Ductless Mini-Split
A type of heat pump consisting of an outdoor condenser and one or more indoor air handlers connected by refrigerant lines rather than ductwork. Each indoor unit independently controls one zone.
Why It Matters
Mini-splits are the most efficient way to heat and cool specific rooms without ductwork. They are ideal for room additions, garages, or homes with no existing ducts.
