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

July 16, 2020

During the high temperatures, running your air conditioning can be your highest monthly electrical charge. So, it’s normal that you’re looking for methods to consume less energy. That could include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model through air conditioner installation.

Switching your air conditioning’s fan setting is another way you can spend less money.

Your air conditioner works with a fan to deliver the cold air it makes. You adjust this fan at your thermostat by switching it to “auto,” which indicates the fan will only work when the air conditioner is running. Or you can adjust it to “on,” which means it will run all the time.

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

But it also has a few pluses (and disadvantages) as far as your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better equalize your family’s comfort. This is great if you have a two-story home, since rooms upstairs can be hotter. It’s also ideal if you have issues with uneven cooling because of hot and cold rooms.

It’s also great if someone in your household has allergies, asthma or other respiratory symptoms. That’s because the air is consistently being distributed and filtered. However, you may have to switch your air filters more often.

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 muggier. Air conditioning helps balance humidity by drawing water from the air. But if the fan is constantly going, it’s more difficult for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only operate when your air conditioner does. It’s ideal if your home always seems pleasant, regardless of which spot you’re in.

There are a few drawbacks to using the auto setting. You might have hot and cold areas in your house and lower air quality. This is due to the fact air isn’t always flowing or being constantly purified.

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