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

July 16, 2020

During the hot weather, running your air conditioning can be your largest monthly electricity expense. So, it’s given that you’re looking for methods to save. That might involve finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model through air conditioner installation.

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

Your air conditioner uses a fan to deliver the chilled air it produces. You control this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is cooling. Or you can switch it to “on,” which means it will work continuously.

Does putting your AC on “fan” save energy in Columbia? This isn’t always the case. Usually, operating your air conditioner’s fan constantly is going to make your energy bill slightly higher.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better balance your home’s comfort. This is ideal if you have a two-story home, since rooms upstairs can be warmer. It’s also ideal if you have issues with inconsistent cooling on account of hot and cold spaces.

It’s also beneficial if one of your loved ones suffers from allergies, asthma or other respiratory symptoms. That’s due to the fact the air is constantly being distributed and filtrated. On the flip side, you may have to put in new air filters more regularly.

Having the fan on all day can also increase your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

Your residence may also appear muggier. Air conditioning helps control humidity by removing wetness from the air. But if the fan is continuously running, it’s more difficult 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 great if your home always seems comfortable, whichever area you’re in.

There are a few drawbacks to using the auto setting. You might have hot and cold areas in your home and lower air quality. This is because air isn’t constantly being distributed or being repeatedly purified.

That said, you’ll require less energy and won’t have to change your 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 household.
