HVAC (Heating, Ventilation, and Air Conditioning) systems are related to building systems, and a professional who deals with HVAC and building systems, especially when there's a structural stability threat, an HVAC technician or a mechanical engineer (but more specifically, an HVAC professional or a mechanical engineer with HVAC expertise; however, in the context of building systems and HVAC replacement, an HVAC technician or a mechanical engineer, but the most relevant here is an HVAC technician or a mechanical engineer, but the key is that the professional who handles HVAC system replacement and related building system issues is an HVAC technician or a mechanical engineer. Wait, actually, for HVAC system replacement and inspection, the professional is an HVAC technician (or HVAC engineer).
