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

July 16, 2020

During the hot weather, operating your air conditioning can be your largest monthly utility cost. So, it’s normal that you’re seeking methods to use less energy. That could entail finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit through 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 dispatch the chilled air it creates. You manage this fan at your thermostat by switching it to “auto,” which signifies the fan will only work when the air conditioner is working. Or you can switch it to “on,” which means it will run continuously.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better stabilize your home’s comfort. This is great if you live in a two-story house, since areas upstairs can be more hot. It’s also great if you have issues with uneven cooling on account of hot and cold areas.

It’s also good if one of your family members has been diagnosed with allergies, asthma or other respiratory illnesses. That’s because the air is continuously being circulated and filtered. However, you may have to install new air filters more often.

Having the fan on all the time can also drive up your energy bills. It could also result in the fan wearing out faster and need air conditioning repair.

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

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only operate when your air conditioner does. It’s ideal if your residence always appears comfy, no matter what spot you’re in.

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

On the flip side, you’ll consume a lower amount of energy and won’t need to switch you air filter as regularly. Both are savings that can build up throughout the year, so you’ll have to consider what’s best for your home.
