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

During the summer, using your air conditioning can be your largest monthly utility charge. So, it’s normal that you’re checking for ways to use less energy. That may entail trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model through air conditioner installation.

Regulating your air conditioning’s fan setting is a second way you can spend less money.

Your air conditioner uses a fan to dispatch the cool air it produces. You adjust this fan at your thermostat by switching it to “auto,” which signifies the fan will only work when the air conditioner is going. Or you can switch it to “on,” which signifies it will work continuously.

Does putting your AC on “fan” save energy in Plainfield? Not always. Typically, running your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also has 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 operate all day can better equalize your house’s comfort. This is good if you have a two-story home, since areas upstairs can be more hot. It’s also good if you struggle with inconsistent cooling due to hot and cold areas.

It’s also beneficial if someone in your household suffers from allergies, asthma or other respiratory problems. That’s since the air is continuously being circulated and filtrated. However, you may have to switch your air filters more regularly.

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

Your house may also feel more moist. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is continuously going, it’s harder for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only go when your air conditioner does. It’s ideal if your home always appears the right temperature, whichever area you’re in.

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

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