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

During the summer, running your air conditioning can be your biggest monthly electricity expense. So, it’s only natural that you’re checking for approaches to use less energy. That may include finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit with air conditioner installation.

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

Your air conditioner relies on a fan to dispatch the chilled air it makes. You control this fan at your thermostat by setting it to “auto,” which signifies the fan will only be on when the air conditioner is working. Or you can switch it to “on,” which means it will run constantly.

Does putting your AC on “fan” save energy in East Bernard? This isn’t always the case. Usually, using your air conditioner’s fan constantly is going to increase your energy bill slightly.

But it also offers a few perks (and downsides) as far as your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better equalize your family’s comfort. This is good if you own a two-story home, since areas upstairs can be more hot. It’s also ideal if you struggle with unbalanced cooling because of hot and cold spots.

It’s also advantageous if one of your family members has been diagnosed with allergies, asthma or other respiratory illnesses. That’s because the air is consistently being circulated and filtered. However, you may have to replace 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 more quickly and need air conditioning repair.

Your home may also feel more humid. Air conditioning helps manage humidity by removing moisture from the air. But if the fan is always on, it’s harder for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only run when your air conditioner does. It’s good if your house always seems comfy, regardless of which spot you’re in.

There are a few disadvantages to using the auto setting. You could experience hot and cold areas in your residence and lower air quality. This is because air isn’t constantly being distributed or being constantly purified.

On the other hand, you’ll use reduced energy and won’t need to get a new air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to consider what’s best for your family.
