Upgrading a rooftop HVAC system doesn’t have to mean expensive roof modifications. A custom curb adapter provides a seamless solution by allowing new HVAC units to fit directly onto existing curbs. Designed to align airflow, support the unit, and speed up installation, curb adapters save time, reduce costs, and boost energy efficiency. At HVACDirect.com, we make it simple—just share your unit details, approve the drawings, and get a custom-built adapter ready to install.
