For smaller residential applications, a 1-to-1 system connects one indoor concealed duct unit with one outdoor condensing unit, providing dedicated temperature control for individual spaces such as bedrooms, home offices, or additions.

For larger homes or multi-room applications, a 1-to-multi zone configuration allows multiple indoor units to connect with one outdoor unit, providing independent comfort control throughout different areas of the home.

This flexibility helps HVAC contractors design customized solutions while reducing installation limitations compared with traditional central duct systems.Multiple Capacity Options for Different Residential Needs
