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

During the summer, running your air conditioning can be your highest monthly electrical cost. So, it’s only natural that you’re looking for approaches to use less energy. That might involve using an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation.

Switching your air conditioning’s fan setting is an additional way you can conserve money.

Your air conditioner relies on a fan to deliver the chilled air it produces. You control this fan at your thermostat by setting it to “auto,” which means the fan will only be on when the air conditioner is running. Or you can switch it to “on,” which signifies it will work continuously.

Does putting your AC on “fan” save energy in York? Not necessarily. Usually, operating your air conditioner’s fan all the time is going to increase your energy bill slightly.

But it also gives a few pluses (and downsides) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all the time can better equalize your home’s comfort. This is ideal if you have a two-story residence, since rooms upstairs can be warmer. It’s also great if you have difficulties with unbalanced cooling because of hot and cold spaces.

It’s also advantageous if one of your family members deals with allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being distributed and filtered. On the other hand, you may have to switch your air filters more frequently.

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

Your house may also appear muggier. Air conditioning helps manage humidity by extracting moisture from the air. But if the fan is continually working, it’s challenging for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, as the fan will only go when your air conditioner does. It’s great if your home always seems comfy, whichever spot you’re in.

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

On the flip side, you’ll use a lower amount of energy and won’t have to replace your air filter as often. Both are savings that can build up throughout the year, so you’ll have to think over what’s ideal for your needs.
