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

July 16, 2020

During the hot weather, using your air conditioning can be your biggest monthly electrical expense. So, it’s only natural that you’re looking for methods to consume less energy. That could include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit with air conditioner installation.

Modifying your air conditioning’s fan setting is another way you can save money.

Your air conditioner works with a fan to distribute the chilled air it makes. You manage this fan at your thermostat by switching it to “auto,” which signifies the fan will only run when the air conditioner is running. Or you can set it to “on,” which signifies it will work constantly.

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

But it also provides a few pluses (and drawbacks) in relation to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better stabilize your family’s comfort. This is ideal if you own a two-story home, since spaces upstairs can be more hot. It’s also ideal if you have problems with uneven cooling because of hot and cold rooms.

It’s also beneficial if one of your family members deals with allergies, asthma or other respiratory symptoms. That’s since the air is continuously being distributed and filtered. However, you may have to install new air filters more frequently.

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

Your residence may also seem more humid. Air conditioning helps balance humidity by drawing wetness from the air. But if the fan is continuously running, it’s challenging for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, because the fan will only operate when your air conditioner does. It’s great if your residence always appears the right temperature, regardless of which area you’re in.

There are a few downsides to using the auto setting. You might run into hot and cold locations in your home and lower air quality. This is due to the fact air isn’t constantly flowing or being constantly filtrated.

On the other hand, you’ll consume reduced 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 ideal for your needs.
