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

During the high temperatures, running your air conditioning can be your largest monthly utility expense. So, it’s only natural that you’re looking for approaches to consume less energy. That might include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit through air conditioner installation.

Switching your air conditioning’s fan setting is another way you can save money.

Your air conditioner works with a fan to dispatch the chilled air it makes. You adjust 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 adjust it to “on,” which means it will be on continuously.

Does putting your AC on “fan” save energy in Carlsbad? This isn’t always the case. Generally, operating your air conditioner’s fan all the time is going to increase your energy bill slightly.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better stabilize your home’s comfort. This is good if you live in a two-story home, since spaces upstairs can be hotter. It’s also great if you have issues with inconsistent cooling because of hot and cold spaces.

It’s also great if someone in your household suffers from allergies, asthma or other respiratory illnesses. That’s due to the fact the air is continuously being dispersed and filtrated. However, you may have to change your air filters more frequently.

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 house may also appear muggier. Air conditioning helps balance humidity by clearing moisture from the air. But if the fan is constantly running, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only work when your air conditioner does. It’s great if your home always seems comfy, whichever area you’re in.

There are a few disadvantages to using the auto setting. You could run into hot and cold spots in your house and reduced air quality. This is due to the fact air isn’t continuously flowing or being continuously filtrated.

On the other hand, you’ll use a lower amount of energy and won’t have to replace your air filter as often. Both are savings that can tally up during the year, so you’ll have to consider what’s best for your needs.
