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

July 16, 2020

During the summer, operating your air conditioning can be your largest monthly utility expense. So, it’s only natural that you’re seeking methods to save. That could include using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner uses a fan to distribute the cold air it produces. You adjust this fan at your thermostat by changing it to “auto,” which means the fan will only run when the air conditioner is cooling. Or you can set it to “on,” which indicates it will run all the time.

Does putting your AC on “fan” save energy in Neptune City? This isn’t always the case. Generally, operating your air conditioner’s fan constantly is going to make your energy bill slightly higher.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all the time can better balance your house’s comfort. This is great if you live in a two-story residence, since spaces upstairs can be hotter. It’s also ideal if you struggle with unbalanced cooling on account of hot and cold areas.

It’s also advantageous if someone in your household has allergies, asthma or other respiratory issues. That’s since the air is constantly being circulated and purified. On the flip side, you may have to put in new air filters more often.

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

Your residence may also appear more humid. Air conditioning helps control humidity by drawing moisture from the air. But if the fan is always running, it’s challenging for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only work when your air conditioner does. It’s ideal if your home always appears comfortable, whichever room you’re in.

There are a few drawbacks to using the auto setting. You could have hot and cold locations in your home and decreased air quality. This is because air isn’t continuously being distributed or being constantly purified.

That said, you’ll need reduced energy and won’t need to replace your air filter as often. Both are savings that can build up throughout the year, so you’ll have to think about what’s ideal for your home.
