Air Handling Unit Cleaning

Air handling unit (AHU) cleaning is essential for maintaining good indoor air quality and ensuring efficient HVAC system operation. Regular cleaning removes dust, debris, and contaminants that can accumulate in the unit’s components, such as filters, coils, and ducts. This helps prevent the spread of pathogens, reduces the risk of breakdowns, and improves overall system performance.

Why is AHU cleaning important?

  • Improved indoor air quality: AHU cleaning removes dust, allergens, and other pollutants that can negatively impact air quality and potentially cause respiratory issues.
  • Enhanced HVAC system efficiency: Clean components allow for better airflow, reducing the strain on the system and improving its energy efficiency.
  • Reduced risk of breakdowns: Regular cleaning and maintenance can identify potential problems early, preventing costly repairs and downtime.
  • Compliance with health and safety standards: Many regulations require maintaining a clean and healthy working environment, which includes proper HVAC system maintenance.
  • Prevention of mould and bacterial growth: AHU components, especially coils and drain pans, can be breeding grounds for mould and bacteria. Regular cleaning and disinfection are crucial to prevent their spread.

What does AHU cleaning involve?

  • Filter replacement and cleaning: Filters should be checked and replaced regularly.
  • Coil cleaning: Coils, which transfer heat, should be cleaned to remove dust and debris that can hinder their performance.
  • Duct cleaning: Ducts can accumulate dust and contaminants that can circulate throughout the building.
  • Drain pan and line cleaning: Drain pans and lines should be cleaned to prevent the buildup of bacteria and mould.
  • Fan and interior cleaning: Fans and the interior surfaces of the AHU should be cleaned to remove dust and debris.
