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

July 16, 2020

During the summer, running your air conditioning can be your largest monthly electrical expense. So, it’s given that you’re seeking ways to use less energy. That can include trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit through air conditioner installation.

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

Your air conditioner relies on a fan to dispatch the cold air it creates. You manage this fan at your thermostat by changing it to “auto,” which signifies the fan will only work when the air conditioner is operating. Or you can adjust it to “on,” which means it will run continuously.

Does putting your AC on “fan” save energy in Kearney? This isn’t always the case. Generally, running your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also provides a few advantages (and downsides) as far as your home’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 good if you own a two-story home, since spaces upstairs can be hotter. It’s also great if you have difficulties with uneven cooling on account of hot and cold spots.

It’s also advantageous if one of your family members has been diagnosed with allergies, asthma or other respiratory symptoms. That’s because the air is consistently being circulated and purified. On the other hand, you may have to switch your air filters more regularly.

Having the fan on constantly can also increase your energy bills. It could also make the fan wear out sooner and need air conditioning repair.

Your home may also appear more humid. Air conditioning helps manage humidity by removing moisture from the air. But if the fan is always running, it’s harder for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only run when your air conditioner does. It’s ideal if your residence always appears the right temperature, regardless of which area you’re in.

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

That said, you’ll need a lower amount of energy and won’t need to get a new air filter as regularly. Both are savings that can add up during the year, so you’ll have to think over what’s best for your family.
