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

July 16, 2020

During the hot weather, using your air conditioning can be your largest monthly electrical expense. So, it’s normal that you’re checking for ways to use less energy. That could involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system during air conditioner installation.

Changing your air conditioning’s fan setting is a second way you can save money.

Your air conditioner uses a fan to distribute the cool air it produces. You adjust this fan at your thermostat by changing it to “auto,” which signifies the fan will only run when the air conditioner is cooling. Or you can set it to “on,” which means it will operate all the time.

Does putting your AC on “fan” save energy in Ronkonkoma? Not always. Generally, running your air conditioner’s fan all day is going to increase your energy bill slightly.

But it also gives a few advantages (and drawbacks) in relation to 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 home’s comfort. This is ideal if you have a two-story house, since areas upstairs can be more hot. It’s also good if you struggle with unbalanced cooling on account of hot and cold spots.

It’s also good if someone in your household suffers from allergies, asthma or other respiratory symptoms. That’s due to the fact the air is continuously being circulated and filtered. On the flip side, you may have to replace your air filters more frequently.

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

Your residence may also feel more moist. Air conditioning helps balance humidity by extracting moisture from the air. But if the fan is continually running, it’s challenging for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, because the fan will only work when your air conditioner does. It’s good if your house always feels comfy, regardless of which area you’re in.

There are a few downsides to using the auto setting. You could experience hot and cold locations in your home and decreased air quality. This is due to the fact air isn’t always flowing or being continuously filtered.

On the other hand, you’ll require reduced energy and won’t have to replace your air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to consider what’s ideal for your needs.
