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

During the high temperatures, running your air conditioning can be your largest monthly electricity cost. So, it’s normal that you’re seeking approaches to use less energy. That might entail using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit through air conditioner installation.

Switching your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner works with a fan to distribute the cool air it creates. You manage this fan at your thermostat by changing it to “auto,” which means the fan will only work when the air conditioner is running. Or you can set it to “on,” which indicates it will be on constantly.

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

But it also has a few perks (and drawbacks) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better stabilize your family’s comfort. This is ideal if you own a two-story home, since spaces upstairs can be hotter. It’s also good if you have issues with unbalanced cooling because of hot and cold areas.

It’s also great if one of your family members deals with allergies, asthma or other respiratory symptoms. That’s because the air is continuously being dispersed and purified. On the other hand, you may have to switch your air filters more regularly.

Having the fan on constantly can also make your energy bills more expensive. It could also cause the fan to wear out faster and need air conditioning repair.

Your home may also appear more moist. Air conditioning helps control humidity by extracting water from the air. But if the fan is always running, it’s more difficult for moisture to drip from the condenser outdoors.

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 ideal if your residence always feels cool, no matter what area you’re in.

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

On the flip side, you’ll use a lower amount of energy and won’t be required to change your air filter as frequently. Both are savings that can build up over the year, so you’ll have to think over what’s right for your needs.
