Cleaner air handling units mean cleaner air and better-performing buildings

Air handling units (AHUs) and ductwork move air through your whole building. Over time, dust, debris and contamination build up inside coils, filters, fans and ducts, which can reduce airflow, affect air quality and make systems work harder than they should.

Extract Assure provides professional commercial AHU and duct cleaning across the UK. We inspect, clean and test your system, then give you a clear written report. Pair it with air vent cleaning and TR19 compliance for complete ventilation hygiene. Call us or request an online quote.

Know the signs

When do air handling units and ducts need cleaning?

AHU and duct problems build slowly and out of sight, so they are easy to miss. These are the most common warning signs that your system needs professional attention.

  • Visible dust or debris at vents and grilles
  • Reduced or uneven airflow
  • Stale, musty or unpleasant odours
  • Dirty filters that clog quickly
  • A noisy or struggling fan
  • Complaints about air quality
The benefits

What does professional AHU and duct cleaning do for your building?

A clean ventilation system protects the people inside your building and the equipment that serves it.

  • Better air quality

    Removing dust and debris helps keep the air in your building fresher.

  • Improved airflow

    Clean coils, filters and ducts let air move the way your system was designed.

  • More efficient systems

    Clean equipment does not have to work as hard, which can help reduce wear.

  • Longer equipment life

    Fans, coils and components last longer when they are not clogged with dirt.

  • A healthier workplace

    Fewer odours and less dust make a more pleasant space for staff, guests and residents.

  • Documented evidence

    Reports, photographs and test results show what was done and the condition of your system.

Our process

Our AHU and duct inspection, cleaning and testing process, step by step

A clear, structured process from your first call to a written report you can act on.

  1. Call and agree the scope

    We discuss your building, the number of air handling units and duct runs, access and operating hours, then agree the scope and timing that suit your premises.

  2. Survey and inspect

    We locate each air handling unit and duct run and inspect them through access points to assess dust, debris and contamination.

  3. Record the pre-clean condition

    We photograph and record the condition of the system before any cleaning starts, so the results can be compared.

  4. Isolate and protect

    We safely isolate the unit or section being cleaned and protect surrounding areas from dust.

  5. Clean the air handling unit

    We clean accessible components such as coils, filters, fans, casings and drip trays.

  6. Clean the ductwork

    We remove dust and debris from the inside of the ductwork using suitable agitation and extraction.

  7. Test and verify

    We carry out post-clean checks, including visual inspection and, where appropriate, cleanliness testing in line with TR19 guidance, and make sure access panels are closed and sealed.

  8. Report and advise

    You receive a written report with before and after photographs, test and inspection results, notes on anything we could not reach and advice on how often to clean.

FAQ

Commercial AHU and duct cleaning questions, answered

Straight answers on AHU cleaning, duct cleaning and ventilation hygiene.

What is commercial AHU cleaning?

Commercial AHU cleaning is the professional inspection, cleaning and testing of air handling units in commercial buildings. It removes dust, debris and contamination from parts such as coils, filters, fans and casings so the unit delivers cleaner air and works efficiently.

What does AHU and duct cleaning include?

It covers inspection, cleaning of accessible AHU components, cleaning of ductwork, post-clean checks and a written report. We agree the exact scope with you after your first call.

Why do air handling units and ducts need cleaning?

Dust, debris and contamination build up over time and can reduce airflow, affect air quality and make equipment work harder. Regular cleaning keeps the system performing well.

How often should air handling units and ducts be cleaned?

It depends on the building, how it is used, the type of system and your risk assessment. Inspection results and TR19 guidance help set a suitable schedule, and we will advise on it.

What inspection and testing do you carry out?

We inspect the system before cleaning, record its condition, then carry out post-clean checks, including visual inspection and, where appropriate, cleanliness testing in line with TR19 guidance. See our step-by-step process above.

What report do I receive?

You receive before and after photographs, test and inspection results, notes on anything we could not reach and advice on how often to clean.

Is AHU cleaning the same as air vent cleaning?

They are related but different. AHU and duct cleaning deals with air handling units and ductwork, while air vent cleaning covers vents and grilles. Many buildings need both.

Will cleaning disrupt my building?

We agree the timing and scope with you in advance and plan the work around your operating hours to keep disruption as low as possible.
