Improved indoor air quality
Removing dust, dirt and microbial contamination helps deliver cleaner air throughout the building, creating a healthier environment for occupants.
AHU Maintenance
Specialist AHU maintenance, including filter and bag replacement, internal cleaning, inspections and minor remedial works to improve air quality, maintain efficiency and ensure reliable system performance.
Overview
About the service.
Air handling units (AHUs) require regular maintenance to ensure efficient operation, reliable performance and good indoor air quality. Over time, filters become blocked, internal components accumulate contamination and general wear can affect airflow, system efficiency and overall performance.
At VMES, we provide specialist AHU maintenance services, including filter and bag replacement, internal cleaning, component inspections and minor remedial works. Our engineers help maintain system performance, identify potential issues and extend equipment lifespan, with all works supported by detailed reporting and photographic evidence.
What we do
- AHU inspections and maintenance
- Filter and bag replacement
- Internal component cleaning
- Minor repairs and remedial works
- Photographic reporting
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.
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.
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.
