Which type of HVAC system is characterized as "ductless"?

The mini-split system is identified as "ductless" due to its design, which allows for the distribution of conditioned air without the need for traditional ductwork. Mini-split systems consist of two main components: an outdoor unit, which houses the compressor and condenser, and one or more indoor units that effectively disperse the air directly into the living spaces.

This ductless feature provides several benefits, including improved energy efficiency, as it reduces the energy loss associated with ductwork and allows for zoned heating or cooling. Furthermore, mini-split systems are versatile and can be installed in areas where traditional HVAC systems may not be feasible or practical, such as older buildings or spaces that require retrofitting.

Understanding this design is crucial for HVAC professionals, as it not only influences installation practices but also impacts the overall efficiency and performance of the heating and cooling systems in various applications.
