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

July 16, 2020

During the high temperatures, operating your air conditioning can be your highest monthly electricity charge. So, it’s only natural that you’re looking for ways to save. That could involve finding an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated system during air conditioner installation.

Regulating your air conditioning’s fan setting is an additional way you can save money.

Your air conditioner works with a fan to dispatch the cool air it produces. You control this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is running. Or you can set it to “on,” which indicates it will be on constantly.

Does putting your AC on “fan” save energy in Bend? Not always. Typically, operating your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also has a few pluses (and disadvantages) in relation to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better balance your house’s comfort. This is good if you live in a two-story residence, since rooms upstairs can be more hot. It’s also ideal if you have problems with inconsistent cooling on account of hot and cold areas.

It’s also great if someone in your household has been diagnosed with allergies, asthma or other respiratory problems. That’s because the air is consistently being distributed and purified. On the other hand, you may have to install new air filters more regularly.

Having the fan on all the time can also drive up your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

Your house may also feel more moist. Air conditioning helps manage humidity by drawing water from the air. But if the fan is continually working, it’s challenging for moisture to drain from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only operate when your air conditioner does. It’s great if your residence always seems cool, whichever spot you’re in.

There are a few downsides to using the auto setting. You may experience hot and cold areas in your residence and decreased air quality. This is since air isn’t continuously moving or being constantly purified.

On the flip side, you’ll consume reduced energy and won’t need to get a new air filter as frequently. Both are savings that can add up over the year, so you’ll have to think over what’s ideal for your needs.
