Mini-splits are heating and cooling systems that let you control the temperature in each room separately.

They have two main parts: an outdoor unit and one or more indoor units. Installation is easy and usually only needs a small hole in the wall for the cables and pipes that connect the two units.

Mini-split heat pumps work well for both whole homes and new buildings. They are also a good option for adding to houses that don’t have ducts, like those with hot water heat, radiant panels, or space heaters. Mini-splits are also great for room additions where it’s hard to add ductwork, or for energy-efficient homes that don’t need a big heating or cooling system.
