AHU & Heat Recovery System Cleaning

Clean Air Starts at the Core of Your Ventilation System

At Canopy Cleaning Services, we provide expert Air Handling Unit (AHU) and Heat Recovery System (HRS)cleaning services across the UK. As the heart of your building’s HVAC system, your AHU and heat recovery units are critical to maintaining safe, efficient airflow and indoor air quality (IAQ). Over time, dust, biological contaminants, and debris build up within these systems, impacting health, system performance, and compliance.

Let us help you protect your building, staff, and compliance status with our certified AHU and HRS cleaning services.

Why AHU & Heat Recovery System Cleaning Is Essential

AHUs and heat recovery systems are responsible for filtering, regulating, and recirculating air throughout your building. However, without regular cleaning and servicing, they can quickly become breeding grounds for bacteria, mould, and other contaminants, which can:

Compromised indoor air quality increases health risks (especially in clinical, educational, or office environments)
Reduce system efficiency, increasing energy costs and equipment wear
Cause foul odours and poor airflow
Lead to legal non-compliance with UK workplace health and safety standards
