What Is Ductwork Cleaning and Why Does Your Building Need It?
Ductwork is the network of channels that carries air, gases, or vapours through a building. Typically made from sheet metal, fibreglass, or flexible plastic, this system includes more than just the ducts themselves. It also covers fittings, grilles, extract ducts, insulation, and support brackets that keep the system in place.
In heating, ventilation and air conditioning (HVAC) systems, the term air ducts usually refers to the passages that move warm or cool air through homes and offices. Ductwork, however, is a broader term more often used in commercial and industrial settings. While air duct cleaning is common in domestic environments, ductwork cleaning is the professional service designed for large-scale HVAC systems in workplaces, factories, and public buildings.
Over time, dust, mould spores, allergens, and other debris build up inside ductwork. This build-up can lower air quality, reduce system efficiency, and even increase fire risks. Professional ductwork cleaning removes these contaminants, helping to create a healthier indoor environment, cut down on energy costs, and ensure compliance with health and safety regulations. For businesses, regular cleaning is not just good practice—it’s essential for safety, efficiency, and compliance.

Ductwork, Ventilation, Extraction and HVAC Explained
Ductwork cleaning is a comprehensive service that involves thoroughly cleaning the entire ventilation system within a building. This includes everything from air ducts and extract ducts to grilles, filters, and HVAC components. While air duct cleaning usually focuses on the passages that circulate air, mainly in homes and offices, ductwork cleaning is a broader, more technical term often applied to commercial and industrial systems.
It covers a wide range of specialist services such as ductwork cleaning, ESP (Electrostatic Precipitator) cell cleaning and maintenance, microbiological and PVT testing, laundry extract ventilation cleaning, and the upkeep of building-wide ventilation systems.
Together, these services ensure cleaner air, improved system performance, and regulatory compliance for any type of property.
Ductwork Cleaning – Frequently Asked Questions

What is an ESP and why is it important for AC systems?
An ESP (Electrostatic Precipitator) is a vital component in many air conditioning systems. It removes fine particulate matter, smoke, and airborne contaminants from the air, helping to maintain cleaner, healthier indoor environments—especially in commercial or industrial settings.
How often should I clean the ESP cells in my AC system?
Cleaning frequency depends on usage and environment, but ESP cells should generally be inspected and cleaned every 3 to 6 months. High-pollution or high-use areas may require more frequent attention.
What are the signs that my ESP cells need cleaning?
Common signs include reduced airflow, poor air quality, increased energy consumption, and overall decline in system efficiency. If your AC is underperforming, dirty ESP cells may be the cause.
Can I clean ESP cells myself, or should I hire a professional?
While light dusting or rinsing may be possible, ESP cell cleaning is best handled by professionals to ensure safety and proper handling of delicate components. Incorrect cleaning can damage the cells or reduce their effectiveness.
What’s the process for cleaning ESP cells professionally?
Professionals start by safely shutting down the AC system. They then remove the ESP cells, clean them using specialised equipment and approved cleaning agents, and carefully reinstall and test the system to ensure optimal performance.
What are the benefits of regular ESP cell maintenance?
Routine maintenance improves system performance, extends the life of your AC, reduces energy usage, and maintains better indoor air quality—delivering both health and financial benefits.
Is it possible to extend the lifespan of ESP cells through maintenance?
Yes. Regular inspection and professional cleaning can significantly extend ESP cell lifespan, saving on replacement costs and helping your AC run more efficiently over time.
What happens if I neglect ESP cell maintenance?
Neglecting ESP cell maintenance can lead to clogged or ineffective filtration, resulting in poor air quality, higher energy costs, and premature system wear or failure.

What is microbiological testing, and why is it important for HVAC systems?
Microbiological testing involves assessing HVAC systems for the presence of microorganisms such as bacteria, mould, and fungi. These contaminants can compromise indoor air quality and pose health risks to building occupants, making regular testing vital for safety and compliance.
How often should I consider microbiological testing for my HVAC system?
Testing frequency depends on the environment, system usage, and regulatory requirements. However, annual or bi-annual microbiological testing is recommended as a standard preventive measure.
What are the benefits of microbiological testing for HVAC systems?
Regular testing helps identify harmful microbial growth early, improving indoor air quality and supporting occupant health. It also prevents system damage caused by biological buildup, extending the lifespan of HVAC components.
How is microbiological testing performed by ACSEU Ltd?
ACSEU Ltd uses advanced sampling techniques to collect air and surface samples from your HVAC system. These samples are analysed in accredited laboratories, and we provide a detailed report with results, interpretations, and recommended actions if needed.
Can I detect microbiological contamination without testing?
While signs such as musty odours or visible mould may suggest contamination, microbiological testing is the only reliable way to confirm the type and extent of microbial presence in your HVAC system.
What is PVT (Pressure-Volume-Temperature) testing, and why is it necessary for HVAC systems?
PVT testing measures the pressure, volume, and temperature parameters of an HVAC system. It’s essential for ensuring that systems operate efficiently, maintain proper airflow, and comply with performance and safety standards.
How frequently should I consider PVT testing for my HVAC system?
PVT testing is typically recommended during system installation, after major modifications, or as part of routine maintenance. The frequency depends on system usage, complexity, and compliance obligations.
What benefits does PVT testing offer for HVAC systems?
PVT testing optimises system performance, boosts energy efficiency, and helps detect potential issues early. This can reduce operational costs, improve comfort, and ensure regulatory compliance.
Can HVAC systems operate efficiently without PVT testing?
Without PVT testing, HVAC systems may not perform at optimal levels. This can lead to inefficiencies, inconsistent temperatures, and increased energy usage. PVT testing is a proactive way to maintain system health and efficiency.
Are there compliance regulations associated with microbiological and PVT testing for HVAC systems?
Yes. ACSEU Ltd ensures all microbiological and PVT testing complies with relevant health, safety, and industry standards. We help clients meet legal obligations and maintain a safe, compliant HVAC environment.
