Servicing scope

What Can Be Included in an AHU Service?

The checklist is agreed for your unit and accessible components. Tell us about any known faults before booking so they can be considered separately from routine servicing.

01

Maintenance History

Review the last service date, previous findings and outstanding actions to identify gaps in the planned preventive maintenance (PPM) schedule.

02

Unit Condition

Check accessible areas of the AHU for visible condition changes and record observations relevant to ongoing maintenance.

03

Filter Condition

Review accessible filter condition as part of the agreed service. Confirm any required replacement, specification and supply separately.

04

Belts and Service Items

Check the condition of accessible belts and service items where fitted. Repairs and replacement parts depend on the findings and agreed scope.

05

Operating Observations

Review reported changes in operation alongside service observations. A recurring shutdown or active fault may need a separate diagnostic visit.

06

Access and Service Records

Record areas checked, access limitations and recommended follow-up, helping the facilities team keep a usable maintenance history.

Planning your visit

How an AHU Maintenance Visit Works

A useful service starts with the right asset information and a practical access plan. Fixin4u confirms suitability and the proposed scope before the visit is arranged.

Share the Unit Details

Send the site postcode, number of units, make and model where known, and any service records or reported concerns.

Agree Access and Scope

Explain where the unit is located, site induction requirements and available shutdown windows so the visit can be planned.

Carry Out the Agreed Checks

The accessible unit and relevant service items are checked within the confirmed scope. Findings may identify work needing separate approval.

Record the Next Steps

Use the service findings to prioritise follow-up and review the maintenance schedule. Any additional repair or component work is agreed separately.

Choose the right visit

Planned AHU Maintenance or Reactive Repair?

Choose by the main reason for the visit: scheduled upkeep and condition records, or investigation of an operating fault. Servicing does not automatically include breakdown diagnosis or repairs.

Choose Planned Maintenance

A scheduled or overdue service suits a unit needing routine condition checks, a review of service items and a clearer maintenance record. Tell us about recurring concerns even if the AHU is currently running.

Choose Fault Finding

If the AHU will not start, repeatedly stops or has a persistent operating fault, request a diagnostic visit. Identifying the cause comes before deciding which repair or part is needed.

Already dealing with a fault? Use AHU Repairs and Fault Finding and include the symptoms and fault history. A future servicing schedule can be reviewed after the immediate issue is understood.

 Ageing unit concerns
