This is the oversight of Heating, Ventilation, and Air Conditioning (HVAC) systems within facilities. It encompasses regular maintenance and repair of system components, operational monitoring for optimal performance, ensuring adherence to relevant standards and regulations, strategising for energy efficiency, managing budgets, coordinating with technical staff, and preparing for potential emergencies. The primary objective is to guarantee comfortable, safe, and efficient indoor environments through a systematic and coordinated approach.

This typically falls to Facilities Managers or HVAC Managers within an organisation or facility. They oversee the regular inspection, repair, and upkeep of HVAC systems, ensuring optimal performance and compliance with standards. In larger setups, a dedicated HVAC maintenance team supports these managers, handling specific tasks and repairs. In smaller establishments, the building owner or administrative staff might directly oversee HVAC maintenance. External contractors can also be engaged for specialised tasks or routine service checks. Regardless of the structure, the primary goal is to ensure a consistent, safe, and efficient climate-controlled environment.
