Like any other heat pump, ductless heat pumps are based on a reversible cooling cycle. In a standard air conditioner, liquid refrigerant chemicals absorb heat at the evaporator coil, become gaseous, travel to the condenser coil and release that stored heat as they become liquid again. The cycle literally pumps heat out of the home. Heat pumps use the same cycle, but they can run in either direction to pump heat into or out of the house as needed. The result is efficient heating and cooling throughout the year.
Ductless air conditioners and heat pumps use the same basic cycle as standard air conditioners and heat pumps, but they offer several key advantages. When doing a ductless AC vs. central AC vs. window unit comparison, keep these factors in mind:
The up-front cost of going ductless does tend to be a little higher than the cost of central air. However, the energy savings alone are enough to offset that cost over time. Ductless systems are particularly worthwhile for smaller homes, apartments and condominiums, and because there's no need to extend the duct system to accommodate the unit, they're often the most cost-effective option for new additions.
