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

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

Switching your air conditioning’s fan setting is an additional way you can conserve money.

Your air conditioner uses a fan to deliver the chilled air it creates. You control this fan at your thermostat by changing it to “auto,” which indicates the fan will only run when the air conditioner is going. Or you can adjust it to “on,” which indicates it will work constantly.

Does putting your AC on “fan” save energy in Saint Marys? Not always. Typically, operating your air conditioner’s fan all day is going to make your energy bill slightly higher.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better equalize your house’s comfort. This is ideal if you have a two-story home, since spaces upstairs can be more hot. It’s also great if you struggle with inconsistent cooling due to hot and cold spaces.

It’s also great if someone in your household suffers from allergies, asthma or other respiratory issues. That’s because the air is continuously being distributed and purified. On the other hand, you may have to replace your air filters more frequently.

Having the fan on constantly can also increase your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

Your home may also feel more humid. Air conditioning helps manage humidity by clearing water from the air. But if the fan is constantly running, it’s challenging for moisture to flow from the condenser outdoors.

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 residence always feels pleasant, regardless of which spot you’re in.

There are a few downsides to using the auto setting. You may run into hot and cold spots in your home and reduced air quality. This is since air isn’t always moving or being repeatedly filtrated.

On the flip side, you’ll consume reduced energy and won’t be required to change your air filter as frequently. Both are savings that can build up throughout the year, so you’ll have to think over what’s right for your household.
