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

July 16, 2020

During the high temperatures, operating your air conditioning can be your highest monthly electrical charge. So, it’s normal that you’re checking for methods to consume less energy. That may include using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model through air conditioner installation.

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

Your air conditioner relies on a fan to deliver the cold air it creates. You manage this fan at your thermostat by setting it to “auto,” which means the fan will only run when the air conditioner is working. Or you can switch it to “on,” which signifies it will be on all the time.

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

But it also gives a few perks (and drawbacks) when it comes to your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better balance your home’s comfort. This is ideal if you live in a two-story house, since rooms upstairs can be more hot. It’s also great if you have problems with uneven cooling because of hot and cold spaces.

It’s also advantageous if someone in your household has been diagnosed with allergies, asthma or other respiratory issues. That’s since the air is consistently being circulated and filtrated. On the other hand, you may have to put in new air filters more frequently.

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

Your residence may also feel more moist. Air conditioning helps manage humidity by clearing water 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, since the fan will only operate when your air conditioner does. It’s ideal if your residence always appears pleasant, regardless of which area you’re in.

There are a few downsides to using the auto setting. You could run into hot and cold spots in your residence and lower air quality. This is due to the fact air isn’t constantly flowing or being continuously filtered.

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