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

July 16, 2020

During the summer, running your air conditioning can be your largest monthly electrical cost. So, it’s given that you’re seeking methods to save. That can involve finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated system during air conditioner installation.

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

Your air conditioner relies on a fan to deliver the cool air it produces. You adjust this fan at your thermostat by setting it to “auto,” which means the fan will only be on when the air conditioner is cooling. Or you can adjust it to “on,” which indicates it will operate continuously.

Does putting your AC on “fan” save energy in Huffman? Not necessarily. Typically, operating your air conditioner’s fan constantly is going to increase your energy bill slightly.

But it also offers a few perks (and disadvantages) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better equalize your house’s comfort. This is good if you have a two-story home, since spaces upstairs can be warmer. It’s also ideal if you have difficulties with inconsistent cooling due to hot and cold rooms.

It’s also great if one of your loved ones suffers from allergies, asthma or other respiratory issues. That’s since the air is continuously being dispersed and filtrated. On the flip side, you may have to switch your air filters more frequently.

Having the fan on constantly can also increase your energy bills. It could also result in the fan wearing out more quickly and need air conditioning repair.

Your home may also feel more humid. Air conditioning helps manage humidity by removing wetness 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 best energy-efficient setting, as the fan will only go when your air conditioner does. It’s ideal if your house always appears comfortable, no matter what spot you’re in.

There are a few disadvantages to using the auto setting. You might experience hot and cold spots in your residence and lower air quality. This is due to the fact air isn’t constantly being distributed or being constantly filtered.

On the other hand, you’ll need less energy and won’t need to switch you air filter as often. Both are savings that can add up over the year, so you’ll have to think about what’s best for your home.
