HVAC Cleaning

HVAC cleaning is the professional removal of dust, debris, and microbial growth from your building’s Heating, Ventilation and Air Conditioning system. It includes cleaning ductwork, air handling units (AHUs), coils, fans, and filters to improve airflow, energy efficiency, and indoor air quality.

Regular HVAC cleaning prevents the build-up of contaminants that can affect air quality, energy performance, and equipment lifespan. In sensitive environments such as laboratories, healthcare settings and universities, it helps reduce the risk of airborne contamination and ensures compliance with ventilation hygiene standards.

The frequency depends on your environment and system usage.

1. Healthcare and laboratory facilities may require annual cleaning or verification.
2. Universities and commercial buildings typically benefit from inspection and cleaning every 12–24 months. A professional hygiene inspection can determine the ideal cleaning schedule for your site.

Common indicators include:

1. Reduced airflow or inconsistent temperatures.
2. Dust deposits near vents or diffusers.
3. Musty or unpleasant odours when systems run.
4. Increased energy consumption.
5. Poor indoor air quality or allergy-like symptoms among occupants. If any of these issues are present, a ventilation hygiene inspection is recommended.

At Clean Air 24 Seven, we clean and sanitise all key components, including:

1. Ductwork and plenums
2. Air handling units (AHUs)
3. Fans and fan coil units
4. Heat exchangers and coils
5. Filters and dampers
6. Grilles and diffusers This ensures the entire system performs safely and efficiently.

No. We plan all cleaning works around your operational schedule to minimise disruption. For hospitals, laboratories, and universities, we can perform cleaning during evenings, weekends or planned shutdown periods. Our teams use safe access methods and adhere to strict health and safety protocols.

We follow the NAAD21 recognised ventilation hygiene standards, which outline best practice for inspection, cleaning, and post-clean verification of HVAC systems. This ensures all work is fully documented, auditable, and compliant with UK regulations.

Professional HVAC cleaning delivers measurable benefits:

1. Improved indoor air quality.
2. Lower energy costs through efficient airflow.
3. Extended lifespan of air handling equipment.
4. Reduced risk of system contamination.
5. Compliance with HSE and building hygiene standards.
6. Healthier and more comfortable environments for occupants.

Yes. After every project, Clean Air 24 Seven provides a detailed hygiene report including:

1. Before and after photographs.
2. Findings and contamination levels.
3. Cleaning verification data.
4. Certification of cleanliness. This documentation is essential for compliance, audit records, and maintenance planning.

Absolutely. We can carry out visual inspections, particulate sampling, and microbiological testing to assess contamination levels before and after cleaning. These objective measurements confirm the hygiene condition of your ventilation system.

We combine technical precision, industry expertise, and a safety-first approach. Our team specialises in cleaning complex and sensitive HVAC systems across healthcare, education, laboratory and industrial settings. We provide full transparency, compliance documentation, and national coverage with minimal disruption to your operations.

While not all systems require statutory cleaning, UK health and safety regulations (such as the Workplace (Health, Safety and Welfare) Regulations 1992) state that ventilation systems must be “cleaned and maintained to prevent risks to health.” Regular HVAC hygiene inspections and cleaning demonstrate due diligence and help meet compliance obligations.

We use a combination of:

1. Mechanical brushing and vacuum extraction to remove dust and debris.
2. Compressed air agitation for hard-to-reach ductwork.
3. Disinfection and sanitisation treatments where microbial contamination is present. All equipment and cleaning agents are approved for use in sensitive and sterile environments.

Yes. We often partner with facilities management providers, building services engineers, and maintenance teams to deliver scheduled HVAC hygiene programmes. We also provide reports that integrate seamlessly into your internal maintenance documentation.

To receive a detailed quotation, we typically conduct a free or low-cost site survey to assess your system layout, contamination levels, and access requirements. You’ll then receive a full proposal outlining the scope of work, costs, and cleaning schedule.

Clean Air 24 Seven provides HVAC cleaning services nationwide across the UK. Our fully equipped mobile teams deliver high-quality ventilation hygiene services to clients in England, Scotland, and Wales.

Dust and debris restrict airflow and cause fans and motors to work harder, increasing energy use. Regular cleaning reduces system strain, improves heat exchange efficiency, and can lower energy costs by up to 20%.

Yes — especially in healthcare and laboratory environments. Contaminated air handling systems can harbour bacteria, mould, and viruses. Our antimicrobial cleaning and disinfection services help eliminate these risks and support infection control protocols.
