Which Takes 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 cost. So, it’s given that you’re seeking methods to save. That could involve using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner uses a fan to deliver the cool air it makes. You manage this fan at your thermostat by changing it to “auto,” which signifies the fan will only run when the air conditioner is operating. Or you can switch it to “on,” which indicates it will be on all the time.

Does putting your AC on “fan” save energy in Cambridge? This isn’t always the case. Generally, operating your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also provides a few perks (and disadvantages) in regard 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 good if you have a two-story residence, since rooms upstairs can be warmer. It’s also great if you have problems with inconsistent cooling because of hot and cold rooms.

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 continuously being circulated and filtrated. On the flip side, 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 prematurely and need air conditioning repair.

Your house may also seem more humid. Air conditioning helps manage humidity by extracting wetness from the air. But if the fan is constantly going, it’s harder for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only work when your air conditioner does. It’s good if your home always appears comfy, no matter what area you’re in.

There are a few downsides to using the auto setting. You could run into hot and cold locations in your residence and reduced air quality. This is due to the fact air isn’t constantly flowing or being constantly filtrated.

On the flip side, you’ll require a lower amount of energy and won’t be required to replace your air filter as regularly. Both are savings that can tally up throughout the year, so you’ll have to think over what’s best for your family.
