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

July 16, 2020

During the hot weather, running your air conditioning can be your highest monthly utility cost. So, it’s only natural that you’re looking for approaches to use less energy. That can entail trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit with air conditioner installation.

Regulating your air conditioning’s fan setting is a second way you can conserve money.

Your air conditioner relies on a fan to deliver the cool air it creates. You manage this fan at your thermostat by changing it to “auto,” which signifies the fan will only be on when the air conditioner is cooling. Or you can set it to “on,” which indicates it will run all the time.

Does putting your AC on “fan” save energy in Sacramento? Not necessarily. Typically, running your air conditioner’s fan all the time is going to drive up your energy bill slightly.

But it also offers a few perks (and disadvantages) 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 house, since rooms upstairs can be more hot. It’s also ideal if you have difficulties with inconsistent cooling due to hot and cold rooms.

It’s also good if one of your family members suffers from allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being circulated and purified. On the other hand, you may have to change your air filters more often.

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

Your residence may also appear more moist. Air conditioning helps manage humidity by removing moisture from the air. But if the fan is continuously going, it’s challenging for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only run when your air conditioner does. It’s good if your house always appears pleasant, whichever area you’re in.

There are a few disadvantages to using the auto setting. You could have hot and cold locations in your house and decreased air quality. This is due to the fact air isn’t always moving or being constantly filtered.

On the other hand, you’ll need a lower amount of energy and won’t need to change your air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to think over what’s ideal for your needs.
