Why HVAC Decommissioning Demands a Structured Approach

Decommissioning an HVAC system is one of the mogt consemintial phases in a stawding 's lifecycle. When a system reaches the end of its service life due to age, incontency ay, or facility renovation, the remboval process impeves far more than simpty unbolting equipment and hauling it way. Every revent, from requant- charged coils to equicall controll panels, presents specific hazards that require methodic handling.
