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

July 16, 2020

During the summer, operating your air conditioning can be your highest monthly utility charge. So, it’s only natural that you’re checking for ways to consume less energy. That could involve trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

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

Your air conditioner relies on a fan to dispatch the cool air it makes. You manage this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is going. Or you can set it to “on,” which signifies it will run all the time.

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

But it also offers a few advantages (and disadvantages) as far as your residence’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 home’s comfort. This is ideal if you live in a two-story residence, since areas upstairs can be hotter. It’s also great if you have issues with unbalanced cooling on account of hot and cold spots.

It’s also beneficial if someone in your household suffers from allergies, asthma or other respiratory problems. That’s because the air is constantly being circulated and filtered. However, you may have to switch your air filters more regularly.

Having the fan on constantly can also increase your energy bills. It could also cause the fan to wear out prematurely and need air conditioning repair.

Your residence may also feel more moist. Air conditioning helps balance humidity by extracting water from the air. But if the fan is constantly working, it’s challenging for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only run when your air conditioner does. It’s good if your house always appears comfy, no matter what area you’re in.

There are a few drawbacks to using the auto setting. You could have hot and cold spots in your house and reduced air quality. This is due to the fact air isn’t continuously flowing or being continuously filtered.

That said, you’ll need a lower amount of energy and won’t be required to get a new air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to think about what’s best for your household.
