Air Duct Cleaning

Clean Air Technology at Work

Air ducts and Air Handling Plant can become contaminated with dust, fibres and microbial contaminants if not properly maintained.

EU directives state that “mechanical ventilation systems including air conditioning systems, should be regularly and properly cleaned, tested and maintained to ensure they are kept clean and free from anything that may contaminate the air.”

It is a legal requirement to keep air handling plants and ducts clean.

Poor Ventilation Hygiene Costs

Poor ventilation hygiene occurs when an air handling plant and fans are not properly maintained and systems are not adequately filtered, used improperly and poorly designed.

Expensive Results of Poor Ventilation Hygiene;

  • Increased staff absenteeism and reduced productivity.
  • Poor Building Energy Rating as a result of inefficient operation of HVAC plant.
  • Blocked heat exchangers causing poor heat transfer and excessive energy consumption on heating equipment and fan motors due to poor heat transfer and high pressure drops.
  • Blocked return and extract ducts reduce the Air Change Rates in the building leading to increased levels of particulates, chemicals and odours.
  • Huge additional costs due to HVAC system inefficiencies, increased maintenance downtime and staff productivity.

 

HVAC System Maintenance

Once your HVAC system is clean, Enviro can maintain the AHU’s fans and ductwork systems to ensure your plant stays operating in a clean, efficient manner. We can maintain your plant as follows:

  • Supply and installation of filters.
  • Belt replacement for motor and fan drives.
