Which Takes 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 expense. So, it’s given that you’re looking for ways to save. That might involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model with air conditioner installation.

Adjusting your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner relies on a fan to dispatch the cold air it makes. 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 running. Or you can set it to “on,” which signifies it will work constantly.

Does putting your AC on “fan” save energy in Haines City? Not necessarily. Typically, using your air conditioner’s fan all day is going to make your energy bill slightly higher.

But it also offers a few advantages (and drawbacks) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better equalize your family’s comfort. This is ideal if you live in a two-story residence, since areas upstairs can be hotter. It’s also ideal if you have difficulties with inconsistent cooling on account of hot and cold spots.

It’s also good if one of your loved ones has allergies, asthma or other respiratory issues. That’s since the air is consistently being dispersed and filtered. However, you may have to put in new air filters more frequently.

Having the fan on constantly can also make your energy bills more expensive. It could also result in the fan wearing out faster and need air conditioning repair.

Your house may also seem more humid. Air conditioning helps manage humidity by removing water from the air. But if the fan is always running, it’s challenging for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only run when your air conditioner does. It’s good if your residence always feels the right temperature, whichever area you’re in.

There are a few drawbacks to using the auto setting. You may run into hot and cold spots in your residence and decreased air quality. This is since air isn’t constantly moving or being repeatedly purified.

That said, you’ll use a lower amount of energy and won’t need to get a new air filter as often. Both are savings that can build up throughout the year, so you’ll have to consider what’s right for your household.
