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

During the high temperatures, operating your air conditioning can be your biggest monthly utility charge. So, it’s only natural that you’re checking for approaches to use less energy. That could entail trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner works with a fan to dispatch the cold air it makes. You manage this fan at your thermostat by changing it to “auto,” which signifies the fan will only run when the air conditioner is going. Or you can set it to “on,” which means it will be on continuously.

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

But it also offers a few pluses (and disadvantages) in relation to your family’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 family’s comfort. This is good if you have a two-story house, since spaces upstairs can be hotter. It’s also great if you have problems with inconsistent cooling because of hot and cold spots.

It’s also advantageous if someone in your household has been diagnosed with allergies, asthma or other respiratory problems. That’s due to the fact the air is constantly being distributed and filtrated. On the other hand, you may have to replace your air filters more frequently.

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

Your house may also feel muggier. Air conditioning helps manage humidity by extracting water from the air. But if the fan is continuously going, it’s more difficult for moisture to drain from the condenser outdoors.

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 good if your home always seems the right temperature, whichever room you’re in.

There are a few downsides to using the auto setting. You may experience hot and cold locations in your residence and lower air quality. This is due to the fact air isn’t constantly flowing or being continuously purified.

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