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

July 16, 2020

During the summer, operating your air conditioning can be your biggest monthly electricity charge. So, it’s normal that you’re seeking ways to consume less energy. That could include trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner relies on a fan to deliver the cold air it produces. You control this fan at your thermostat by changing it to “auto,” which indicates the fan will only be on when the air conditioner is cooling. Or you can switch it to “on,” which indicates it will operate constantly.

Does putting your AC on “fan” save energy in Greensburg? Not necessarily. Generally, running your air conditioner’s fan all the time is going to make your energy bill slightly higher.

But it also provides a few perks (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 run all day can better stabilize your home’s comfort. This is ideal if you live in a two-story residence, since rooms upstairs can be more hot. It’s also great if you have difficulties with inconsistent cooling on account of hot and cold areas.

It’s also advantageous if one of your loved ones has allergies, asthma or other respiratory symptoms. That’s because the air is constantly being distributed and filtered. On the flip side, you may have to change your air filters more frequently.

Having the fan on all day can also increase your energy bills. It could also result in the fan wearing out sooner and need air conditioning repair.

Your house may also appear more moist. Air conditioning helps manage humidity by extracting wetness from the air. But if the fan is continually going, it’s challenging for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only operate when your air conditioner does. It’s ideal if your residence always appears comfy, regardless of which area you’re in.

There are a few drawbacks to using the auto setting. You could experience hot and cold locations in your home and reduced air quality. This is because air isn’t continuously flowing or being repeatedly filtered.

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