What to include in a commercial HVAC installation brief
Start with the business address, building use, rooms to condition, approximate occupancy and hours of use. Plans, ceiling space, power arrangements and existing ventilation help an installer decide what to inspect. Ask for a site survey and a written proposal; a unit size suggested from floor area alone is not a completed design.
Commercial work may involve an office cassette, ducted zones, packaged plant or a larger variable-refrigerant system. The choice depends on the building and project requirements. Ask whether the business designs and installs that system type or only services smaller split units.
Compare the installation and handover scope
Have each bidder state who provides design, equipment, controls, electrical work, drainage, access equipment, commissioning and handover documents. Clarify out-of-hours work, builder coordination, removal of old units, maintenance requirements, GST and exclusions. Give every business the same drawings and timing so the quotes can be compared.

Select suitable businesses, review the named recipients and send one enquiry with your optional site, stage and system answers.
Check the contractor’s scope and credentials
ARC explains that people handling regulated refrigerant or components with a risk of release need the appropriate refrigerant-handling licence. Installation can also involve state-regulated electrical or mechanical work. Ask who performs each part and check the business authorisations and licences for the specific scope.
A building manager, landlord or builder may need to approve plant locations, access and shutdowns. Confirm these requirements before accepting a programme. For a large or unusual site, ask whether the installer provides engineering, commissioning records and ongoing service support.
Good questions. Plain answers.
Can a residential split-system installer do a commercial fit-out?
Some can, but a category listing does not establish commercial design or project capacity. Ask about similar premises, equipment types and who undertakes commissioning.
What should I send for a commercial air-conditioning quote?
Send the address, plans if available, building use, occupied hours, current equipment and target dates. The installer can tell you what further survey is needed.
How do I check refrigerant credentials?
Use ARC’s authorisation and licence lookup, and confirm state trade licences appropriate to the installation.
