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

July 16, 2020

During the hot weather, using your air conditioning can be your largest monthly utility charge. So, it’s given that you’re seeking ways to consume less energy. That can involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner uses a fan to dispatch the chilled air it makes. You control this fan at your thermostat by setting it to “auto,” which means the fan will only work when the air conditioner is running. Or you can adjust it to “on,” which indicates it will work continuously.

Does putting your AC on “fan” save energy in Mechanicsburg? Not always. Generally, using your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also gives a few advantages (and drawbacks) 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 house’s comfort. This is great if you live in a two-story residence, since spaces upstairs can be more hot. It’s also great if you struggle with inconsistent cooling on account of hot and cold areas.

It’s also beneficial if one of your loved ones suffers from allergies, asthma or other respiratory problems. That’s because the air is constantly being distributed and purified. However, you may have to put in new air filters more frequently.

Having the fan on all day can also make your energy bills more expensive. It could also result in the fan wearing out more quickly and need air conditioning repair.

Your residence may also appear more moist. Air conditioning helps manage humidity by extracting wetness from the air. But if the fan is continually working, it’s challenging for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

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

There are a few disadvantages to using the auto setting. You could run into hot and cold areas in your home and reduced air quality. This is because air isn’t always moving or being continuously filtered.

On the flip side, you’ll use less energy and won’t be required to switch you air filter as regularly. Both are savings that can add up throughout the year, so you’ll have to consider what’s best for your family.
