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

July 16, 2020

During the high temperatures, running your air conditioning can be your largest monthly electricity charge. So, it’s only natural that you’re checking for approaches to save. That could involve finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

Modifying your air conditioning’s fan setting is a second way you can conserve money.

Your air conditioner relies on a fan to distribute the cool air it makes. You adjust this fan at your thermostat by setting it to “auto,” which signifies the fan will only work when the air conditioner is cooling. Or you can switch it to “on,” which indicates it will run continuously.

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

But it also offers a few advantages (and disadvantages) when it comes to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better equalize your home’s comfort. This is ideal if you own a two-story home, since areas upstairs can be more hot. It’s also ideal if you have problems with inconsistent cooling on account of hot and cold spots.

It’s also good if someone in your household deals with allergies, asthma or other respiratory symptoms. That’s because the air is consistently being circulated and filtrated. However, you may have to switch your air filters more regularly.

Having the fan on constantly can also drive up your energy bills. It could also result in the fan wearing out faster and need air conditioning repair.

Your residence may also feel muggier. Air conditioning helps manage humidity by extracting water from the air. But if the fan is continually running, it’s harder for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only operate when your air conditioner does. It’s good if your residence always seems the right temperature, whichever room you’re in.

There are a few disadvantages to using the auto setting. You might run into hot and cold areas in your house and lower air quality. This is due to the fact air isn’t continuously being distributed or being repeatedly filtrated.

On the flip side, you’ll require less energy and won’t have to replace your 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 family.
