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

During the hot weather, using your air conditioning can be your largest monthly electricity expense. So, it’s normal that you’re looking for ways to save. That may involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model during air conditioner installation.

Regulating your air conditioning’s fan setting is an additional way you can conserve money.

Your air conditioner works with a fan to deliver the cold air it produces. You adjust 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 switch it to “on,” which means it will operate constantly.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better stabilize your home’s comfort. This is ideal if you live in a two-story house, since areas upstairs can be more hot. It’s also good if you have problems with uneven cooling on account of hot and cold spots.

It’s also advantageous if someone in your household has been diagnosed with allergies, asthma or other respiratory symptoms. That’s due to the fact the air is consistently being dispersed and filtered. However, you may have to put in new air filters more often.

Having the fan on all day can also make your energy bills more expensive. It could also result in the fan wearing out sooner and need air conditioning repair.

Your home may also seem muggier. Air conditioning helps manage humidity by removing water from the air. But if the fan is continuously working, it’s more difficult for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only go when your air conditioner does. It’s great if your house always feels cool, whichever spot you’re in.

There are a few downsides to using the auto setting. You might run into hot and cold locations in your home and reduced air quality. This is due to the fact air isn’t continuously moving or being continuously filtered.

That said, you’ll require less energy and won’t have to change your air filter as regularly. Both are savings that can tally up throughout the year, so you’ll have to consider what’s right for your family.
