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

During the high temperatures, using your air conditioning can be your biggest monthly utility cost. So, it’s only natural that you’re checking for ways to save. That can entail trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner works with a fan to dispatch the chilled air it creates. You manage this fan at your thermostat by switching it to “auto,” which means the fan will only work when the air conditioner is working. Or you can adjust it to “on,” which means it will be on continuously.

Does putting your AC on “fan” save energy in Litchfield Park? This isn’t always the case. Usually, running your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also has a few pluses (and drawbacks) in regard to your home’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 live in a two-story house, since rooms upstairs can be hotter. It’s also great if you have difficulties with unbalanced cooling on account of hot and cold rooms.

It’s also great if one of your family members has allergies, asthma or other respiratory problems. That’s due to the fact the air is constantly being distributed and purified. On the other hand, you may have to replace your air filters more often.

Having the fan on all day can also drive up your energy bills. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your residence may also seem more moist. Air conditioning helps control humidity by drawing moisture from the air. But if the fan is continually working, it’s harder for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

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

There are a few drawbacks to using the auto setting. You could experience hot and cold spots in your home and lower air quality. This is since air isn’t constantly flowing or being repeatedly filtrated.

That said, you’ll consume less energy and won’t have to switch you air filter as regularly. Both are savings that can tally up throughout the year, so you’ll have to consider what’s best for your home.
