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

July 16, 2020

During the summer, operating your air conditioning can be your biggest monthly utility expense. So, it’s normal that you’re seeking approaches to use less energy. That can include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system during air conditioner installation.

Modifying your air conditioning’s fan setting is another way you can spend less money.

Your air conditioner works with a fan to deliver the cool air it creates. You adjust this fan at your thermostat by changing it to “auto,” which signifies the fan will only run when the air conditioner is cooling. Or you can set it to “on,” which signifies it will operate constantly.

Does putting your AC on “fan” save energy in Alliance? Not necessarily. Typically, running your air conditioner’s fan all the time is going to increase your energy bill slightly.

But it also provides a few pluses (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 go all the time can better equalize your home’s comfort. This is good if you live in a two-story house, since areas upstairs can be more hot. It’s also ideal if you have difficulties with unbalanced cooling on account of hot and cold spots.

It’s also great if one of your family members deals with allergies, asthma or other respiratory issues. That’s due to the fact the air is consistently being dispersed and filtrated. On the flip side, you may have to replace your air filters more frequently.

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

Your house may also appear muggier. Air conditioning helps control humidity by clearing wetness from the air. But if the fan is always working, 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 work when your air conditioner does. It’s great if your residence always seems comfortable, regardless of which area you’re in.

There are a few drawbacks to using the auto setting. You may have hot and cold areas in your residence and reduced air quality. This is since air isn’t always being distributed or being continuously filtered.

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