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

July 16, 2020

During the hot weather, running your air conditioning can be your biggest monthly electricity charge. So, it’s only natural that you’re seeking ways to use less energy. That might involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

Modifying your air conditioning’s fan setting is another way you can spend less money.

Your air conditioner uses a fan to distribute the cool air it makes. You control this fan at your thermostat by changing it to “auto,” which means the fan will only run when the air conditioner is operating. Or you can switch it to “on,” which signifies it will operate all the time.

Does putting your AC on “fan” save energy in West Columbia? Not always. Usually, using your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also gives a few advantages (and downsides) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all the time can better balance your house’s comfort. This is ideal if you live in a two-story house, since rooms upstairs can be more hot. It’s also ideal if you have difficulties with unbalanced cooling due to hot and cold areas.

It’s also beneficial if one of your loved ones deals with allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being circulated and filtered. However, you may have to put in new air filters more regularly.

Having the fan on all the time can also make your energy bills more expensive. It could also cause the fan to wear out sooner and need air conditioning repair.

Your residence may also feel muggier. Air conditioning helps manage humidity by removing water from the air. But if the fan is constantly going, it’s challenging for moisture to flow 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 ideal if your house always feels pleasant, whichever room you’re in.

There are a few drawbacks to using the auto setting. You could experience hot and cold locations in your home and lower air quality. This is due to the fact air isn’t constantly flowing or being continuously filtered.

On the other hand, you’ll require a lower amount of energy and won’t need to change your air filter as often. Both are savings that can add up over the year, so you’ll have to consider what’s best for your needs.
