Choosing a Commercial Air Conditioning Contractor in Queensland

Ask for the contractor's legal entity and relevant QBCC licence details, then check current status and scope through the official information and registers. Queensland mechanical services air conditioning and refrigeration work has different licence classes and responsibilities. A licence should match the work and role, including any design responsibility being accepted.

Do not assume a company name, an advertisement or experience with domestic splits establishes capability for a larger commercial system. Ask how the proposed work fits the licence scope and whether specialist design or subcontracting is involved. Resolve unclear responsibility before accepting the quotation.

Personnel performing regulated refrigerant work need the appropriate refrigerant handling authorisation. Business authorisation for acquiring, storing or disposing of refrigerant is a separate consideration under the relevant scheme. An ARC licence is not a replacement for every other mechanical, electrical or building-work requirement.

Ask who will recover refrigerant, investigate leaks, charge equipment and complete the relevant records. Electrical work also needs the appropriate licensing arrangements. A single general statement that the team is 'fully licensed' is less useful than confirming the people and responsibilities for the actual scope.

The quote should identify who determines heat loads, equipment selection, ventilation interfaces and controls. Larger or more complex sites may need a specialist mechanical designer and input from other building professionals. Make sure the design brief includes intended occupancy, operating hours and the proposed fit-out.

Ask who coordinates landlord approval, roof access, structural supports, fire-related interfaces, electrical supply and penetrations where they apply. If these are excluded, identify the person who will arrange them. Gaps between contractors can create cost and programme problems even when each individual quotation seems clear.

National Construction Code — building requirements

Compare equipment models, zones, controls and installation assumptions rather than headline totals. A quote should state included work, exclusions, GST treatment, access assumptions and the variation process. Record how unexpected defects in existing infrastructure will be handled before work begins.

Confirm insurance arrangements appropriate to the work and ask for relevant project experience without treating an unverified testimonial as technical evidence. A contractor should be able to explain why the proposed system suits the brief and what limitations or alternatives were considered.

• Legal entity, licence class and current status.
• Design responsibility and specialist subcontractor scope.
• Equipment schedule and included building-service work.
• Access, approvals, exclusions and variation process.
• Insurance, commissioning, warranty and maintenance terms.

Ask which operating checks, balancing, control tests and commissioning records will be provided for the installation. Requirements vary with the equipment and project, so a generic 'tested and working' line may not explain enough. Handover should help the operator understand schedules, zones, alarms and safe routine care.

Obtain manuals, warranty information, model details and a record of any outstanding items. Agree who handles defects and how the site reports problems. Manufacturer warranty conditions and workmanship terms should be supplied in writing; do not assume all brands or contractors use the same conditions.

Check how servicing will be arranged and whether safe access has been designed into the installation. Ask about parts availability, fault reporting and the process for urgent attendance without assuming a guaranteed response time. Equipment critical to a process may need a separate contingency plan.

When enquiring with Hart Air, describe the building, existing system and proposed work. Confirm suitability and availability, particularly for VRF, cassettes, packaged plant or specialist ventilation interfaces. This procurement guide is not a claim that every commercial system or design discipline is included in Hart Air's service scope.
