Which is more energy efficient Central AC or locational AC?
For example in a modern single story 2000 Sq. Ft. house with outdoor openings properly sealed and using recent AC technology, I wonder which is better? While it may be natural to think locational AC is better, I am debating if it would be constantly fighting with neighboring rooms where AC is not running, as opposed to Central AC, which can equalize the whole house.

Energy efficient.... central air. One unit cools the whole house'
I think the first 2 answers you got are based on guesses. I don't know how to figure this out. Have you call your local electric company. They probably have the answer & please come back & let us all know.
My central A/c broke & I paid $300 to have it repaired & it still didn't work well. I live in a 2400 sq. foot house & I am usually home alone each day. When I was younger I wanted to clean the whole house & be free to go anywhere in the house & now I stay in one place most of the time. So I use window unity. My electric bills seems low but it could also be that I have not had to run it as much so I am not sure how to give you an accurate answer.
I do think the electric co could tell you how much it cost to run each unit but it would not be able to tell how that works with you lifestyle & your house.
I sit in my living room & the ac in the dinning room keeps me cool. My downstairs is open but the cool air stays up here.
If you keep the door closed on your single room, no problem.
The nice thing about central AC is that it lowers the humidity in the house, which can contribute as much or more to your comfort than just blowing cold air.
A mandatory plant is very almost consistently extra fee-effective, if that's designed and operated wisely. mandatory structures could have water cooled contraptions, that are critically extra efficient, and - when you consider that they typically have distinctive contraptions - can experience their potential to the burden. So, rather of working inefficiently numerous the 300 and sixty 5 days (whilst plenty are actually not at their height), which a transportable unit would desire to do, the mandatory plant could use a smaller form of contraptions working at a miles better and extra efficient load ingredient. frequently used numbers are a million.25 kW/ton for transportable contraptions and below a million kW/ton for a compulsory plant (even an older one). extra present day structures, with variable speed pumping and head stress administration get right down to 0.5 - 0.6 kW/ton. And, with a compulsory plant, that's going to become extra achievable to place in loose cooling structures.
Will the central AC increase the value of your home? Probably, so the cost of running it and the difference in monthly cost may be secondary. How many people live in the home?
No, if you only keep one room cool, it's definitely cheaper to cool one room like a bedroom.
EDIT:...This is not a guess. I've done both.
