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

July 16, 2020

During the hot weather, using your air conditioning can be your largest monthly utility expense. So, it’s normal that you’re looking for approaches to use less energy. That may entail trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit with air conditioner installation.

Modifying your air conditioning’s fan setting is an additional way you can save money.

Your air conditioner works with a fan to deliver the cold air it makes. You adjust this fan at your thermostat by changing it to “auto,” which indicates the fan will only run when the air conditioner is running. Or you can switch it to “on,” which signifies it will be on constantly.

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

But it also provides a few advantages (and drawbacks) in regard to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better equalize your home’s comfort. This is ideal if you have a two-story home, since areas upstairs can be hotter. It’s also ideal if you have issues with unbalanced cooling because of hot and cold areas.

It’s also beneficial if one of your loved ones suffers from allergies, asthma or other respiratory issues. That’s due to the fact the air is continuously being circulated and purified. On the other hand, you may have to switch your air filters more regularly.

Having the fan on all the time can also drive up your energy bills. It could also make the fan wear out sooner and need air conditioning repair.

Your residence may also appear muggier. Air conditioning helps balance humidity by removing water from the air. But if the fan is continuously on, it’s challenging for moisture to flow 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 ideal if your residence always seems comfortable, whichever room you’re in.

There are a few disadvantages to using the auto setting. You may experience hot and cold locations in your home and reduced air quality. This is due to the fact air isn’t constantly being distributed or being repeatedly filtered.

On the flip side, you’ll require reduced energy and won’t need to switch you air filter as regularly. Both are savings that can add up throughout the year, so you’ll have to consider what’s right for your needs.
