Efficiency of Ductless Split a/c

8 years ago

I have been reading about these systems and comparing them with Central Air. From my research, they offer savings in the following ways:

  • 30% saving in ducting heat loss
  • variable speed
  • ability to only heat/cool rooms in use
  • 350% efficiency: I read that these systems generate upto 3.5 units of heat for every unit of energy consumed

Can someone confirm if these benefits are actually realized? If so, these systems appear to be extremely efficient. Why are they not replacing Central Air still in new constructions?
