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

During the high temperatures, operating your air conditioning can be your highest monthly utility expense. So, it’s given that you’re seeking approaches to consume less energy. That may entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner works with a fan to distribute the cold air it creates. You adjust this fan at your thermostat by setting it to “auto,” which indicates the fan will only work when the air conditioner is cooling. Or you can adjust it to “on,” which signifies it will be on all the time.

Does putting your AC on “fan” save energy in Manassas Park? Not always. Generally, running your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also provides a few advantages (and drawbacks) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better balance your family’s comfort. This is ideal if you live in a two-story home, since spaces upstairs can be warmer. It’s also good if you have issues with uneven cooling due to hot and cold spots.

It’s also good if someone in your household has allergies, asthma or other respiratory illnesses. That’s because the air is constantly being distributed and filtered. On the other hand, you may have to install new air filters more regularly.

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

Your home may also appear more humid. Air conditioning helps control humidity by extracting moisture from the air. But if the fan is always on, it’s harder for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only run when your air conditioner does. It’s great if your house always feels comfortable, no matter what spot you’re in.

There are a few downsides to using the auto setting. You may run into hot and cold areas in your residence and reduced air quality. This is due to the fact air isn’t always moving or being constantly filtered.

On the other hand, you’ll require a lower amount of energy and won’t have to replace your air filter as often. Both are savings that can build up during the year, so you’ll have to consider what’s ideal for your family.
