A ductless heating and cooling system, frequently employing a heat pump, offers zoned temperature control without the need for extensive ductwork. These systems are comprised of an outdoor compressor/condenser and one or more indoor air-handling units, connected by refrigerant lines and electrical wiring. This configuration allows for independent climate management in individual rooms or zones.
The utilization of these systems can lead to improved energy efficiency compared to traditional central air systems, as they eliminate duct losses and allow for targeted heating or cooling. Furthermore, their relatively simple installation process makes them a viable option for retrofitting existing structures or supplementing existing HVAC systems. Their development represents a move towards more localized and adaptable climate control solutions.
