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

July 16, 2020

During the hot weather, using your air conditioning can be your largest monthly electrical cost. So, it’s given that you’re seeking methods to consume less energy. That can involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner works with a fan to deliver the cool air it creates. You control this fan at your thermostat by changing it to “auto,” which means the fan will only be on when the air conditioner is operating. Or you can switch it to “on,” which indicates it will be on constantly.

Does putting your AC on “fan” save energy in Lincoln? Not necessarily. Usually, running your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also gives a few perks (and downsides) in relation to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better balance your family’s comfort. This is ideal if you have a two-story residence, since spaces upstairs can be hotter. It’s also good if you struggle with unbalanced cooling due to hot and cold rooms.

It’s also good if someone in your household suffers from allergies, asthma or other respiratory problems. That’s since the air is continuously being dispersed and filtrated. On the flip side, you may have to change your air filters more regularly.

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

Your residence may also appear more moist. Air conditioning helps manage humidity by removing moisture from the air. But if the fan is continuously running, it’s harder for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only go when your air conditioner does. It’s ideal if your home always feels comfortable, whichever spot you’re in.

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

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