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

During the hot weather, running your air conditioning can be your highest monthly utility expense. So, it’s given that you’re checking for methods to consume less energy. That might involve using an energy-efficient AC setting or even stepping up 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 works with a fan to distribute the cold air it makes. You manage this fan at your thermostat by switching it to “auto,” which signifies the fan will only be on when the air conditioner is cooling. Or you can set it to “on,” which signifies it will operate constantly.

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

But it also provides a few pluses (and disadvantages) in regard 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 family’s comfort. This is good if you have a two-story residence, since areas upstairs can be hotter. It’s also good if you have issues with uneven cooling on account of hot and cold rooms.

It’s also beneficial if one of your family members suffers from allergies, asthma or other respiratory symptoms. That’s because the air is continuously being circulated and filtrated. On the other hand, you may have to install new air filters more frequently.

Having the fan on constantly can also drive up your energy bills. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your home may also appear more humid. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is always on, it’s challenging for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only go when your air conditioner does. It’s ideal if your home always feels the right temperature, no matter what area you’re in.

There are a few downsides to using the auto setting. You might have hot and cold areas in your home and decreased air quality. This is because air isn’t constantly being distributed or being constantly purified.

That said, you’ll use reduced energy and won’t be required to replace your air filter as frequently. Both are savings that can add up throughout the year, so you’ll have to think over what’s best for your home.
