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

July 16, 2020

During the hot weather, using your air conditioning can be your highest monthly utility expense. So, it’s only natural that you’re checking for approaches to use less energy. That can entail using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model during air conditioner installation.

Changing your air conditioning’s fan setting is a second way you can conserve money.

Your air conditioner relies on a fan to distribute the cold air it produces. You manage this fan at your thermostat by switching it to “auto,” which means the fan will only work when the air conditioner is running. Or you can adjust it to “on,” which indicates it will run continuously.

Does putting your AC on “fan” save energy in Cedar Rapids? Not always. Typically, operating your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also has a few pluses (and downsides) 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 balance your house’s comfort. This is good if you own a two-story residence, since rooms upstairs can be warmer. It’s also ideal if you have problems with uneven cooling on account of hot and cold spaces.

It’s also great if one of your loved ones deals with allergies, asthma or other respiratory problems. That’s because the air is consistently being circulated and filtrated. However, you may have to put in new air filters more regularly.

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

Your residence may also appear muggier. Air conditioning helps control humidity by removing moisture from the air. But if the fan is continuously on, it’s challenging for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only run when your air conditioner does. It’s ideal if your home always feels pleasant, regardless of which room you’re in.

There are a few disadvantages to using the auto setting. You might run into hot and cold areas in your home and decreased air quality. This is because air isn’t constantly moving or being continuously filtrated.

On the other hand, you’ll use reduced energy and won’t need to replace your air filter as often. Both are savings that can tally up over the year, so you’ll have to think about what’s best for your home.
