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

July 16, 2020

During the summer, running your air conditioning can be your biggest monthly utility expense. So, it’s only natural that you’re checking for approaches to consume less energy. That may entail using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

Regulating your air conditioning’s fan setting is an additional way you can save money.

Your air conditioner uses a fan to dispatch the chilled air it produces. You manage this fan at your thermostat by changing it to “auto,” which signifies the fan will only be on when the air conditioner is running. Or you can switch it to “on,” which signifies it will run continuously.

Does putting your AC on “fan” save energy in Excelsior Springs? Not necessarily. Usually, running your air conditioner’s fan all the time is going to make your energy bill slightly higher.

But it also provides a few advantages (and disadvantages) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better stabilize your home’s comfort. This is great if you own a two-story house, since areas upstairs can be warmer. It’s also ideal if you have issues with uneven cooling on account of hot and cold spots.

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

Having the fan on all the time can also make your energy bills more expensive. It could also cause the fan to wear out faster and need air conditioning repair.

Your residence may also appear more humid. Air conditioning helps control humidity by extracting water from the air. But if the fan is always going, it’s harder for moisture to drain from the condenser outside.

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 residence always feels pleasant, whichever room you’re in.

There are a few drawbacks to using the auto setting. You could have hot and cold areas in your house and reduced air quality. This is since air isn’t always flowing or being constantly filtrated.

On the flip side, you’ll use reduced energy and won’t have to switch you air filter as regularly. Both are savings that can build up over the year, so you’ll have to think about what’s right for your household.
