Sureclean's name has changed to NRC. Sureclean is part of the NRC Group of companies and has been rebranded in line with the rest of the Group.

For an interim period, the existing Sureclean website will be maintained prior to full integration into the NRC website.

Please continue browsing the Sureclean website, but we also invite you to visit the NRC site to learn about the wider NRC Group offering, including Environmental and Emergency Response services.

HVAC/Duct Management

We use the latest technology and procedures and employ only extensively trained and experienced personnel for the inspection and cleaning of HVAC/Duct systems, to ensure continuous and efficient operation. 

HVAC/ Duct systems need to be inspected and cleaned regularly as part of a planned maintenance routine to maintain system efficiency and integrity and safeguard against the following hazards:

  • Poorly maintained HVAC/Duct systems contributing to poor air quality and contaminated ductwork
  • Filters and air handling units are a breeding ground for bacteria moulds and fungus
  • Accumulated dust and loose corrosion within HVAC/Duct systems which reduces efficiency and has long term impact on the integrity of the system
  • Within exhaust re-circulating systems and kitchen / galley extracts debris build-up increases the risk of fire.

Benefit from a full and comprehensive inspection, cleaning and maintenance programme 

Following a site visit (or alternatively from design drawings) we will provide a project-specific method statement.  The recommended cleaning will be carried out using the Sureclean Cobra Ductclean System in tandem with a Negative Pressure Unit (NPU) with HEPA filter. Where practical a pre and post inspection of the HVAC/Duct system will be undertaken providing accurate colour imagery for your records. Stills from footage will be included in a post-remedial report.

Why do you need to inspect and/or clean?

  • Legislation compliance - The Workplace (Health, Safety and Welfare) Regulations 1992
    impose a duty on employers to clean and maintain Mechanical Ventilation Systems.
  • Risk assessment
  • Part of an annual maintenance programme
  • Air quality complaints
  • System malfunction-leading to performance reduction
  • Check systems integrity
