The answer to 'what is ductless system' is a type of HVAC system that does not require ductwork to distribute conditioned air throughout a home. Ductless systems, also known as mini-split systems, use individual wall-mounted indoor units connected to an outdoor compressor unit by refrigerant lines. This allows for zoned temperature control, where each indoor unit can be set to a different temperature, providing flexibility and energy efficiency.
Ductless systems are a popular choice for homes without existing ductwork, additions, or spaces that are difficult to condition with traditional HVAC systems. They are typically easier to install than a full central air system and can provide heating and cooling to specific areas of a home.
