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

July 16, 2020

During the hot weather, running your air conditioning can be your highest monthly utility cost. So, it’s normal that you’re seeking methods to use less energy. That can involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner works with a fan to deliver the cold air it makes. You manage this fan at your thermostat by setting it to “auto,” which indicates the fan will only run when the air conditioner is running. Or you can set it to “on,” which signifies it will run constantly.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better equalize your home’s comfort. This is great if you own a two-story home, since areas upstairs can be more hot. It’s also good if you have issues with inconsistent cooling because of hot and cold spots.

It’s also good if one of your loved ones deals with allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being circulated and filtrated. On the flip side, 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 more quickly and need air conditioning repair.

Your residence may also feel more moist. Air conditioning helps balance humidity by drawing moisture from the air. But if the fan is constantly on, it’s challenging for moisture to drain from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only go when your air conditioner does. It’s great if your residence always seems the right temperature, regardless of which spot you’re in.

There are a few drawbacks to using the auto setting. You might have hot and cold locations in your residence and reduced air quality. This is because air isn’t always moving or being continuously purified.

That said, you’ll use a lower amount of energy and won’t have to switch you air filter as frequently. Both are savings that can build up throughout the year, so you’ll have to think about what’s ideal for your needs.
