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

July 16, 2020

During the high temperatures, using your air conditioning can be your largest monthly electricity cost. So, it’s given that you’re looking for ways to save. That can entail finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner uses a fan to dispatch the cool air it produces. You manage this fan at your thermostat by switching it to “auto,” which indicates the fan will only run when the air conditioner is running. Or you can adjust it to “on,” which signifies it will be on constantly.

Does putting your AC on “fan” save energy in Rock Hill? This isn’t always the case. Generally, using your air conditioner’s fan constantly is going to increase your energy bill slightly.

But it also gives a few perks (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 operate continuously can better stabilize your house’s comfort. This is great if you live in a two-story home, since areas upstairs can be more hot. It’s also great if you have difficulties with unbalanced cooling because of hot and cold areas.

It’s also beneficial if someone in your household deals with allergies, asthma or other respiratory illnesses. That’s since the air is consistently being distributed and filtered. However, you may have to replace your air filters more often.

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

Your residence may also feel more moist. Air conditioning helps manage humidity by extracting water from the air. But if the fan is constantly going, it’s harder for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only operate when your air conditioner does. It’s ideal if your residence always appears cool, no matter what spot you’re in.

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

On the flip side, you’ll need less energy and won’t be required to replace your air filter as often. Both are savings that can build up during the year, so you’ll have to consider what’s right for your family.
