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

During the summer, operating your air conditioning can be your highest monthly electricity cost. So, it’s given that you’re seeking methods to consume less energy. That can include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner works with a fan to dispatch the cool air it creates. You control this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is cooling. Or you can set it to “on,” which means it will run constantly.

Does putting your AC on “fan” save energy in Florissant? Not necessarily. Typically, using your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also provides 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 continuously can better balance your house’s comfort. This is ideal if you live in a two-story house, since areas upstairs can be warmer. It’s also great if you struggle with inconsistent cooling due to hot and cold areas.

It’s also advantageous if one of your family members has allergies, asthma or other respiratory illnesses. That’s due to the fact the air is consistently being distributed and filtrated. On the flip side, you may have to change your air filters more regularly.

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

Your residence may also seem muggier. Air conditioning helps control humidity by extracting moisture from the air. But if the fan is continuously working, it’s harder for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only run when your air conditioner does. It’s great if your residence always feels cool, regardless of which area you’re in.

There are a few disadvantages to using the auto setting. You might experience hot and cold spots in your residence and reduced air quality. This is because air isn’t always being distributed or being constantly purified.

On the other hand, you’ll consume a lower amount of energy and won’t be required to switch you air filter as frequently. Both are savings that can tally up over the year, so you’ll have to think over what’s ideal for your home.
