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

During the hot weather, using your air conditioning can be your biggest monthly utility charge. So, it’s normal that you’re seeking approaches to use less energy. That may involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model during air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cold air it makes. You control this fan at your thermostat by changing it to “auto,” which indicates the fan will only work when the air conditioner is cooling. Or you can adjust it to “on,” which means it will run all the time.

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

But it also offers a few advantages (and drawbacks) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better equalize your house’s comfort. This is great if you own a two-story residence, since areas upstairs can be warmer. It’s also good if you have problems with unbalanced cooling because of hot and cold spaces.

It’s also advantageous if someone in your household deals with allergies, asthma or other respiratory issues. That’s since the air is continuously being circulated and purified. On the flip side, you may have to install new air filters more often.

Having the fan on all day can also increase your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

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

Air Conditioner Fan Set to “Auto”

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

There are a few disadvantages to using the auto setting. You may have hot and cold spots in your home and lower air quality. This is due to the fact air isn’t always being distributed or being continuously filtered.

That said, you’ll consume less energy and won’t be required to switch you air filter as regularly. Both are savings that can tally up throughout the year, so you’ll have to think about what’s right for your family.
