Why HVAC Duct Cleaning Matters
Your HVAC system is the lungs of your building. Every day, it distributes conditioned air across offices, warehouses, hospitals, schools, and homes. Over time, dust, dirt, and airborne contaminants accumulate within the ductwork. Without proper cleaning, this build-up can:
- Compromise indoor air quality, causing respiratory problems, allergies, or asthma.
- Reduce system efficiency, leading to higher energy bills.
- Increase fire risks by allowing grease and debris to gather in ventilation systems.
- Breach compliance with industry standards and health regulations.
Clean Air 24 Seven provides specialist HVAC duct cleaning services designed to eliminate contaminants at the source, ensuring ducts are hygienic, energy-efficient, and safe.
Compliance with NAAD21 and TR19 Air
As a trusted provider, we follow strict compliance frameworks to deliver consistent, measurable results.
NAAD21 Standards – The National Association of Air Duct Specialists (NAAD21) framework is recognised as the leading benchmark for professional duct cleaning in the UK. NAAD21 sets rigorous requirements for training, procedures, and reporting, ensuring that duct cleaning is not only thorough but also transparent. Our technicians are trained and certified in NAAD21 protocols, giving our clients confidence in the quality and accountability of every project.
TR19 Air Guidelines – TR19 Air, published by BESA (Building Engineering Services Association), is the definitive standard for the cleanliness of ventilation systems. It provides practical guidance on how to inspect, assess, and clean ductwork to maintain indoor air quality and reduce risks such as fire hazards. At Clean Air 24 Seven, we align every project with TR19 Air specifications, from kitchen extract systems to full HVAC networks, so you can be confident that your building remains compliant with the highest health and safety standards.
