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

July 16, 2020

During the summer, using your air conditioning can be your highest monthly electricity cost. So, it’s only natural that you’re looking for ways to save. That may entail trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model through 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 distribute the cool air it makes. You manage this fan at your thermostat by setting it to “auto,” which signifies the fan will only work when the air conditioner is running. Or you can switch it to “on,” which indicates it will operate continuously.

Does putting your AC on “fan” save energy in Boynton Beach? Not necessarily. Typically, using your air conditioner’s fan all the time 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 go all day can better balance your family’s comfort. This is great if you have a two-story house, since spaces upstairs can be warmer. It’s also good if you have problems with uneven cooling on account of hot and cold spaces.

It’s also beneficial if one of your family members has allergies, asthma or other respiratory symptoms. That’s because the air is continuously being circulated and purified. On the flip side, you may have to put in new air filters more often.

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

Your house may also appear more moist. Air conditioning helps balance humidity by removing water from the air. But if the fan is always running, it’s harder for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

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

There are a few downsides to using the auto setting. You could run into hot and cold spots in your house and decreased air quality. This is since air isn’t constantly being distributed or being constantly filtrated.

On the other hand, you’ll require less energy and won’t need to get a new air filter as regularly. Both are savings that can tally up throughout the year, so you’ll have to think about what’s ideal for your household.
