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

July 16, 2020

During the summer, running your air conditioning can be your largest monthly electricity expense. So, it’s given that you’re looking for ways to save. That could involve trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model with air conditioner installation.

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

Your air conditioner uses a fan to distribute the cool air it creates. You adjust this fan at your thermostat by setting it to “auto,” which indicates the fan will only be on when the air conditioner is running. Or you can adjust it to “on,” which indicates it will be on all the time.

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

But it also provides 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 run all the time can better balance your family’s comfort. This is ideal if you live in a two-story house, since areas upstairs can be more hot. It’s also ideal if you struggle with uneven cooling because of hot and cold areas.

It’s also advantageous if someone in your household has been diagnosed with allergies, asthma or other respiratory symptoms. That’s due to the fact the air is consistently being distributed and filtrated. On the flip side, you may have to put in new air filters more regularly.

Having the fan on all the time can also increase your energy bills. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your house may also seem more moist. Air conditioning helps control humidity by clearing 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 work when your air conditioner does. It’s great if your house always feels the right temperature, no matter what room you’re in.

There are a few drawbacks to using the auto setting. You may have hot and cold spots in your home and lower air quality. This is due to the fact air isn’t continuously moving or being repeatedly filtrated.

That said, you’ll consume less energy and won’t be required to change your air filter as frequently. Both are savings that can tally up during the year, so you’ll have to think over what’s ideal for your home.
