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

July 16, 2020

During the high temperatures, using your air conditioning can be your biggest monthly utility charge. So, it’s only natural that you’re looking for methods to use less energy. That may involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model through air conditioner installation.

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

Your air conditioner works with a fan to distribute the cold air it creates. You manage this fan at your thermostat by changing it to “auto,” which indicates the fan will only work when the air conditioner is operating. Or you can adjust it to “on,” which means it will run constantly.

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

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate continuously can better balance your family’s comfort. This is great if you own a two-story house, since rooms upstairs can be hotter. It’s also great if you have issues with inconsistent cooling due to hot and cold rooms.

It’s also great if one of your loved ones has been diagnosed with allergies, asthma or other respiratory issues. That’s because the air is consistently being distributed and filtered. On the other hand, you may have to change your air filters more often.

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

Your house may also seem more moist. Air conditioning helps manage humidity by clearing moisture from the air. But if the fan is continuously working, it’s challenging for moisture to drain from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only operate when your air conditioner does. It’s good if your house always appears pleasant, regardless of which area you’re in.

There are a few downsides to using the auto setting. You may run into hot and cold locations in your home and reduced air quality. This is because air isn’t constantly being distributed or being continuously filtrated.

On the other hand, you’ll consume less energy and won’t be required to switch you air filter as often. Both are savings that can add up over the year, so you’ll have to think about what’s ideal for your needs.
