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

July 16, 2020

During the high temperatures, operating your air conditioning can be your highest monthly electrical charge. So, it’s given that you’re checking for approaches to use less energy. That might entail using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit through air conditioner installation.

Regulating your air conditioning’s fan setting is another way you can conserve money.

Your air conditioner relies on a fan to deliver the cool air it creates. You adjust this fan at your thermostat by setting it to “auto,” which indicates the fan will only run when the air conditioner is running. Or you can set it to “on,” which means it will run continuously.

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

But it also offers a few pluses (and drawbacks) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better balance your house’s comfort. This is ideal if you live in a two-story home, since spaces upstairs can be hotter. It’s also great if you have problems with unbalanced cooling because of hot and cold areas.

It’s also good if one of your loved ones suffers from allergies, asthma or other respiratory issues. That’s due to the fact the air is consistently being dispersed and purified. However, 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 result in the fan wearing out more quickly and need air conditioning repair.

Your house may also feel muggier. Air conditioning helps manage humidity by clearing wetness from the air. But if the fan is constantly going, it’s more difficult for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only go when your air conditioner does. It’s ideal if your residence always feels comfortable, regardless of which area you’re in.

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

On the other hand, you’ll consume reduced energy and won’t need to change your air filter as often. Both are savings that can build up over the year, so you’ll have to consider what’s right for your needs.
