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

July 16, 2020

During the hot weather, operating your air conditioning can be your biggest monthly utility expense. So, it’s normal that you’re seeking approaches to consume less energy. That could involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

Modifying your air conditioning’s fan setting is an additional way you can save money.

Your air conditioner relies on a fan to deliver the cold air it makes. You adjust this fan at your thermostat by switching it to “auto,” which means the fan will only work when the air conditioner is running. Or you can set it to “on,” which signifies it will operate continuously.

Does putting your AC on “fan” save energy in Chatsworth? 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 drawbacks) when it comes to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better stabilize your home’s comfort. This is good if you have a two-story house, since rooms upstairs can be hotter. It’s also great if you have issues with unbalanced cooling on account of hot and cold rooms.

It’s also good if one of your loved ones has allergies, asthma or other respiratory symptoms. That’s because the air is continuously being distributed and purified. On the other hand, you may have to install new air filters more regularly.

Having the fan on constantly can also make your energy bills more expensive. It could also cause the fan to wear out sooner and need air conditioning repair.

Your house may also feel more moist. Air conditioning helps balance humidity by drawing wetness from the air. But if the fan is always running, it’s more difficult for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only operate when your air conditioner does. It’s ideal if your residence always seems cool, whichever area you’re in.

There are a few disadvantages to using the auto setting. You may experience hot and cold areas in your residence and reduced air quality. This is because air isn’t constantly moving or being constantly filtrated.

That said, you’ll use a lower amount of energy and won’t be required to switch you air filter as frequently. Both are savings that can add up over the year, so you’ll have to think over what’s right for your home.
