Document interfaces with adjacent systems. An AHU, its controls and the plant serving its coils need coordinated planning, but the equipment label does not automatically include every connected component in the contract.
Connect the asset list and proposed visit schedule to HVAC maintenance and servicing.
Define what each visit delivers
Define each task and its completion record. Attendance frequency alone does not show whether filters, drainage, fans or controls are inspected, cleaned, adjusted or otherwise maintained.
Set timing using manufacturer information, duty, applicable requirements and history. HSE's maintenance guidance explains planned work and competence. Record the programme’s basis and revisit affected tasks after significant changes or recurring defects.
Keep specialist checks identifiable
Separate routine service, refrigerant leak checks, energy inspections and specialist extraction examinations. Identify inclusions and separately commissioned work. Combined attendance still requires an appropriate scope, competence and evidence for each activity.
For F-gas equipment, document refrigerant data and responsibilities. Base the contract’s inspection entries on the actual installation rather than repeating the same requirement against every unit.
Agree access and response arrangements
Agree access to plant, working times, escorts, shutdowns and services that must remain available. Occupied areas beneath ceiling units require different arrangements from accessible plant-room equipment.
Define reporting, prioritisation, attendance scope and additional-work approval. A response target does not state repair duration: diagnosis, parts and access can leave further work after the initial visit.
Make costs and exclusions clear
Check coverage for consumables, parts, reactive attendance, cleaning and specialist inspections. Establish the process for extra-work findings. A fixed service fee only includes later replacement where the agreement expressly says so.
Review completed tasks alongside repeat faults, open recommendations and additional expenditure. Use that evidence to assess whether the programme still matches the assets and current building operation.
FAQs
Does an HVAC contract cover refrigeration too?
Only if refrigeration is expressly included. State its equipment, tasks, operating demands and responsibilities rather than relying on the HVAC heading.
Are all repairs included in the annual fee?
The written agreement controls inclusion. Compare labour and parts allowances, call-outs and the approval route for additional work before assessing the annual fee.
What should we send for a quotation?
Issue an asset list, historic reports, known defects, operating hours and access requirements. Flag information gaps and define what an initial survey must establish.
