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

July 16, 2020

During the summer, using your air conditioning can be your largest monthly utility expense. So, it’s normal that you’re checking for ways to use less energy. That could include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

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

Your air conditioner uses a fan to deliver the cold air it produces. You manage this fan at your thermostat by changing it to “auto,” which indicates the fan will only run 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 Plainfield? This isn’t always the case. Generally, running your air conditioner’s fan constantly is going to increase your energy bill slightly.

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

Air Conditioner Fan Set to “On”

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

It’s also great if someone in your household has been diagnosed with allergies, asthma or other respiratory illnesses. That’s due to the fact the air is continuously being circulated and filtered. On the flip side, you may have to put in new air filters more regularly.

Having the fan on constantly can also drive up your energy bills. It could also make the fan wear out prematurely and need air conditioning repair.

Your residence may also seem more moist. Air conditioning helps control humidity by clearing moisture from the air. But if the fan is continually on, it’s more difficult for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only run when your air conditioner does. It’s good if your home always appears the right temperature, regardless of which area you’re in.

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

That said, you’ll consume reduced energy and won’t have to change your air filter as often. Both are savings that can tally up over the year, so you’ll have to think over what’s right for your family.
