What’s the Difference Between a Ductless and Ducted Mini Split?
A ducted mini split uses hidden ducts to distribute air throughout your home, similar to a traditional central HVAC system but on a smaller scale. It provides a clean look with no visible indoor units but requires space for ductwork and is best for new builds or major remodels.
A ductless mini split, on the other hand, has one or more wall-, floor-, or ceiling-mounted indoor units that connect directly to the outdoor unit—no ductwork needed. It’s easier to install, more energy-efficient, and ideal for older homes, room additions, or areas where ducting isn’t practical.
