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

July 16, 2020

During the summer, running your air conditioning can be your largest monthly electricity expense. So, it’s normal that you’re checking for methods to use less energy. That might entail trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

Switching your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner relies on a fan to dispatch the cold air it produces. You manage this fan at your thermostat by switching it to “auto,” which signifies the fan will only be on when the air conditioner is cooling. Or you can set it to “on,” which signifies it will work constantly.

Does putting your AC on “fan” save energy in Lexington? This isn’t always the case. Usually, 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 downsides) in regard to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better stabilize your family’s comfort. This is good if you live in a two-story home, since areas upstairs can be more hot. It’s also ideal if you struggle with uneven cooling on account of hot and cold spots.

It’s also beneficial if someone in your household has allergies, asthma or other respiratory issues. That’s since the air is consistently being circulated and purified. On the flip side, you may have to replace your air filters more frequently.

Having the fan on all day can also make your energy bills more expensive. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your residence may also appear more moist. Air conditioning helps manage humidity by clearing wetness from the air. But if the fan is continuously going, it’s more difficult for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only run when your air conditioner does. It’s good if your residence always appears pleasant, regardless of which room you’re in.

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

That said, you’ll consume a lower amount of energy and won’t have to change your air filter as often. Both are savings that can build up throughout the year, so you’ll have to think about what’s best for your home.
