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

July 16, 2020

During the hot weather, operating your air conditioning can be your biggest monthly utility expense. So, it’s normal that you’re checking for methods to use less energy. That may entail using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

Modifying your air conditioning’s fan setting is another way you can save money.

Your air conditioner uses a fan to dispatch the cold air it makes. You adjust this fan at your thermostat by changing it to “auto,” which signifies the fan will only be on when the air conditioner is working. Or you can set it to “on,” which signifies it will operate constantly.

Does putting your AC on “fan” save energy in Florissant? This isn’t always the case. Generally, running your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also has a few perks (and downsides) as far as your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better equalize your house’s comfort. This is great if you have a two-story residence, since rooms upstairs can be more hot. It’s also great if you have issues with uneven cooling due to hot and cold areas.

It’s also advantageous if one of your family members suffers from allergies, asthma or other respiratory problems. That’s due to the fact the air is continuously being circulated and filtered. However, you may have to change your air filters more frequently.

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

Your house may also feel more moist. Air conditioning helps control humidity by extracting water from the air. But if the fan is continually on, it’s harder for moisture to drip from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, since the fan will only go when your air conditioner does. It’s ideal if your residence always seems comfy, no matter what spot you’re in.

There are a few disadvantages to using the auto setting. You might experience hot and cold locations in your house and reduced air quality. This is since air isn’t continuously flowing or being constantly filtered.

On the flip side, you’ll use a lower amount of energy and won’t need to change your air filter as frequently. Both are savings that can build up during the year, so you’ll have to think over what’s best for your family.
