How do they work?

Ductless heat pumps provide heat by extracting heat from outside air and delivering it indoors as needed. Because they are moving heat, rather than generating it through combustion or resistance, heat pumps can achieve efficiencies well above 100%. Long used for cooling in warm climates, heat pumps are now able to provide efficient heating in cold climates even at outdoor temperatures as low as -15 °F.

Ductless heat pumps consist of an outdoor unit connected to indoor air handlers by refrigerant lines, which carry heat between the two units. There are four types of indoor units:
