Damper Ducted Systems: These systems use dampers installed within the ductwork to control and direct airflow to specific zones. While they offer zone control in ducted HVAC systems, their effectiveness depends on the proper adjustment of ductwork and blower size. It's essential to ensure that these systems are meticulously designed and balanced to avoid issues like uneven heating/cooling and system strain.
Ductless Systems: Ductless zone control systems, often referred to as mini-split systems, offer a more flexible and efficient approach to zoning, especially advantageous in new constructions. Each zone has its own independent unit, eliminating the need for ductwork and allowing precise temperature control. Ductless systems are easier to install, offer higher energy efficiency, and provide a more direct approach to heating and cooling specific areas of a building.
