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

July 16, 2020

During the high temperatures, running your air conditioning can be your biggest monthly electrical expense. So, it’s normal that you’re seeking ways to save. That may entail trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system 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 dispatch the chilled air it makes. You control this fan at your thermostat by setting it to “auto,” which means the fan will only work when the air conditioner is going. Or you can adjust it to “on,” which means it will be on constantly.

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

But it also gives a few pluses (and disadvantages) in regard to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better balance your family’s comfort. This is good if you have a two-story house, since spaces upstairs can be hotter. It’s also good if you have difficulties with unbalanced cooling because of hot and cold areas.

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

Having the fan on constantly can also drive up your energy bills. It could also result in the fan wearing out sooner and need air conditioning repair.

Your home may also seem muggier. Air conditioning helps balance humidity by drawing moisture from the air. But if the fan is always running, it’s harder for moisture to flow from the condenser outside.

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 home always appears the right temperature, regardless of which area you’re in.

There are a few downsides to using the auto setting. You could experience hot and cold spots in your home and reduced air quality. This is due to the fact air isn’t always being distributed or being continuously filtrated.

On the flip side, you’ll use reduced energy and won’t need to switch you air filter as regularly. Both are savings that can build up over the year, so you’ll have to consider what’s ideal for your needs.
