The Crucial Role of AHUs in London’s Landmark Buildings
Air Handling Units are far more than just boxes of metal; they are the lungs of a building. These complex systems are responsible for controlling and conditioning the air supplied to various spaces, playing a vital role in:
- Temperature Control: Maintaining precise temperature setpoints, crucial for occupant comfort and the optimal operation of sensitive equipment.
- Humidity Management: Regulating moisture levels to prevent discomfort, protect building materials, and inhibit mould growth.
- Air Filtration: Removing particulate matter, allergens, pollutants, and even microscopic contaminants from both fresh and recirculated air, safeguarding indoor air quality (IAQ).
- Ventilation: Introducing fresh outdoor air to dilute indoor pollutants and carbon dioxide, essential for cognitive function and overall health.
- Energy Efficiency: Optimising air distribution and conditioning processes to minimise energy consumption, a critical factor in the operational costs of large buildings.
In the dense urban environment of Central London and the City, where external air quality can fluctuate and internal occupancy is often high, the performance of AHUs is paramount. They are the silent guardians of occupant health, productivity, and the overall economic viability of these monumental investments.

Beyond Installation: Comprehensive AHU Servicing and Maintenance
The installation of an AHU is just the beginning of its lifecycle. To ensure sustained optimal performance, energy efficiency, and longevity, regular and professional servicing is indispensable. ACL offers a comprehensive suite of AHU servicing and maintenance solutions tailored for the unique demands of Central London and the City’s large buildings.
Routine Servicing: The Foundation of Reliability
Our proactive maintenance programs are designed to prevent unexpected breakdowns and maintain peak operational efficiency. Routine servicing typically includes:
- Filter Inspection and Replacement: This is arguably the most crucial aspect of AHU maintenance. We inspect existing filters for soiling and replace them with the correct grade of filters to ensure optimal air quality and prevent strain on the fan motors and coils. For large buildings in London, this can involve hundreds of filters and requires meticulous planning.
- Belt Inspection and Tensioning: Fan belts are vital for efficient air movement. We check for wear, tear, and proper tension, replacing belts as necessary to prevent slippage and ensure optimal airflow.
- Motor and Bearing Lubrication: Rotating components require regular lubrication to prevent wear and premature failure.
- Coil Cleaning and Inspection: Cleaning of heating and cooling coils improves heat transfer efficiency and prevents blockages. We also inspect for any signs of damage or corrosion.
- Drain Pan and Condensate Line Cleaning: Ensuring proper drainage prevents water build-up, which can lead to mould growth and water damage.
- Electrical Connection Checks: Verifying that all electrical connections are secure and free from corrosion.
- Functionality Tests: Running the unit through its operational cycles to ensure all components are working as intended.
Belt Changes: Keeping the Air Flowing Smoothly
Fan belts are a common wear item in AHUs. Over time, belts can stretch, crack, or become brittle, leading to reduced airflow, increased energy consumption, and potential motor damage. ACL’s servicing protocols include a thorough inspection of all fan belts. We are equipped to carry out prompt and efficient belt replacements, utilising high-quality, durable belts that meet the specific requirements of your AHU and application. Our technicians ensure that new belts are correctly tensioned, prolonging their lifespan and maintaining optimal fan performance.
Motor Replacements: When Power Fails
AHU fan motors are the driving force behind air circulation. While designed for durability, motors can eventually fail due to age, electrical issues, or lack of maintenance. A malfunctioning motor can bring comfort to a standstill. ACL’s experienced engineers can diagnose motor faults swiftly and carry out professional motor replacements. We source appropriate replacement motors that match the original specifications, ensuring compatibility and optimal performance. Our process includes:
- Accurate Diagnosis: Identifying the root cause of motor failure.
- Sourcing the Correct Motor: Obtaining a high-quality replacement motor from reputable manufacturers.
- Safe and Efficient Installation: Disconnecting the old motor, installing the new one, and ensuring all electrical and mechanical connections are secure.
- Testing and Commissioning: Thoroughly testing the new motor and the entire AHU to confirm it is operating correctly and efficiently.
