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

During the summer, operating your air conditioning can be your largest monthly electrical cost. So, it’s given that you’re seeking methods to consume less energy. That can include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

Switching your air conditioning’s fan setting is a second way you can save money.

Your air conditioner uses a fan to deliver the cold air it creates. You control this fan at your thermostat by setting it to “auto,” which means the fan will only work when the air conditioner is cooling. Or you can switch it to “on,” which signifies it will operate continuously.

Does putting your AC on “fan” save energy in West Columbia? This isn’t always the case. Typically, running your air conditioner’s fan all day is going to make your energy bill slightly higher.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all the time can better stabilize your house’s comfort. This is great if you have a two-story home, since rooms upstairs can be warmer. It’s also ideal if you have problems with inconsistent cooling due to hot and cold spaces.

It’s also beneficial if one of your loved ones deals with allergies, asthma or other respiratory symptoms. That’s because the air is consistently being circulated and purified. On the other hand, you may have to put in new air filters more regularly.

Having the fan on all day can also drive up your energy bills. It could also make the fan wear out faster and need air conditioning repair.

Your residence may also seem muggier. Air conditioning helps control humidity by drawing water from the air. But if the fan is continually on, it’s more difficult for moisture to drain from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only run when your air conditioner does. It’s good if your residence always feels comfortable, whichever area you’re in.

There are a few downsides to using the auto setting. You could experience hot and cold areas in your residence and reduced air quality. This is since air isn’t constantly flowing or being continuously purified.

On the other hand, you’ll consume reduced energy and won’t need to change your air filter as frequently. Both are savings that can build up throughout the year, so you’ll have to think about what’s right for your home.
