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

July 16, 2020

During the high temperatures, using your air conditioning can be your highest monthly electrical cost. So, it’s given that you’re seeking approaches to save. That might include using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system during air conditioner installation.

Regulating your air conditioning’s fan setting is a second way you can save money.

Your air conditioner uses a fan to distribute the cold air it creates. You manage 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 signifies it will operate continuously.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better equalize your family’s comfort. This is ideal if you live in a two-story home, since rooms upstairs can be more hot. It’s also good if you struggle with unbalanced cooling because of hot and cold rooms.

It’s also advantageous if one of your family members suffers from allergies, asthma or other respiratory illnesses. That’s because the air is consistently being distributed and purified. However, you may have to install new air filters more often.

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

Your residence may also seem more humid. Air conditioning helps balance humidity by removing water from the air. But if the fan is constantly running, it’s harder for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only go when your air conditioner does. It’s good if your residence always feels comfy, no matter what spot you’re in.

There are a few disadvantages to using the auto setting. You may have hot and cold spots in your house and reduced air quality. This is due to the fact air isn’t continuously being distributed or being continuously filtrated.

That said, you’ll require a lower amount of energy and won’t be required to get a new air filter as regularly. Both are savings that can add up during the year, so you’ll have to think over what’s ideal for your family.
