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

During the high temperatures, running your air conditioning can be your largest monthly electricity cost. So, it’s only natural that you’re looking for methods to consume less energy. That could entail using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit through air conditioner installation.

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

Your air conditioner relies on a fan to dispatch the cold air it makes. You manage this fan at your thermostat by switching it to “auto,” which indicates the fan will only work when the air conditioner is running. Or you can set it to “on,” which signifies it will run all the time.

Does putting your AC on “fan” save energy in Alice? Not necessarily. Generally, using your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also has a few advantages (and disadvantages) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better balance your family’s comfort. This is good if you have a two-story residence, since spaces upstairs can be more hot. It’s also great if you have issues with uneven cooling due to hot and cold spaces.

It’s also great if one of your family members suffers from allergies, asthma or other respiratory illnesses. That’s since the air is continuously being dispersed and filtrated. However, you may have to install 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 home may also seem muggier. Air conditioning helps manage humidity by extracting moisture from the air. But if the fan is continually going, it’s challenging for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only operate when your air conditioner does. It’s great if your house always seems cool, no matter what room you’re in.

There are a few downsides to using the auto setting. You may have hot and cold spots in your residence and decreased air quality. This is since air isn’t always being distributed or being repeatedly filtrated.

On the other hand, you’ll need reduced energy and won’t need to replace your air filter as frequently. Both are savings that can build up over the year, so you’ll have to consider what’s right for your household.
