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 cost. So, it’s given that you’re checking for ways to consume less energy. That can entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model during 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 distribute the cold air it produces. You control this fan at your thermostat by setting it to “auto,” which indicates the fan will only run when the air conditioner is working. Or you can set it to “on,” which means it will work all the time.

Does putting your AC on “fan” save energy in Albuquerque? This isn’t always the case. Usually, using your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also gives a few perks (and drawbacks) when it comes to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better equalize your house’s comfort. This is great if you live in a two-story residence, since areas upstairs can be more hot. It’s also good if you struggle with inconsistent cooling on account of hot and cold rooms.

It’s also good if someone in your household deals with allergies, asthma or other respiratory symptoms. That’s due to the fact the air is continuously being circulated and filtered. On the flip side, you may have to replace your air filters more frequently.

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

Your house may also seem muggier. Air conditioning helps manage humidity by clearing moisture from the air. But if the fan is continuously running, it’s harder for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only operate when your air conditioner does. It’s great if your home always appears comfy, whichever spot you’re in.

There are a few disadvantages to using the auto setting. You might run into hot and cold locations in your residence and lower air quality. This is due to the fact air isn’t constantly flowing or being repeatedly purified.

That said, you’ll use less energy and won’t have to switch you air filter as regularly. Both are savings that can add up during the year, so you’ll have to think about what’s best for your needs.
