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

July 16, 2020

During the high temperatures, using your air conditioning can be your highest monthly electricity charge. So, it’s given that you’re checking for methods to consume less energy. That could entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system with air conditioner installation.

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

Your air conditioner works with a fan to dispatch the cool air it makes. You control this fan at your thermostat by setting it to “auto,” which indicates the fan will only be on when the air conditioner is operating. Or you can set it to “on,” which means it will be on all the time.

Does putting your AC on “fan” save energy in Montoursville? Not always. Usually, running your air conditioner’s fan all the time is going to make your energy bill slightly higher.

But it also provides a few pluses (and downsides) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better balance your house’s comfort. This is good if you live in a two-story residence, since areas upstairs can be more hot. It’s also good if you have issues with inconsistent cooling due to hot and cold rooms.

It’s also beneficial if someone in your household suffers from allergies, asthma or other respiratory illnesses. That’s due to the fact the air is constantly being circulated and filtrated. On the other hand, you may have to switch your air filters more often.

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

Your home may also seem muggier. Air conditioning helps balance humidity by drawing wetness from the air. But if the fan is always going, it’s challenging for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only run when your air conditioner does. It’s good if your residence always feels comfortable, whichever area you’re in.

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

On the flip side, you’ll use less energy and won’t have to replace your air filter as often. Both are savings that can tally up over the year, so you’ll have to think about what’s ideal for your household.
