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

July 16, 2020

During the summer, running your air conditioning can be your biggest monthly utility cost. So, it’s only natural that you’re looking for approaches to use less energy. That can include using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner relies on a fan to dispatch the chilled air it creates. You control this fan at your thermostat by switching it to “auto,” which signifies the fan will only work when the air conditioner is operating. Or you can set it to “on,” which means it will operate all the time.

Does putting your AC on “fan” save energy in Huntingburg? Not necessarily. Typically, using your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also has a few perks (and downsides) when it comes to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all the time can better stabilize your house’s comfort. This is good if you live in a two-story house, since spaces upstairs can be hotter. It’s also good if you have difficulties with unbalanced cooling because of hot and cold areas.

It’s also good if someone in your household has been diagnosed with allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being distributed and filtrated. However, you may have to replace your air filters more regularly.

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

Your house may also feel more moist. Air conditioning helps balance humidity by removing wetness from the air. But if the fan is always working, it’s challenging for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only go when your air conditioner does. It’s great if your house always appears comfy, regardless of which area you’re in.

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

On the flip side, you’ll need less energy and won’t need to get a new air filter as often. Both are savings that can tally up during the year, so you’ll have to think about what’s best for your household.
