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

July 16, 2020

During the high temperatures, operating your air conditioning can be your largest monthly electrical cost. So, it’s given that you’re looking for methods to consume less energy. That can entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

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

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

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

But it also gives a few advantages (and downsides) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all the time can better balance your family’s comfort. This is ideal if you have a two-story house, since spaces upstairs can be more hot. It’s also ideal if you have issues with uneven cooling because of hot and cold spaces.

It’s also good if someone in your household has been diagnosed with allergies, asthma or other respiratory illnesses. That’s since the air is constantly being distributed and purified. On the flip side, you may have to replace your air filters more regularly.

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

Your home may also seem more humid. Air conditioning helps balance humidity by extracting water from the air. But if the fan is continuously running, it’s challenging 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 run when your air conditioner does. It’s great if your house always appears comfortable, whichever area you’re in.

There are a few disadvantages to using the auto setting. You might have hot and cold locations in your home and reduced air quality. This is due to the fact air isn’t always moving or being repeatedly filtered.

That said, you’ll use less energy and won’t need to replace your air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to think about what’s best for your needs.
