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

During the high temperatures, running your air conditioning can be your biggest monthly utility expense. So, it’s given that you’re looking for ways to use less energy. That might involve using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit through air conditioner installation.

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

Your air conditioner uses a fan to deliver the chilled air it produces. You control this fan at your thermostat by switching it to “auto,” which indicates the fan will only work when the air conditioner is going. Or you can adjust it to “on,” which signifies it will be on constantly.

Does putting your AC on “fan” save energy in Lodi? Not necessarily. Typically, running your air conditioner’s fan all the time is going to make your energy bill slightly higher.

But it also provides a few perks (and drawbacks) in regard to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better equalize your family’s comfort. This is great if you own a two-story house, since spaces upstairs can be more hot. It’s also ideal if you struggle with uneven 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 problems. That’s due to the fact the air is consistently being dispersed and filtered. On the other hand, you may have to change your air filters more often.

Having the fan on all the time can also drive up your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

Your house may also appear more humid. Air conditioning helps balance humidity by extracting moisture from the air. But if the fan is constantly working, it’s more difficult for moisture to drain from the condenser outside.

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 good if your home always seems comfortable, whichever spot you’re in.

There are a few drawbacks to using the auto setting. You might run into hot and cold areas in your residence and decreased air quality. This is due to the fact air isn’t continuously being distributed or being constantly filtrated.

On the flip side, you’ll consume reduced energy and won’t have to switch you air filter as regularly. Both are savings that can add up during the year, so you’ll have to think over what’s best for your family.
