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

July 16, 2020

During the high temperatures, using your air conditioning can be your largest monthly electricity charge. So, it’s only natural that you’re checking for methods to use less energy. That could include trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner uses a fan to distribute the chilled air it creates. You adjust this fan at your thermostat by setting it to “auto,” which indicates the fan will only be on when the air conditioner is working. Or you can switch it to “on,” which signifies it will operate all the time.

Does putting your AC on “fan” save energy in Perry? Not necessarily. Generally, operating your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also provides a few advantages (and downsides) when it comes to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better balance your house’s comfort. This is great if you own a two-story home, since rooms upstairs can be more hot. It’s also good if you struggle with uneven cooling on account of hot and cold spots.

It’s also beneficial if one of your family members deals with allergies, asthma or other respiratory illnesses. That’s due to the fact the air is constantly being circulated and filtered. On the other hand, you may have to replace your air filters more regularly.

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

Your house may also seem more humid. Air conditioning helps balance humidity by clearing water from the air. But if the fan is always working, it’s harder for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only work when your air conditioner does. It’s ideal if your house always appears pleasant, whichever spot you’re in.

There are a few downsides to using the auto setting. You may experience hot and cold locations in your residence and decreased air quality. This is since air isn’t continuously flowing or being repeatedly filtered.

On the flip side, you’ll need a lower amount of energy and won’t be required to change your air filter as frequently. Both are savings that can build up over the year, so you’ll have to think over what’s right for your needs.
