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

July 16, 2020

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

Adjusting your air conditioning’s fan setting is another way you can spend less money.

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

Does putting your AC on “fan” save energy in Lawrence? Not always. Typically, using your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also has a few perks (and drawbacks) as far as your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better balance your family’s comfort. This is good if you have a two-story house, since spaces upstairs can be more hot. It’s also great if you have issues with inconsistent cooling due to hot and cold areas.

It’s also great if someone in your household has allergies, asthma or other respiratory illnesses. That’s since the air is continuously being distributed and filtrated. However, you may have to change your air filters more regularly.

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

Your residence may also feel muggier. Air conditioning helps manage humidity by removing moisture from the air. But if the fan is continually on, it’s harder for moisture to flow from the condenser outside.

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 ideal if your home always appears pleasant, whichever area you’re in.

There are a few downsides to using the auto setting. You could experience hot and cold locations in your home and lower air quality. This is because air isn’t constantly being distributed or being repeatedly filtrated.

That said, you’ll need less energy and won’t have to change your air filter as regularly. Both are savings that can build up during the year, so you’ll have to think over what’s right for your home.
