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

July 16, 2020

During the hot weather, operating your air conditioning can be your highest monthly utility cost. So, it’s normal that you’re looking for approaches to use less energy. That could entail finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model with air conditioner installation.

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

Your air conditioner uses a fan to dispatch the cold air it creates. You manage this fan at your thermostat by setting it to “auto,” which signifies the fan will only be on when the air conditioner is going. Or you can set it to “on,” which indicates it will be on constantly.

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

But it also offers a few advantages (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 day can better balance your house’s comfort. This is ideal if you live in a two-story home, since rooms upstairs can be warmer. It’s also good if you struggle with unbalanced cooling because of hot and cold spots.

It’s also great if one of your family members has allergies, asthma or other respiratory symptoms. That’s due to the fact the air is constantly being circulated and filtered. However, you may have to switch your 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 more quickly and need air conditioning repair.

Your residence may also appear more humid. Air conditioning helps control humidity by drawing wetness from the air. But if the fan is constantly running, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only go when your air conditioner does. It’s great if your residence always feels pleasant, regardless of which spot you’re in.

There are a few downsides to using the auto setting. You could experience hot and cold locations in your home and decreased air quality. This is because air isn’t continuously flowing or being repeatedly filtered.

On the other hand, you’ll need a lower amount of energy and won’t need to replace your air filter as often. Both are savings that can build up throughout the year, so you’ll have to consider what’s right for your family.
