How does a ductless heat pump work?
Ductless heat pumps are reversible, 2-way heat pumps that use electricity to transfer heat between outdoor and indoor air by compressing and expanding a refrigerant. Using a refrigerant vapor compression cycle, like a common household refrigerator, ductless heat pumps collect heat from outside the house and deliver it inside on the heating cycle, and vise versa on the cooling cycle.
