Which Takes 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 charge. So, it’s given that you’re seeking ways to consume less energy. That can entail finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cold air it creates. You control this fan at your thermostat by switching it to “auto,” which indicates the fan will only run when the air conditioner is running. Or you can set it to “on,” which signifies it will be on constantly.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better stabilize your family’s comfort. This is great if you have a two-story residence, since spaces upstairs can be hotter. It’s also good if you have problems with uneven cooling on account of hot and cold areas.

It’s also great if someone in your household deals with allergies, asthma or other respiratory symptoms. That’s since the air is consistently being distributed and filtrated. On the other hand, you may have to replace your air filters more often.

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

Your home may also appear more humid. Air conditioning helps manage humidity by extracting wetness from the air. But if the fan is continuously on, it’s more difficult for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only work when your air conditioner does. It’s ideal if your residence always feels comfortable, whichever room you’re in.

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

That said, you’ll consume reduced energy and won’t be required to get a new air filter as frequently. Both are savings that can tally up over the year, so you’ll have to consider what’s right for your needs.
