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

July 16, 2020

During the hot weather, using your air conditioning can be your biggest monthly electrical expense. So, it’s normal that you’re looking for methods to save. That could entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system with air conditioner installation.

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

Your air conditioner uses a fan to dispatch the chilled air it makes. You manage this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is going. Or you can adjust it to “on,” which indicates it will be on continuously.

Does putting your AC on “fan” save energy in Hamilton? Not always. Generally, using your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also has a few perks (and disadvantages) in regard to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better balance your house’s comfort. This is good if you own a two-story house, since spaces upstairs can be warmer. It’s also good if you have issues with uneven cooling because of hot and cold spots.

It’s also good if one of your loved ones suffers from allergies, asthma or other respiratory issues. That’s since the air is constantly being distributed and filtered. On the other hand, you may have to switch your air filters more regularly.

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

Your home may also feel muggier. Air conditioning helps manage humidity by removing moisture from the air. But if the fan is continuously on, it’s more difficult for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only operate when your air conditioner does. It’s ideal if your house always feels pleasant, whichever room you’re in.

There are a few drawbacks to using the auto setting. You could have hot and cold locations in your home and reduced air quality. This is due to the fact air isn’t always moving or being constantly filtrated.

On the other hand, you’ll use reduced energy and won’t be required to change your air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to think about what’s ideal for your family.
