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

July 16, 2020

During the high temperatures, operating your air conditioning can be your biggest monthly electrical charge. So, it’s given that you’re checking for methods to save. That may include using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cool air it makes. You adjust this fan at your thermostat by switching it to “auto,” which means the fan will only run when the air conditioner is working. Or you can set it to “on,” which indicates it will run constantly.

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

But it also offers a few pluses (and drawbacks) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better equalize your house’s comfort. This is great if you live in a two-story home, since spaces upstairs can be more hot. It’s also good if you have issues with inconsistent cooling because of hot and cold areas.

It’s also good if one of your family members deals with allergies, asthma or other respiratory problems. That’s since the air is consistently being distributed and purified. However, you may have to replace your air filters more frequently.

Having the fan on constantly can also drive up your energy bills. It could also cause the fan to wear out faster and need air conditioning repair.

Your house may also feel muggier. Air conditioning helps manage humidity by extracting water from the air. But if the fan is constantly running, it’s more difficult for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only run when your air conditioner does. It’s ideal if your residence always appears the right temperature, regardless of which area you’re in.

There are a few drawbacks to using the auto setting. You could run into hot and cold spots in your residence and lower air quality. This is since air isn’t continuously being distributed or being repeatedly purified.

On the other hand, you’ll consume reduced energy and won’t need to get a new air filter as frequently. Both are savings that can tally up during the year, so you’ll have to think over what’s right for your home.
