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

July 16, 2020

During the summer, operating your air conditioning can be your biggest monthly utility charge. So, it’s normal that you’re checking for methods to save. That could entail trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit through air conditioner installation.

Switching your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner uses a fan to deliver the chilled air it produces. You adjust this fan at your thermostat by switching it to “auto,” which means the fan will only run when the air conditioner is operating. Or you can adjust it to “on,” which signifies it will run continuously.

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

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

Air Conditioner Fan Set to “On”

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

It’s also great if one of your family members deals with allergies, asthma or other respiratory problems. That’s because the air is constantly being circulated and filtrated. On the flip side, 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 cause the fan to wear out faster and need air conditioning repair.

Your residence may also seem muggier. Air conditioning helps balance humidity by clearing wetness from the air. But if the fan is continually going, it’s more difficult for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only go when your air conditioner does. It’s ideal if your home always appears the right temperature, whichever room you’re in.

There are a few downsides to using the auto setting. You may have hot and cold spots in your residence and lower air quality. This is due to the fact air isn’t constantly flowing or being continuously filtered.

On the other hand, you’ll need less energy and won’t be required to switch you air filter as frequently. Both are savings that can add up throughout the year, so you’ll have to consider what’s best for your needs.
