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

July 16, 2020

During the hot weather, operating your air conditioning can be your biggest monthly electrical charge. So, it’s only natural that you’re checking for approaches to save. That may involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system during air conditioner installation.

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

Your air conditioner relies on a fan to dispatch the cold air it produces. You adjust this fan at your thermostat by switching it to “auto,” which means the fan will only run when the air conditioner is working. Or you can switch it to “on,” which signifies it will work constantly.

Does putting your AC on “fan” save energy in Huntsville? Not necessarily. Generally, running 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) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better equalize your family’s comfort. This is ideal if you live in a two-story house, since areas upstairs can be warmer. It’s also ideal if you have problems with inconsistent cooling on account of hot and cold rooms.

It’s also advantageous if someone in your household has allergies, asthma or other respiratory issues. That’s since the air is constantly being circulated and purified. On the other hand, you may have to put in new air filters more regularly.

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

Your house may also seem muggier. Air conditioning helps control humidity by clearing wetness from the air. But if the fan is constantly running, it’s more difficult for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only run when your air conditioner does. It’s good if your house always appears cool, whichever room you’re in.

There are a few downsides to using the auto setting. You may experience hot and cold locations in your residence and lower air quality. This is due to the fact air isn’t always flowing or being continuously filtrated.

On the other hand, you’ll consume a lower amount of energy and won’t have to replace your air filter as often. Both are savings that can tally up over the year, so you’ll have to think over what’s right for your home.
