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

July 16, 2020

During the hot weather, operating your air conditioning can be your largest monthly utility expense. So, it’s given that you’re checking for methods to save. That might involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

Modifying your air conditioning’s fan setting is another way you can save money.

Your air conditioner works with a fan to deliver the cool air it produces. You control this fan at your thermostat by switching it to “auto,” which signifies the fan will only run when the air conditioner is running. Or you can set it to “on,” which means it will be on constantly.

Does putting your AC on “fan” save energy in Keokuk? Not always. Generally, operating your air conditioner’s fan all the time is going to increase your energy bill slightly.

But it also gives a few advantages (and downsides) in relation to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

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

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

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 house may also appear more humid. Air conditioning helps manage humidity by removing moisture from the air. But if the fan is continuously running, it’s more difficult for moisture to drain from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only run when your air conditioner does. It’s good 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 reduced air quality. This is because air isn’t constantly being distributed or being repeatedly filtered.

On the other hand, you’ll consume less energy and won’t need to get a new air filter as regularly. Both are savings that can build up throughout the year, so you’ll have to think about what’s ideal for your household.
