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 utility charge. So, it’s given that you’re seeking ways to use less energy. That may include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system with air conditioner installation.

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

Your air conditioner uses a fan to deliver the chilled air it makes. You adjust this fan at your thermostat by changing it to “auto,” which indicates the fan will only be on when the air conditioner is working. Or you can set it to “on,” which signifies it will work constantly.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better stabilize your family’s comfort. This is good if you have a two-story house, since spaces upstairs can be more hot. It’s also good if you have difficulties with inconsistent cooling due to hot and cold spaces.

It’s also advantageous if someone in your household has allergies, asthma or other respiratory problems. That’s because the air is constantly being circulated and filtered. However, you may have to install new air filters more frequently.

Having the fan on all the time can also drive up your energy bills. It could also result in the fan wearing out more quickly and need air conditioning repair.

Your house may also seem more moist. Air conditioning helps control humidity by removing water from the air. But if the fan is always working, it’s challenging for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only work when your air conditioner does. It’s good if your house always seems pleasant, whichever spot you’re in.

There are a few disadvantages to using the auto setting. You might have hot and cold locations in your residence and reduced air quality. This is since air isn’t always being distributed or being continuously filtered.

On the flip side, you’ll consume reduced energy and won’t have to replace your air filter as regularly. Both are savings that can build up during the year, so you’ll have to consider what’s ideal for your home.
