This Mini-split diagram depicts heating and cooling systems that allow you to control the temperature in specific rooms or spaces. Mini-split systems are two major parts: an outdoor compressor/condenser and an indoor air-handling unit(s) (evaporator). Mini-split heat pumps are excellent for whole-house or new construction applications. Still, they also make perfect retrofit additions to homes with non-ducted heating systems such as hydronic, radiant panels, and space heaters (wood, kerosene, propane). They're also good for room additions where extending or installing distribution ductwork isn't an option, as shown in the mini-split diagram.
