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

July 16, 2020

During the high temperatures, using your air conditioning can be your largest monthly utility charge. So, it’s only natural that you’re looking for methods to save. That might involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit during air conditioner installation.

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

Your air conditioner works with a fan to distribute the chilled air it makes. You control this fan at your thermostat by changing it to “auto,” which indicates the fan will only be on when the air conditioner is working. Or you can switch it to “on,” which indicates it will operate continuously.

Does putting your AC on “fan” save energy in West Jefferson? This isn’t always the case. Generally, running your air conditioner’s fan all the time is going to increase your energy bill slightly.

But it also gives a few advantages (and disadvantages) in regard to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go all day can better stabilize your home’s comfort. This is great if you live in a two-story house, since rooms upstairs can be more hot. It’s also good if you have issues with unbalanced cooling on account of hot and cold areas.

It’s also great if one of your loved ones deals with allergies, asthma or other respiratory problems. That’s since the air is constantly being circulated and filtrated. However, you may have to change your air filters more often.

Having the fan on all day can also make your energy bills more expensive. It could also result in the fan wearing out more quickly and need air conditioning repair.

Your house may also appear muggier. Air conditioning helps manage humidity by removing wetness from the air. But if the fan is constantly going, it’s challenging for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

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

There are a few disadvantages to using the auto setting. You might run into hot and cold areas in your house and lower air quality. This is because air isn’t continuously being distributed or being constantly filtered.

On the flip side, you’ll require a lower amount of energy and won’t need to change your air filter as regularly. Both are savings that can tally up over the year, so you’ll have to consider what’s best for your needs.
