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

July 16, 2020

During the hot weather, using your air conditioning can be your biggest monthly utility expense. So, it’s normal that you’re checking for methods to save. That could include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model 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 deliver the chilled air it makes. You adjust this fan at your thermostat by setting it to “auto,” which indicates the fan will only run when the air conditioner is going. Or you can set it to “on,” which indicates it will be on all the time.

Does putting your AC on “fan” save energy in Grove City? This isn’t always the case. Generally, using your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also gives a few perks (and downsides) when it comes to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

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

It’s also good if someone in your household suffers from allergies, asthma or other respiratory problems. That’s since the air is continuously being dispersed and filtered. 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 make the fan wear out more quickly and need air conditioning repair.

Your house may also seem muggier. Air conditioning helps manage humidity by clearing wetness from the air. But if the fan is always working, it’s more difficult for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

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

There are a few drawbacks to using the auto setting. You may have hot and cold areas in your home and decreased air quality. This is since air isn’t always flowing or being continuously purified.

That said, you’ll require reduced energy and won’t need to change your air filter as frequently. Both are savings that can build up throughout the year, so you’ll have to consider what’s best for your household.
