A maintenance call turns into a suspected refrigerant leak. The tradie at the door is not cleared for refrigerant work. Before you start air conditioning business planning, decide which jobs you will sell, who may do them and when the crew must stop.
Use the shared-English HVAC business start-up walkthrough for the broad business sequence. The Australian work starts with local licence boundaries, refrigerant authority, electrical coordination, GST records, written variations and a dispatch gate that controls every booking.
Start air conditioning business planning with work you can support
Pick the customer, equipment and service area before buying tools. Your opening service menu controls the licences, instruments, vehicle stock, suppliers and subcontractors you need.
Choose residential, commercial or a narrow mix
Residential work can include owner-occupied homes, rentals and strata properties. Commercial work can involve site contacts, inductions, access windows, asset registers, purchase orders and longer payment processes.
Do not promise both markets just because you have worked on both. Write down:
- The suburbs and postcodes you can cover without losing the day to travel.
- The equipment types and brands you can inspect and support.
- The hours when you will answer and attend calls.
- The person who can approve work at each site.
- The response time you can meet with your available crew.
- The work you will refer or decline.
Test the plan with real enquiries. Ask prospective customers what equipment they have, what goes wrong and how they approve repairs. Ask suppliers what they can stock and how warranty returns work. Compare that demand with your own capacity and cash.
Air conditioning can be a good business when the work fits your authority, skill, service area and payment cycle. A broad claim that the market is growing tells you nothing about whether your first ute can complete a local job profitably.
Define cooling and heating boundaries
Heating business setup needs its own task check. Reverse-cycle air conditioning may sit inside your planned scope. Gas heating, hydronic systems, mains electrical work and specialist controls may not.
Name the task, not the broad service. Diagnose a controller. Open a refrigerant circuit. Replace a drain. Connect equipment. Commission a system. Each verb exposes the licence, tool and record needed for the job.
Choose the service scope before buying equipment
Build three lists: do, coordinate and decline. Keep the first list narrow enough to dispatch without guessing.
| Proposed task | Do with your crew | Coordinate | Decline for now |
|---|---|---|---|
| Inspect and diagnose | Name the equipment, tests and permitted boundaries | Record when an electrician or controls specialist takes over | List unsupported systems and inaccessible sites |
| Perform planned maintenance | Define cleaning, readings, drainage checks and records | Record any specialist access or electrical work | Exclude repairs that fall outside the visit scope |
| Open a refrigerant circuit | Name the authorised worker, instruments and recovery path | Record specialist or licensed support | Stop if the authority or equipment check fails |
| Install or replace a system | Define placement, pipework, drainage, testing and commissioning | Record electrical, roofing, structural and lifting work | Exclude equipment and access conditions you cannot support |
A maintenance booking can become a refrigerant repair. An installation can reach site before anyone notices that the electrical work falls outside the crew's authorised scope. Put those stop points on the list now.
A sound way to start air conditioning business operations is to accept one controlled group of tasks, close those jobs properly and expand only after the records support it.
Clear Australian authority checks task by task
Business registration does not give you permission to perform regulated trade work. A trade licence does not automatically cover every refrigerant, electrical, plumbing, roofing or structural task on an installation.
Record each answer against a task. Keep the body, official page, answer and date in one authority matrix.
Register the business and tax records
Ask ASIC (opens in a new tab) how company registration or business name registration applies to your chosen structure. Keep the accepted registration details with the business records.
Ask the Australian Taxation Office (opens in a new tab) about the ABN, GST, BAS and tax-invoice questions that apply to the business. Do not copy the GST treatment from another tradie's invoice.
Registration comes first as an entity question. Permission to advertise, contract for and perform each task is a separate check.
Check HVAC business licensing in your jurisdiction
Ask your state or territory licensing regulator which licence class covers each task you plan to sell. Write down the answer beside diagnosis, repair, installation, commissioning, drainage and contracting.
For example, a NSW business would ask NSW Fair Trading (opens in a new tab) about trade and contractor licence questions within that body's scope. A business elsewhere must use its own state or territory regulator. Do not assume an answer from one jurisdiction applies in another.
Ask the same regulator what must appear on advertising, quotes, contracts, vehicles and completion records. Ask before copying a residential installation contract from another business.
Electrical coordination needs a separate row. If the proposed connection, circuit or switchboard work sits outside your crew's authority, assign it to the correctly licensed electrical contractor. Do not bury that work inside an installation description.
Check refrigerant handling requirements
Ask the Australian Government Department of Climate Change, Energy, the Environment and Water (opens in a new tab) which national refrigerant licensing and authorisation framework applies to the tasks, workers and business you plan to use.
Mark every task that can open a refrigerant circuit, add or remove refrigerant, recover material or create a refrigerant record. Record who may do it, what authority is required and what must come back with the job file.
Do not treat a card in the office as a complete compliance process. The dispatch decision must check the person, task, instruments, cylinders, recovery route and records together.
