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

During the hot weather, running your air conditioning can be your highest monthly utility cost. So, it’s only natural that you’re checking for ways to consume less energy. That could include trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit with air conditioner installation.

Changing your air conditioning’s fan setting is another way you can save money.

Your air conditioner relies on a fan to deliver the cold air it creates. You adjust this fan at your thermostat by changing it to “auto,” which signifies the fan will only work when the air conditioner is going. Or you can adjust it to “on,” which signifies it will operate constantly.

Does putting your AC on “fan” save energy in Elmhurst? This isn’t always the case. Usually, using your air conditioner’s fan constantly is going to drive up your energy bill slightly.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better equalize your house’s comfort. This is ideal if you live in a two-story home, since areas upstairs can be hotter. It’s also ideal if you have difficulties with uneven cooling on account of hot and cold spaces.

It’s also good if someone in your household deals with allergies, asthma or other respiratory illnesses. That’s due to the fact the air is consistently being circulated and filtrated. On the flip side, you may have to change your air filters more frequently.

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

Your home may also feel more moist. Air conditioning helps manage humidity by clearing water from the air. But if the fan is continually working, it’s harder 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 work when your air conditioner does. It’s ideal if your house always feels comfortable, no matter what area you’re in.

There are a few disadvantages to using the auto setting. You may experience hot and cold spots in your residence and decreased air quality. This is because air isn’t constantly flowing or being continuously filtered.

That said, you’ll require reduced energy and won’t need to change your air filter as frequently. Both are savings that can build up over the year, so you’ll have to think about what’s right for your household.
