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

During the hot weather, running your air conditioning can be your biggest monthly utility cost. So, it’s only natural that you’re looking for approaches to use less energy. That might involve finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit with air conditioner installation.

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

Your air conditioner works with a fan to dispatch the chilled air it creates. You manage this fan at your thermostat by setting it to “auto,” which means the fan will only run when the air conditioner is running. Or you can switch it to “on,” which signifies it will work all the time.

Does putting your AC on “fan” save energy in Rapid City? This isn’t always the case. Typically, using your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also gives a few pluses (and disadvantages) when it comes 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 balance your house’s comfort. This is great if you own a two-story residence, since rooms upstairs can be hotter. It’s also ideal if you have problems with uneven cooling on account of hot and cold areas.

It’s also advantageous if one of your loved ones deals with allergies, asthma or other respiratory symptoms. That’s due to the fact the air is constantly being distributed and purified. On the flip side, you may have to install new air filters more frequently.

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

Your house may also feel more humid. Air conditioning helps balance humidity by removing water from the air. But if the fan is continuously on, it’s challenging for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only work when your air conditioner does. It’s ideal if your home always appears comfortable, no matter what room you’re in.

There are a few downsides to using the auto setting. You might run into hot and cold areas in your residence and lower air quality. This is because air isn’t always being distributed or being constantly purified.

That said, you’ll use less energy and won’t need to change your air filter as regularly. Both are savings that can tally up during the year, so you’ll have to think over what’s best for your family.
