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

July 16, 2020

During the hot weather, using your air conditioning can be your biggest monthly utility charge. So, it’s normal that you’re seeking methods to save. That may include using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated system with air conditioner installation.

Regulating your air conditioning’s fan setting is another way you can spend less money.

Your air conditioner relies on a fan to distribute the chilled air it makes. You control this fan at your thermostat by setting it to “auto,” which indicates the fan will only work when the air conditioner is operating. Or you can set it to “on,” which signifies it will be on continuously.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better equalize your house’s comfort. This is good if you own a two-story residence, since rooms upstairs can be warmer. It’s also great if you have problems with uneven cooling because of hot and cold spots.

It’s also advantageous if one of your family members has been diagnosed with allergies, asthma or other respiratory symptoms. That’s because the air is consistently being circulated and filtered. On the other hand, you may have to switch your air filters more frequently.

Having the fan on constantly can also make your energy bills more expensive. It could also result in the fan wearing out prematurely 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 continuously running, 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, as the fan will only work when your air conditioner does. It’s great if your residence always feels cool, no matter what spot you’re in.

There are a few drawbacks to using the auto setting. You might have hot and cold spots in your home and lower air quality. This is due to the fact air isn’t continuously flowing or being repeatedly filtrated.

That said, you’ll need less energy and won’t have to get a new air filter as frequently. Both are savings that can add up during the year, so you’ll have to think about what’s ideal for your household.
