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

July 16, 2020

During the hot weather, running your air conditioning can be your biggest monthly electricity charge. So, it’s normal that you’re looking for approaches to save. That could involve finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model with air conditioner installation.

Modifying your air conditioning’s fan setting is an additional way you can conserve money.

Your air conditioner uses a fan to dispatch the cold air it produces. You adjust this fan at your thermostat by switching it to “auto,” which signifies the fan will only be on when the air conditioner is running. Or you can switch it to “on,” which means it will run all the time.

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

But it also offers a few perks (and drawbacks) in regard to your residence’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 great if you have a two-story house, since spaces upstairs can be warmer. It’s also ideal if you have problems with unbalanced cooling on account of hot and cold spaces.

It’s also good if one of your family members has been diagnosed with allergies, asthma or other respiratory problems. That’s due to the fact the air is continuously being dispersed and purified. On the other hand, you may have to install new air filters more frequently.

Having the fan on all day can also make your energy bills more expensive. It could also make the fan wear out prematurely and need air conditioning repair.

Your house may also seem muggier. Air conditioning helps manage humidity by drawing moisture from the air. But if the fan is constantly on, it’s challenging for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only operate when your air conditioner does. It’s ideal if your house always feels comfy, no matter what spot you’re in.

There are a few downsides to using the auto setting. You may run into hot and cold spots in your house and decreased air quality. This is because air isn’t continuously flowing or being repeatedly filtered.

On the flip side, you’ll require reduced energy and won’t need to change your air filter as frequently. Both are savings that can add up during the year, so you’ll have to consider what’s best for your needs.
