Heating Ventilation & Air Conditioning Decontamination

Major & Complex Claims
Service icon

The Damage Control industry has long required a reliable solution for thoroughly decontaminating Heating, Ventilation, and Air Conditioning (HVAC) systems and associated ductwork following a fire. Traditional cleaning methods, while useful for removing loose deposits, fail to achieve the level of decontamination and neutralisation necessary for internal surfaces. The challenge lies in providing a comprehensive solution that achieves the same level of cleanliness internally as on external surfaces with comparable contamination.

Polygon's Industry-Leading Decontamination Method

Polygon has developed a specialised approach to HVAC decontamination, ensuring full access and thorough treatment of all system components. From the air intake at the Air Handling Unit (AHU) to the exhaust system, every part of the system is meticulously cleaned and decontaminated. This method guarantees that internal contamination levels are reduced to match those of external surfaces.

By employing this industry-leading process, Polygon offers peace of mind to the insurance industry, demonstrating that replacing ductwork is no longer the only option after contamination.

The Importance of Clean Air for Healthy Buildings and Employees

In most modern buildings, HVAC systems play a critical role in delivering and extracting the air we breathe. Ensuring that this air is clean and free from contaminants is essential for the health and well-being of employees and building occupants.

Regular maintenance and decontamination of HVAC systems should be a priority for all property owners and employers, regardless of fire-related incidents. Clean air not only supports healthy living but also fulfils an organisation’s duty of care.

Standard duct cleaning services often overlook the importance of eliminating contamination within extract systems. Modern AHUs recycle airborne particles back into the building, including bacteria, mould spores, and odours that standard filters cannot remove. These contaminants are then delivered back into the building, compromising air quality.

Commercial HVAC Decontamination and Cleaning Services

Polygon UK provides a bespoke HVAC decontamination service, particularly effective after soot and smoke contamination caused by fires.

The Impact of Smoke Contamination on HVAC Systems

Smoke from a fire, or even an adjacent property, can infiltrate HVAC systems and deposit soot and chloride-laden residues. These residues are highly corrosive and can cause long-term damage if not professionally treated. Furthermore, contaminated ductwork can spread pollutants to areas of the building that were not directly affected by the fire.

To address these challenges, Polygon's Project Managers perform contamination profiling during the initial assessment. This helps identify the spread of smoke contamination throughout the property and ensures effective decontamination.

Advantages of Polygon’s Methodology

Polygon’s methodology, refined over years of experience across various sectors, significantly reduces the need for additional access hatches. This minimises business interruptions, allowing decontamination work to be carried out during normal operating hours, ultimately reducing project costs.

Polygon provides skilled and experienced teams capable of delivering effective HVAC decontamination services for both the insurance industry and the private sector.
