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

July 16, 2020

During the summer, operating your air conditioning can be your highest monthly electrical cost. So, it’s only natural that you’re seeking approaches to use less energy. That can entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

Modifying your air conditioning’s fan setting is a second way you can spend less money.

Your air conditioner works with a fan to dispatch the cold air it makes. You adjust this fan at your thermostat by switching it to “auto,” which signifies the fan will only be on when the air conditioner is operating. Or you can switch it to “on,” which indicates it will work continuously.

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

But it also offers a few pluses (and disadvantages) when it comes to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better balance your family’s comfort. This is ideal if you have a two-story residence, since rooms upstairs can be more hot. It’s also good if you have difficulties with unbalanced cooling due to hot and cold areas.

It’s also great if one of your loved ones has allergies, asthma or other respiratory illnesses. That’s due to the fact the air is constantly being circulated and filtrated. However, you may have to put in new air filters more often.

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

Your residence may also feel more humid. Air conditioning helps control humidity by extracting wetness from the air. But if the fan is continually working, it’s challenging for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

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

There are a few downsides to using the auto setting. You may have hot and cold areas in your home and decreased air quality. This is because air isn’t always flowing or being constantly filtered.

That said, you’ll require reduced energy and won’t have to replace your air filter as regularly. Both are savings that can tally up during the year, so you’ll have to think over what’s right for your needs.
