Improved indoor air quality
Removing dust, dirt and microbial contamination helps deliver cleaner air throughout the building, creating a healthier environment for occupants.
AHU Cleaning
Specialist cleaning of air handling units (AHUs), removing dust, dirt and microbial contamination to improve indoor air quality, maintain system efficiency and support reliable system performance.
Overview
About the service.
Over time, air handling units (AHUs) accumulate dust, dirt and other airborne contaminants on internal components such as filters, coils, fans and drain trays. Left unchecked, this build-up can reduce system efficiency, restrict airflow, impact indoor air quality and increase maintenance costs.
At VMES, we deliver professional AHU cleaning services to restore system cleanliness, improve operational performance and support healthier indoor environments. Our qualified engineers thoroughly clean internal AHU components with minimal disruption, supported by detailed inspections, before-and-after photography and comprehensive reporting.
What’s included
- Internal AHU cleaning
- Coil, filter & heat exchanger cleaning
- Fan, motor & internal component cleaning
- Condensate tray & drain cleaning
- Photographic reporting & certification
Our Approach
Restoring system performance.
Every AHU cleaning project begins with a detailed inspection of the unit to assess its condition, identify contamination levels and determine the most appropriate cleaning approach. Our qualified engineers safely isolate the unit where required before cleaning internal components including filters, coils, fan sections, drain trays and internal casings using specialist equipment and approved cleaning methods.
The result is a cleaner, more efficient air handling unit that supports improved airflow, better indoor air quality and reliable long-term system performance, all while keeping disruption to building occupants to a minimum.
Why it matters
Protecting your air handling unit.
Regular AHU cleaning helps maintain indoor air quality, improve system efficiency and protect critical ventilation equipment from unnecessary wear and contamination.
Increased system efficiency
Clean coils, fans and internal components improve AHU efficiency, increasing airflow and reducing energy consumption.
Equipment protection
Routine cleaning reduces contamination build-up that can contribute to premature wear, helping extend the lifespan of key AHU components.
Planned maintenance
Regular cleaning, with detailed reporting, helps identify issues early and provides a documented maintenance record.
Detailed Reporting
Complete visibility.
Every AHU cleaning project is fully documented, giving you a clear record of the work completed and the condition of your equipment. Before-and-after photographs capture the improvement in cleanliness, while our reports highlight any observations or recommendations identified during the cleaning process.
This provides facilities managers and building owners with a comprehensive record of maintenance, helping demonstrate good asset management, support planned maintenance programmes and identify any remedial works before they become more significant issues.
How it works
From survey to certificate.
A clear, accountable process — documented at every step.
01
Inspect
We inspect the air handling unit, assess contamination levels and identify the components requiring cleaning before work begins.
02
Prepare
The AHU is safely isolated where required, with access gained to internal sections to allow safe and effective cleaning.
03
Clean
Dust, dirt and contamination are removed from coils, filters, fan sections, drain trays and internal casings using specialist cleaning methods.
04
Report
You receive before-and-after photographic evidence, digital reporting and any recommendations, providing a clear record of the work completed.
Where we work
Sectors we serve.
We clean and certify ventilation systems across a wide range of commercial and industrial settings.
FAQs
Common questions.
How often should an AHU be cleaned?
Cleaning frequency depends on the building type, operating environment and maintenance schedule. Regular inspections help determine when cleaning is required.
Why does an air handling unit need cleaning?
Dust and airborne contaminants accumulate on internal components, reducing efficiency, affecting indoor air quality and increasing maintenance requirements.
Will AHU cleaning disrupt our building operations?
We plan our work to minimise disruption and can often carry out cleaning outside normal operating hours where required.
What do I receive after the cleaning is complete?
A detailed report with before-and-after photographs and recommendations where required.
