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

July 16, 2020

During the hot weather, operating your air conditioning can be your biggest monthly electrical cost. So, it’s only natural that you’re seeking approaches to use less energy. That may entail trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system through air conditioner installation.

Modifying your air conditioning’s fan setting is a second way you can spend less money.

Your air conditioner works with a fan to dispatch the chilled air it makes. You manage this fan at your thermostat by changing it to “auto,” which indicates the fan will only be on when the air conditioner is cooling. Or you can adjust it to “on,” which indicates it will operate constantly.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all the time can better balance your house’s comfort. This is ideal if you own a two-story house, since spaces upstairs can be hotter. It’s also ideal if you struggle with uneven cooling because of hot and cold rooms.

It’s also great if one of your family members has allergies, asthma or other respiratory issues. That’s since the air is constantly being circulated and purified. On the other hand, you may have to change your air filters more frequently.

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

Your residence may also feel more humid. Air conditioning helps balance humidity by extracting water from the air. But if the fan is constantly running, it’s harder for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only go when your air conditioner does. It’s ideal if your house always feels comfy, regardless of which spot you’re in.

There are a few drawbacks to using the auto setting. You might have hot and cold spots in your house and lower air quality. This is because air isn’t constantly moving or being continuously filtrated.

On the flip side, you’ll require a lower amount of energy and won’t have to replace your air filter as frequently. Both are savings that can build up throughout the year, so you’ll have to think over what’s ideal for your home.
