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

July 16, 2020

During the summer, using your air conditioning can be your largest monthly electricity cost. So, it’s normal that you’re seeking ways to consume less energy. That might entail finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

Changing your air conditioning’s fan setting is another way you can conserve money.

Your air conditioner relies on a fan to distribute the chilled air it makes. You manage this fan at your thermostat by changing it to “auto,” which signifies the fan will only run when the air conditioner is running. Or you can switch it to “on,” which signifies it will operate all the time.

Does putting your AC on “fan” save energy in Long Beach? Not always. Generally, operating your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also gives a few advantages (and disadvantages) when it comes to your home’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 ideal if you own a two-story house, since areas upstairs can be warmer. It’s also good if you struggle with inconsistent cooling on account of hot and cold areas.

It’s also great if one of your loved ones suffers from allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being dispersed and filtrated. On the flip side, you may have to install new air filters more frequently.

Having the fan on all the time can also make your energy bills more expensive. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your home may also seem muggier. Air conditioning helps control humidity by clearing moisture from the air. But if the fan is continually on, it’s challenging for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only work when your air conditioner does. It’s great if your house always feels cool, no matter what area you’re in.

There are a few downsides to using the auto setting. You might experience hot and cold spots in your home and decreased air quality. This is since air isn’t always moving or being repeatedly filtrated.

On the other hand, you’ll use a lower amount of energy and won’t be required to replace your air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to consider what’s ideal for your needs.
