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

During the summer, operating your air conditioning can be your biggest monthly electricity cost. So, it’s normal that you’re seeking ways to use less energy. That could involve finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner relies on a fan to deliver the chilled air it makes. You control this fan at your thermostat by setting it to “auto,” which indicates the fan will only run when the air conditioner is operating. Or you can set it to “on,” which means it will run constantly.

Does putting your AC on “fan” save energy in Marshfield? Not necessarily. Generally, operating your air conditioner’s fan all the time is going to make your energy bill slightly higher.

But it also has a few advantages (and downsides) when it comes 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 house’s comfort. This is good if you own a two-story home, since rooms upstairs can be warmer. It’s also great if you have difficulties with unbalanced cooling on account of hot and cold spots.

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

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

Your residence may also seem more humid. Air conditioning helps manage humidity by clearing moisture from the air. But if the fan is continually working, it’s challenging for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only work when your air conditioner does. It’s ideal if your house always seems cool, no matter what area you’re in.

There are a few drawbacks to using the auto setting. You may run into hot and cold spots in your residence and lower air quality. This is due to the fact air isn’t constantly being distributed or being constantly filtered.

That said, you’ll require reduced energy and won’t need to change your air filter as regularly. Both are savings that can add up during the year, so you’ll have to think about what’s ideal for your household.
