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

July 16, 2020

During the summer, using your air conditioning can be your highest monthly utility expense. So, it’s given that you’re checking for methods to consume less energy. That could include using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated system with air conditioner installation.

Adjusting your air conditioning’s fan setting is another way you can save money.

Your air conditioner uses a fan to deliver the chilled air it produces. You control this fan at your thermostat by changing it to “auto,” which signifies the fan will only be on when the air conditioner is running. Or you can set it to “on,” which signifies it will be on continuously.

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

But it also offers a few advantages (and drawbacks) 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 balance your home’s comfort. This is great if you have a two-story home, since spaces upstairs can be more hot. It’s also ideal if you have difficulties with inconsistent cooling due to hot and cold spots.

It’s also beneficial if one of your family members has allergies, asthma or other respiratory problems. That’s due to the fact the air is continuously being circulated and filtrated. On the other hand, you may have to replace your air filters more frequently.

Having the fan on all day can also drive up your energy bills. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your residence may also appear more humid. Air conditioning helps manage humidity by extracting wetness from the air. But if the fan is continually on, it’s harder for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only run when your air conditioner does. It’s great if your residence always seems the right temperature, no matter what room you’re in.

There are a few drawbacks to using the auto setting. You could experience hot and cold areas in your home and reduced air quality. This is since air isn’t constantly being distributed or being constantly filtered.

On the other hand, you’ll need reduced energy and won’t have to get a new air filter as frequently. Both are savings that can tally up over the year, so you’ll have to consider what’s best for your household.
