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

July 16, 2020

During the hot weather, using your air conditioning can be your biggest monthly electrical charge. So, it’s only natural that you’re looking for approaches to use less energy. That may include finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit through air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cold air it makes. You manage this fan at your thermostat by switching it to “auto,” which indicates the fan will only work when the air conditioner is cooling. Or you can set it to “on,” which signifies it will work all the time.

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

But it also has a few perks (and disadvantages) as far as your residence’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 have a two-story home, since spaces upstairs can be hotter. It’s also ideal if you have problems with inconsistent cooling because of hot and cold spaces.

It’s also advantageous if someone in your household has allergies, asthma or other respiratory problems. That’s because the air is consistently being dispersed and filtered. On the other hand, you may have to change your air filters more regularly.

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

Your residence may also appear muggier. Air conditioning helps manage humidity by extracting water from the air. But if the fan is continually on, it’s challenging for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only run when your air conditioner does. It’s ideal if your house always appears pleasant, regardless of which spot you’re in.

There are a few downsides to using the auto setting. You could run into hot and cold locations in your residence and decreased air quality. This is due to the fact air isn’t constantly moving or being constantly filtrated.

On the other hand, you’ll consume reduced energy and won’t have to change your air filter as regularly. Both are savings that can build up over the year, so you’ll have to think over what’s best for your home.
