Yes. In many cases, an air handling unit can be repaired, refurbished or overhauled rather than replaced.

Our engineers can assess the condition of the AHU and its mechanical and electrical components, identifying what has failed and what needs attention. Depending on the condition, this can include repairing or replacing motors, fans, bearings, drives, controls and other critical components.

Repairing an existing AHU can often be a more practical and cost-effective option than replacing the complete unit.

AHUs contain a number of mechanical and electrical components, so there can be several causes of failure.

Common problems include motor and bearing failure, fan imbalance, worn belts, vibration, electrical faults, drive failure, control issues and general mechanical wear.

The important thing is to understand what caused the failure. Replacing a failed component without addressing the underlying problem can simply result in the same fault occurring again.

An AHU will often show signs of deterioration before it fails completely.

Unusual noise, increased vibration, overheating, reduced airflow, inconsistent temperature control, electrical faults and increased energy consumption can all indicate that something isn't operating correctly.

Early investigation gives maintenance teams the opportunity to identify developing faults before they become an unplanned failure — and before the cost and disruption of the repair increases.

Many of the mechanical and electrical components within an AHU can be repaired, refurbished or replaced.

This can include electric motors, fans, bearings, shafts, pulleys, drives, control equipment and other rotating or electrical components.

Where suitable replacement components are no longer readily available, repair or component refurbishment can provide an alternative to replacing the complete AHU.

Replacing an entire AHU isn't always the best option.

The decision should consider the condition of the existing equipment, cost of repair, availability of replacement parts, expected remaining service life, energy efficiency and the consequences of taking the system out of service.

A properly assessed repair or refurbishment can extend the working life of an existing AHU and avoid the cost and disruption associated with a complete replacement.

Our approach is straightforward: assess the equipment first, then make the right engineering decision.

There isn't a standard price for AHU repairs because every unit and every failure is different.

The cost will depend on factors such as the size and design of the AHU, the failed components, extent of damage, availability of replacement parts and any machining or specialist repair work required.

A proper inspection allows the repair requirement to be understood before unnecessary components are replaced, giving you a clearer picture of the work and associated cost.

That depends on the type of failure, the size of the equipment and the components that need repairing or replacing.

For critical AHUs, minimising downtime is often just as important as the repair itself. Getting the equipment assessed quickly means the required work can be identified and planned without unnecessary delay.

Where replacement parts are obsolete or difficult to source, component repair, refurbishment or precision engineering can also provide an alternative to waiting for a new component.

An AHU overhaul starts with understanding the condition of the equipment.

The relevant mechanical and electrical components are inspected for wear, damage, vibration and deterioration. Depending on the findings, refurbishment may include motor or fan repairs, bearing replacement, shaft or component repair, drive and electrical repairs, reassembly and testing.

The objective isn't simply to get the AHU running again. It's to return the equipment to reliable service and address the cause of the original problem wherever possible.

Yes. Fans, motors and drive systems are critical to AHU operation and can often be repaired rather than replaced.

Motor bearing failure, winding faults, fan imbalance, shaft wear, drive faults and electrical problems can all affect AHU performance.

Repairing these individual components can provide a significantly more practical solution than replacing an entire air handling unit, particularly where the rest of the equipment remains in good condition.

The best time to find an AHU problem is before it becomes a breakdown.

Regular inspection, preventative maintenance and condition monitoring can identify developing problems with motors, fans, bearings and other rotating equipment.

Monitoring vibration and temperature, combined with routine inspections and planned maintenance, can help maintenance teams understand the condition of critical AHU equipment and plan intervention before a failure results in disruption.
