Exposed architecture in commercial spaces demands HVAC solutions that are both highly functional and visually appealing. In this ongoing project, our lead technician is finalizing the installation of a massive Lennox commercial-grade air handler designed to push massive volumes of conditioned air. What makes this installation special is the rigid, galvanized spiral ductwork running elegantly along the exposed steel-truss ceiling. Spiral ductwork is highly favored in modern multi-use commercial spaces and lofty retail environments because it looks fantastic and offers superior aerodynamic airflow with significantly less pressure drop than traditional rectangular ducts. This Lennox system is equipped with advanced filtration to improve indoor air quality for employees, providing an optimal blend of industrial aesthetics and state-of-the-art cooling performance.
