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

July 16, 2020

During the summer, operating your air conditioning can be your biggest monthly utility expense. So, it’s normal that you’re seeking ways to consume less energy. That may involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

Changing your air conditioning’s fan setting is another way you can save money.

Your air conditioner uses a fan to deliver the chilled air it produces. 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 switch it to “on,” which means it will run all the time.

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

But it also gives a few pluses (and downsides) when it comes 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 home’s comfort. This is good if you live in a two-story house, since areas upstairs can be hotter. It’s also good if you have difficulties with uneven cooling on account of hot and cold rooms.

It’s also beneficial if one of your loved ones has been diagnosed with allergies, asthma or other respiratory symptoms. That’s since the air is constantly being circulated and filtrated. However, you may have to put in new air filters more frequently.

Having the fan on all the time can also drive up your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

Your home may also seem more moist. Air conditioning helps control humidity by removing moisture from the air. But if the fan is continuously going, it’s harder for moisture to flow from the condenser externally.

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 home always appears the right temperature, no matter what spot you’re in.

There are a few downsides to using the auto setting. You could have hot and cold locations in your house and lower air quality. This is due to the fact air isn’t always being distributed or being repeatedly filtered.

On the other hand, you’ll use reduced energy and won’t be required to replace your air filter as frequently. Both are savings that can add up during the year, so you’ll have to consider what’s right for your household.
