Ductless minisplit vs ducted split AC systems for whole-house application
I’ve read about a builder in NC that uses ductless minisplits in a whole-house new construction application. What are your thoughts and commentary about such an application?
To run refrigerant tubing vs. a potentially leaky duct even in the conditioned space would seem to be preferable. Not to mention the zoning advantages and conditioning occupied space vs conditioning unoccupied rooms in a non zoned split a/c or h/p system.
Would the house design have to be less flexible? For example I think most minisplits’ minimum is 9,000 BTU. That seems more BTUs than needed for most bedrooms. Also I would think that the design could not have a hallway. Traditional split a/c systems with duct work still seems primitive.
I live in southeast Alabama, a hot and humid climate.
