Ductless mini-split
A ductless mini-split is an HVAC system with individual wall-mounted indoor units connected to a single outdoor compressor, requiring no ductwork.
Why it matters
Mini-splits provide zone-by-zone temperature control and are ideal for additions, garages, or homes without existing ducts.
Where people get this wrong
Mini-splits are not window units. They are permanently installed, highly efficient, and provide both heating and cooling.
Real-world example
You finish the bonus room above the garage. Instead of extending the existing ductwork, a single mini-split unit heats and cools the space independently.
Where this hits your build
This affects daily comfort in every room. Problems often show up after move-in when certain rooms run hot, cold, or noisy.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
