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

July 16, 2020

During the high temperatures, operating your air conditioning can be your largest monthly utility charge. So, it’s normal that you’re seeking methods to consume less energy. That can involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model through 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 dispatch the chilled air it makes. You adjust this fan at your thermostat by setting it to “auto,” which means the fan will only be on when the air conditioner is working. Or you can switch it to “on,” which indicates it will run all the time.

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

But it also offers a few pluses (and downsides) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all the time can better stabilize your house’s comfort. This is ideal if you live in a two-story residence, since spaces upstairs can be more hot. It’s also good if you have issues with uneven cooling on account of hot and cold rooms.

It’s also beneficial if one of your loved ones deals with allergies, asthma or other respiratory issues. That’s since the air is constantly being circulated and filtrated. On the flip side, you may have to replace your air filters more often.

Having the fan on constantly can also increase your energy bills. It could also cause the fan to wear out more quickly and need air conditioning repair.

Your residence may also feel muggier. Air conditioning helps manage humidity by clearing wetness from the air. But if the fan is constantly working, it’s harder for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only operate when your air conditioner does. It’s ideal if your residence always appears cool, no matter what room you’re in.

There are a few downsides to using the auto setting. You may have hot and cold locations in your house and decreased air quality. This is because air isn’t constantly being distributed or being continuously filtrated.

That said, you’ll consume less energy and won’t have to get a new air filter as often. Both are savings that can build up during the year, so you’ll have to think about what’s ideal for your home.
