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

During the high temperatures, operating your air conditioning can be your largest monthly electricity charge. So, it’s given that you’re looking for ways to use less energy. That might include trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

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

Your air conditioner works with a fan to deliver the chilled air it creates. You control this fan at your thermostat by switching it to “auto,” which signifies the fan will only run when the air conditioner is going. Or you can adjust it to “on,” which signifies it will be on constantly.

Does putting your AC on “fan” save energy in Lake Worth? This isn’t always the case. Generally, running your air conditioner’s fan all day is going to increase your energy bill slightly.

But it also provides a few advantages (and downsides) when it comes 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 home’s comfort. This is ideal if you live in a two-story home, since spaces upstairs can be warmer. It’s also ideal if you have difficulties with unbalanced cooling due to hot and cold areas.

It’s also good if one of your family members suffers from allergies, asthma or other respiratory problems. That’s because the air is continuously being distributed and filtered. On the other hand, you may have to change your air filters more often.

Having the fan on constantly can also drive up your energy bills. It could also result in the fan wearing out more quickly and need air conditioning repair.

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

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only go when your air conditioner does. It’s ideal if your home always seems the right temperature, regardless of which spot you’re in.

There are a few downsides to using the auto setting. You might have hot and cold spots in your house and lower air quality. This is because air isn’t always moving or being repeatedly filtered.

On the flip side, you’ll need less energy and won’t have to change your air filter as frequently. Both are savings that can tally up over the year, so you’ll have to think about what’s right for your family.
