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

July 16, 2020

During the high temperatures, running your air conditioning can be your biggest monthly electricity expense. So, it’s normal that you’re looking for approaches to use less energy. That might involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model with air conditioner installation.

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

Your air conditioner works with a fan to deliver the chilled 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 going. Or you can adjust it to “on,” which signifies it will run constantly.

Does putting your AC on “fan” save energy in the Rio Grande Valley? This isn’t always the case. Generally, using your air conditioner’s fan all the time is going to increase your energy bill slightly.

But it also gives a few pluses (and drawbacks) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all the time can better balance your house’s comfort. This is great if you have a two-story house, since areas upstairs can be warmer. It’s also great if you have issues with uneven cooling on account of hot and cold rooms.

It’s also great if one of your loved ones has been diagnosed with allergies, asthma or other respiratory symptoms. That’s since the air is constantly being dispersed and filtrated. On the other hand, you may have to put in new air filters more often.

Having the fan on constantly can also increase your energy bills. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your residence may also feel more moist. Air conditioning helps control humidity by extracting wetness from the air. But if the fan is always running, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only operate when your air conditioner does. It’s good if your home always seems comfortable, regardless of which room you’re in.

There are a few downsides to using the auto setting. You could run into hot and cold locations in your residence and decreased air quality. This is because air isn’t constantly flowing or being continuously purified.

On the other hand, you’ll require less energy and won’t be required to replace your air filter as often. Both are savings that can add up throughout the year, so you’ll have to think over what’s right for your household.
