A SMS Environmental engineer servicing HVAC Air Handling systems maintenance

With many organisations now controlling internal environments through HVAC systems, a fully maintained HVAC system is essential to ensure the efficiency and safe operation of plant, as well as providing clean air, which is fundamental for the health and well-being of the building occupants.


Indoor air quality is influenced by two major components: the amount and quality of outdoor air getting in and indoor sources of pollutant emissions.


A sustainable environment is a common theme in many organisations’ strategy plans with the objectives of efficiently managing energy usage and facilitating carbon emission reduction in buildings.
