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

During the summer, running your air conditioning can be your highest monthly electricity charge. So, it’s only natural that you’re checking for methods to consume less energy. That may include trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model during air conditioner installation.

Switching your air conditioning’s fan setting is a second way you can conserve 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 signifies the fan will only work when the air conditioner is running. Or you can adjust it to “on,” which signifies it will operate all the time.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better stabilize your house’s comfort. This is good if you live in a two-story residence, since rooms upstairs can be more hot. It’s also great if you have problems with inconsistent cooling because of hot and cold rooms.

It’s also good if one of your loved ones has been diagnosed with allergies, asthma or other respiratory illnesses. That’s because the air is continuously being dispersed and purified. On the other hand, you may have to install new air filters more frequently.

Having the fan on constantly can also make your energy bills more expensive. It could also cause the fan to wear out faster and need air conditioning repair.

Your house may also appear muggier. Air conditioning helps balance humidity by drawing wetness from the air. But if the fan is continuously running, it’s challenging for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only operate when your air conditioner does. It’s good if your residence always seems comfy, whichever room you’re in.

There are a few drawbacks to using the auto setting. You might run into hot and cold spots in your home and lower air quality. This is because air isn’t always being distributed or being continuously filtrated.

That said, you’ll need reduced energy and won’t be required to switch you air filter as regularly. Both are savings that can build up over the year, so you’ll have to think over what’s ideal for your home.
