The answer to 'how does ductless system work' is that a ductless HVAC system, also known as a mini-split system, is a type of air conditioning and heating system that does not require the use of ductwork to distribute conditioned air throughout a home. Instead, ductless systems use individual indoor air handling units that are connected to an outdoor compressor unit by a small conduit that carries refrigerant.
Each indoor unit is responsible for cooling or heating a specific zone or room in the home, allowing for customized temperature control and energy efficiency. The indoor units are typically mounted high on the wall and have a remote control that allows the homeowner to adjust the temperature, fan speed, and other settings as needed. The outdoor compressor unit is installed on the exterior of the home and is responsible for producing the cool or warm air that is distributed to the indoor units.
