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

July 16, 2020

During the hot weather, operating your air conditioning can be your highest monthly electricity expense. So, it’s given that you’re looking for approaches to consume less energy. That can entail using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit with air conditioner installation.

Switching your air conditioning’s fan setting is another way you can save money.

Your air conditioner relies on a fan to dispatch the chilled air it makes. You control this fan at your thermostat by changing it to “auto,” which indicates the fan will only be on when the air conditioner is running. Or you can set it to “on,” which indicates it will operate all the time.

Does putting your AC on “fan” save energy in Grand Prairie? Not always. Typically, using your air conditioner’s fan all the time is going to make your energy bill slightly higher.

But it also provides a few perks (and downsides) in relation to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better equalize your house’s comfort. This is ideal if you live in a two-story house, since spaces upstairs can be hotter. It’s also great if you have difficulties with uneven cooling on account of hot and cold rooms.

It’s also beneficial if one of your loved ones has been diagnosed with allergies, asthma or other respiratory issues. That’s because the air is constantly being distributed and filtrated. On the other hand, you may have to replace your air filters more often.

Having the fan on constantly can also drive up your energy bills. It could also make the fan wear out faster and need air conditioning repair.

Your house may also appear muggier. Air conditioning helps balance humidity by extracting water from the air. But if the fan is continuously running, it’s harder for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only operate when your air conditioner does. It’s good if your house always appears pleasant, whichever spot you’re in.

There are a few downsides to using the auto setting. You could run into hot and cold locations in your house and lower air quality. This is due to the fact air isn’t always flowing or being repeatedly filtered.

On the other hand, you’ll use reduced energy and won’t need to get a new air filter as regularly. Both are savings that can tally up during the year, so you’ll have to think about what’s best for your home.
