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

July 16, 2020

During the hot weather, using your air conditioning can be your largest monthly electricity charge. So, it’s normal that you’re seeking approaches to consume less energy. That could entail using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated system during air conditioner installation.

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

Your air conditioner uses a fan to deliver the cold air it creates. You control this fan at your thermostat by changing it to “auto,” which means the fan will only work when the air conditioner is working. Or you can switch it to “on,” which signifies it will operate all the time.

Does putting your AC on “fan” save energy in York? Not always. Usually, using your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also provides a few advantages (and drawbacks) when it comes to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better stabilize your house’s comfort. This is good if you own a two-story house, since rooms upstairs can be hotter. It’s also ideal if you have difficulties with uneven cooling due to hot and cold spaces.

It’s also beneficial if one of your family members deals with allergies, asthma or other respiratory issues. That’s since the air is consistently being distributed and filtrated. On the other hand, you may have to switch your air filters more often.

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

Your house may also feel muggier. Air conditioning helps manage humidity by clearing moisture from the air. But if the fan is constantly running, it’s more difficult for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

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

There are a few downsides to using the auto setting. You could experience hot and cold areas in your home and decreased air quality. This is due to the fact air isn’t continuously flowing or being repeatedly filtered.

That said, you’ll use a lower amount of energy and won’t need to replace your air filter as regularly. Both are savings that can tally up during the year, so you’ll have to think over what’s ideal for your needs.
