditioner installation.

Changing your air conditioning’s fan setting is a second way you can save money.

Your air conditioner works with a fan to dispatch the cool air it creates. You adjust 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 Lexington? Not necessarily. Usually, using your air conditioner’s fan constantly is going to increase your energy bill slightly.

But it also has a few pluses (and downsides) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better balance your family’s comfort. This is ideal if you own a two-story home, since areas upstairs can be warmer. It’s also good if you have issues with unbalanced cooling because of hot and cold spaces.

It’s also advantageous if someone in your household deals with allergies, asthma or other respiratory symptoms. That’s since the air is constantly being circulated and filtered. On the flip side, you may have to replace your air filters more regularly.

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

Your residence may also seem more humid. Air conditioning helps balance humidity by drawing wetness from the air. But if the fan is continuously running, it’s challenging for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

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

There are a few disadvantages to using the auto setting. You might run into hot and cold spots in your home and reduced air quality. This is since air isn’t continuously flowing or being constantly purified.

That said, you’ll use reduced energy and won’t need to get a new air filter as often. Both are savings that can build up over the year, so you’ll have to think over what’s best for your needs.
