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

July 16, 2020

During the high temperatures, operating your air conditioning can be your biggest monthly utility expense. So, it’s normal that you’re seeking methods to consume less energy. That can entail using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner relies on a fan to deliver the cold air it makes. You manage this fan at your thermostat by setting it to “auto,” which means the fan will only work when the air conditioner is operating. Or you can set it to “on,” which indicates it will operate continuously.

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

But it also offers a few advantages (and drawbacks) when it comes to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better balance your home’s comfort. This is great if you have a two-story residence, since areas upstairs can be more hot. It’s also great if you have difficulties with uneven cooling on account of hot and cold spots.

It’s also good if someone in your household suffers from allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being circulated and filtrated. On the flip side, you may have to change your air filters more regularly.

Having the fan on all the time can also increase your energy bills. It could also result in the fan wearing out sooner and need air conditioning repair.

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

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 house always appears pleasant, no matter what area you’re in.

There are a few downsides to using the auto setting. You may experience hot and cold spots in your home and decreased air quality. This is due to the fact air isn’t always flowing or being constantly purified.

On the other hand, you’ll use reduced energy and won’t need to replace your air filter as often. Both are savings that can tally up over the year, so you’ll have to think over what’s right for your needs.
