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

July 16, 2020

During the hot weather, running your air conditioning can be your biggest monthly electricity expense. So, it’s only natural that you’re seeking approaches to consume less energy. That may involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit with air conditioner installation.

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

Your air conditioner uses a fan to dispatch the chilled air it makes. You control this fan at your thermostat by setting it to “auto,” which signifies the fan will only work when the air conditioner is running. Or you can switch it to “on,” which means it will work continuously.

Does putting your AC on “fan” save energy in Kutztown? Not always. Typically, operating your air conditioner’s fan constantly is going to increase your energy bill slightly.

But it also offers a few pluses (and drawbacks) in relation to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better balance your house’s comfort. This is great if you own a two-story house, since areas upstairs can be warmer. It’s also great if you have problems with unbalanced cooling on account of hot and cold areas.

It’s also advantageous if one of your loved ones has allergies, asthma or other respiratory issues. That’s because the air is continuously being circulated and purified. On the other hand, you may have to put in new air filters more regularly.

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

Your home may also feel more moist. Air conditioning helps balance humidity by extracting moisture from the air. But if the fan is continuously working, it’s more difficult for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only operate when your air conditioner does. It’s good if your house always appears comfortable, whichever room you’re in.

There are a few disadvantages to using the auto setting. You might experience hot and cold spots in your residence and reduced air quality. This is due to the fact air isn’t always being distributed or being repeatedly filtrated.

On the other hand, you’ll need a lower amount of energy and won’t have to change your air filter as frequently. Both are savings that can add up throughout the year, so you’ll have to think over what’s ideal for your family.
