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

July 16, 2020

During the high temperatures, running your air conditioning can be your highest monthly electrical expense. So, it’s only natural that you’re seeking approaches to use less energy. That might entail trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cool air it makes. You adjust this fan at your thermostat by switching it to “auto,” which indicates the fan will only run when the air conditioner is going. Or you can set it to “on,” which means it will run all the time.

Does putting your AC on “fan” save energy in Paso Robles? Not necessarily. Usually, running your air conditioner’s fan constantly is going to increase your energy bill slightly.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better stabilize your family’s comfort. This is ideal if you own a two-story house, since rooms upstairs can be hotter. It’s also great if you have problems with inconsistent cooling on account of hot and cold rooms.

It’s also great if one of your family members suffers from allergies, asthma or other respiratory illnesses. That’s due to the fact the air is constantly being dispersed and filtered. However, you may have to switch your air filters more often.

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

Your home may also feel muggier. Air conditioning helps control humidity by clearing water from the air. But if the fan is constantly on, it’s more difficult for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

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

There are a few drawbacks to using the auto setting. You may have hot and cold spots in your home and reduced air quality. This is because air isn’t constantly being distributed or being constantly filtered.

On the flip side, you’ll consume reduced energy and won’t need to get a new 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 home.
