Which Consumes 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 cost. So, it’s normal that you’re looking for ways to consume less energy. That can include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit through air conditioner installation.

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

Your air conditioner relies on a fan to deliver the chilled air it creates. You manage this fan at your thermostat by changing it to “auto,” which means the fan will only run when the air conditioner is cooling. Or you can set it to “on,” which indicates it will be on constantly.

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

But it also offers a few pluses (and disadvantages) as far as your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better equalize your house’s comfort. This is good if you own a two-story home, since spaces upstairs can be hotter. It’s also great if you have difficulties with unbalanced cooling on account of hot and cold spaces.

It’s also beneficial if someone in your household suffers from allergies, asthma or other respiratory symptoms. That’s because the air is continuously being dispersed and purified. However, you may have to change your air filters more frequently.

Having the fan on constantly can also make your energy bills more expensive. It could also make the fan wear out faster and need air conditioning repair.

Your house may also feel more humid. Air conditioning helps balance humidity by removing wetness from the air. But if the fan is continually working, it’s challenging for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

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

There are a few disadvantages to using the auto setting. You could have hot and cold areas in your home and decreased air quality. This is since air isn’t continuously moving or being repeatedly filtered.

That said, you’ll require a lower amount of energy and won’t need to get a new air filter as often. Both are savings that can add up throughout the year, so you’ll have to consider what’s ideal for your needs.
