HVAC trim out refers to the process of installing the final components of an HVAC system, such as registers, grilles, diffusers, and thermostats, after the primary ductwork and mechanical equipment have been installed. This stage typically occurs after the walls have been finished and painted, allowing for a clean and seamless appearance.
