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

July 16, 2020

During the summer, operating your air conditioning can be your largest monthly electrical charge. So, it’s normal that you’re seeking ways to use less energy. That might entail using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system during air conditioner installation.

Changing your air conditioning’s fan setting is an additional way you can conserve money.

Your air conditioner relies on a fan to deliver the cool air it makes. You control this fan at your thermostat by switching it to “auto,” which indicates the fan will only be on when the air conditioner is operating. Or you can adjust it to “on,” which means it will be on constantly.

Does putting your AC on “fan” save energy in Jefferson City? Not necessarily. Usually, running your air conditioner’s fan constantly is going to increase your energy bill slightly.

But it also offers a few advantages (and drawbacks) in relation to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better equalize your home’s comfort. This is great if you have a two-story house, since areas upstairs can be more hot. It’s also great if you have difficulties with unbalanced cooling because of hot and cold spaces.

It’s also beneficial if someone in your household has been diagnosed with allergies, asthma or other respiratory symptoms. That’s since the air is consistently being circulated and purified. However, you may have to switch your air filters more often.

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

Your home may also seem muggier. Air conditioning helps manage humidity by clearing water from the air. But if the fan is continuously running, it’s harder for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only operate when your air conditioner does. It’s ideal if your house always feels the right temperature, whichever spot you’re in.

There are a few drawbacks to using the auto setting. You could have hot and cold locations in your home and reduced air quality. This is because air isn’t continuously flowing or being repeatedly filtrated.

That said, you’ll require reduced energy and won’t have to switch you air filter as often. Both are savings that can build up throughout the year, so you’ll have to think over what’s ideal for your household.
