Air systems

AHU (Air Handling Units)

Protect airflow and indoor comfort with coordinated checks of filters, coils, fans, dampers, drainage and controls.

The equipment

How the system does its job.

An air handling unit conditions and moves air through a building using filters, cooling coils, fans, dampers and controls. Restricted airflow, dirty heat-transfer surfaces or mechanical and control faults can reduce comfort and place extra demand on the wider cooling system.

Diagnosis before decisions

Read the warning signs. Test the cause.

Common faults and warning signs

  • Weak or uneven supply airflow
  • High humidity or poor temperature control
  • Belt noise, fan vibration or motor trips
  • Water carryover, drain blockage or musty odours

What we inspect or repair

  • Filters, coils and casing cleanliness
  • Fans, motors, belts, bearings and vibration
  • Dampers, actuators and control signals
  • Condensate tray, drain and trap
  • Supply/return temperatures and accessible airflow points

A clear service process

From symptom to stable operation.

Measurements guide the repair scope. After the agreed work, operation is checked again against the original symptom.

  1. 01

    Review

    Confirm the affected zones, schedule and control demand.

  2. 02

    Inspect

    Check airflow path, cooling coil, fan assembly and drainage.

  3. 03

    Correct

    Complete the agreed cleaning, adjustment or repair.

  4. 04

    Balance

    Verify fan operation, temperature change and control response.

Where it fits

Built around the real application.

  • Offices and retail
  • Hotels and hospitality
  • Healthcare and education
  • Commercial and industrial facilities

Preventive maintenance guidance

  • Set filter inspection intervals to the site environment.
  • Clean coils and drain trays before airflow or hygiene deteriorates.
  • Track belt condition, vibration and temperature difference across the coil.
