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

During the hot weather, using your air conditioning can be your highest monthly electrical charge. So, it’s normal that you’re seeking approaches to use less energy. That may involve trying an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model through air conditioner installation.

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

Your air conditioner works with a fan to distribute the chilled air it creates. You control this fan at your thermostat by changing it to “auto,” which means the fan will only work when the air conditioner is operating. Or you can switch it to “on,” which signifies it will work all the time.

Does putting your AC on “fan” save energy in Denton? Not necessarily. Usually, running your air conditioner’s fan constantly is going to increase your energy bill slightly.

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

Air Conditioner Fan Set to “On”

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

It’s also beneficial if one of your loved ones deals with allergies, asthma or other respiratory symptoms. That’s due to the fact the air is constantly being circulated and purified. On the flip side, you may have to switch your air filters more frequently.

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

Your residence may also appear muggier. Air conditioning helps control humidity by removing moisture from the air. But if the fan is continuously running, it’s harder for moisture to drain from the condenser outdoors.

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 great if your residence always seems the right temperature, whichever area you’re in.

There are a few disadvantages to using the auto setting. You may experience hot and cold spots in your residence and decreased air quality. This is due to the fact air isn’t constantly moving or being repeatedly filtered.

On the other hand, you’ll need a lower amount of energy and won’t have to replace your air filter as frequently. Both are savings that can add up throughout the year, so you’ll have to think about what’s ideal for your family.
