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

July 16, 2020

During the summer, using your air conditioning can be your biggest monthly electricity cost. So, it’s given that you’re checking for approaches to save. That may entail finding an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated unit during air conditioner installation.

Regulating your air conditioning’s fan setting is a second way you can spend less money.

Your air conditioner works with a fan to distribute the chilled air it produces. You control this fan at your thermostat by switching it to “auto,” which means the fan will only be on when the air conditioner is going. Or you can switch it to “on,” which indicates it will be on all the time.

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

But it also offers a few perks (and downsides) in relation 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 house’s comfort. This is great if you own a two-story residence, since areas upstairs can be more hot. It’s also good if you struggle with inconsistent cooling on account of hot and cold areas.

It’s also beneficial if one of your family members deals with allergies, asthma or other respiratory symptoms. That’s because the air is consistently being distributed and purified. On the flip side, you may have to install new air filters more often.

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

Your home may also appear more humid. Air conditioning helps balance humidity by removing wetness from the air. But if the fan is continually running, it’s challenging for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only operate when your air conditioner does. It’s good if your residence always feels comfortable, no matter what spot you’re in.

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

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