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

July 16, 2020

During the high temperatures, running your air conditioning can be your highest monthly electricity charge. So, it’s only natural that you’re looking for approaches to consume less energy. That could include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner uses a fan to dispatch the cold air it creates. You adjust this fan at your thermostat by switching it to “auto,” which indicates the fan will only be on when the air conditioner is cooling. Or you can switch it to “on,” which means it will be on continuously.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better balance your home’s comfort. This is ideal if you own a two-story house, since areas upstairs can be more hot. It’s also ideal if you have issues with uneven cooling because of hot and cold spots.

It’s also advantageous if one of your family members deals with allergies, asthma or other respiratory problems. That’s because the air is continuously being distributed and filtered. However, you may have to install new air filters more regularly.

Having the fan on all day can also drive up your energy bills. It could also result in the fan wearing out prematurely and need air conditioning repair.

Your home may also seem more humid. Air conditioning helps balance humidity by drawing wetness from the air. But if the fan is continually working, it’s harder for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only work when your air conditioner does. It’s good if your home always seems comfy, regardless of which room you’re in.

There are a few drawbacks to using the auto setting. You may run into hot and cold locations in your home and decreased air quality. This is because air isn’t constantly flowing or being continuously purified.

That said, you’ll consume a lower amount of energy and won’t need to replace your air filter as often. Both are savings that can add up throughout the year, so you’ll have to consider what’s ideal for your home.