Check safety and worker cover separately
Ask your state or territory WHS regulator about workplace safety duties for the work you accept. A NSW business would use SafeWork NSW (opens in a new tab) for workplace safety questions. Build the job procedure around electrical exposure, roof access, ladders, lifting, heat, occupied rooms and hazardous substances.
Ask your state's workers' compensation insurer or regulator about cover for workers. In NSW, that regulatory question goes to the State Insurance Regulatory Authority (opens in a new tab). Keep worker cover separate from vehicle, tool, public liability and other insurance discussions.
Give an insurance adviser the actual scope. List refrigerant work, installation, subcontractors, vehicles, stored equipment and service areas. Ask for current written terms rather than assuming an old policy covers the new work.
Turn the authority matrix into a dispatch gate
The matrix is not filing. Use it before advertising, quoting and assigning work.
| Task | Licence or authority check | Assigned person | Vehicle and instruments | Coordinated trade | Records due back |
|---|---|---|---|---|---|
| [Describe the exact task] | [Official body and recorded answer] | [Named authorised person] | [Required tools, stock and safety gear] | [Trade and scope] | [Readings, photos, approvals and forms] |
Put one task on each row. Separate diagnosis from refrigerant work. Separate equipment placement from electrical connection. Separate drainage from roof penetration. Separate installation from commissioning.
Before dispatch, ask:
- Does the assigned tradie have authority for the booked task?
- Is the required instrument, cylinder, stock and safety gear on the ute?
- Has any coordinated trade accepted its part of the work?
- Does the job file show the customer, equipment, access and approval contact?
- What event makes the tradie stop and call the office?
A maintenance booking that reveals a suspected leak has crossed a boundary. If the assigned person is not cleared and equipped for refrigerant work, stop. Reassign the job or book a return visit.
Do the same when an installation reaches an electrical boundary. Customer pressure does not expand a licence or put the right instrument on the ute.
Calculate start-up cash from the service menu
There is no useful universal start-up figure. Build yours from current supplier quotes, professional advice, payment timing and the exact tasks you chose.
Separate the cash into these buckets:
| Cash bucket | Figures to collect |
|---|---|
| One-off setup | Registration, authority checks, advice, initial tools, instruments, vehicle fit-out and forms |
| Per-job costs | Equipment, parts, freight, consumables, subcontractors, access, disposal and payment costs |
| Ongoing overhead | Vehicle costs, premises, administration, communication, bookkeeping, insurance and tool replacement |
| Working capital | Owner labour, wages, materials and overhead due before the customer pays |
Owner labour is a job cost even when you do not create a separate payroll entry for yourself. Leaving it out makes the cash plan and job result look better than they are.
Ask suppliers for written equipment and consumable figures. Ask subcontractors for their scope and commercial terms. Ask advisers and insurers for current written quotes. The first-job start-up cost guide shows how to separate setup spending from working capital.
Set a cash gate before accepting an equipment order or slow-paying commercial job. Confirm that the business can buy the equipment, cover labour, pay coordinated trades and carry overhead until the customer's payment clears.
Match the ute and supply chain to each task
Build a vehicle list for each promised service. One generic tool list is not enough.
For diagnosis, list the test instruments, leads, equipment information, access gear and field forms. For refrigerant work, list the authorised person, recovery equipment, cylinders, leak-testing equipment, consumables and required records.
For drainage work, list access, clearing, repair, fall testing and clean-up items. For installation, list measuring, fixing, pipework, drainage, access and protection needs. For commissioning, list the readings, photos, equipment identifiers, customer handover and completion records.
Before dispatch, inspect damaged leads, batteries, stock, cylinders and instruments. Record calibration or accuracy checks where the task needs them. Replenish consumables after the job, not when the next customer is waiting.
Confirm supplier ordering cut-offs, pickup arrangements, returns and warranty paperwork. Confirm where removed equipment and recovered material go. Get a clear scope from electrical, roofing, plumbing, lifting or structural subcontractors before promising a completion date.
Price labour, materials and overhead before markup
Inspect before pricing. The indoor or outdoor unit may not fit where the enquiry assumed. That can change pipework, drainage, access, electrical coordination and labour.
Build direct labour from travel, supplier collection, site work, testing, paperwork and close-out. Add equipment, accessories, freight, consumables, subcontractors, hired access, disposal and an allocated share of overhead.
An HVAC equipment estimate should name the proposed equipment and the accessories included. It should also state the site facts that remain open. Do not use a supplier equipment price as the job price.
Markup is added to cost to form a selling price. Margin is profit measured as a share of the selling price. Mixing them makes a quote look healthier than the completed job.
The Oak Street electrical job is the house example, not an air conditioning rate. Quote Q-1847 was 1,105. Job cost was 850, so profit against the original quote was 255. Margin was 255 ÷ 1,105, or about 23%. Markup was 255 ÷ 850, or 30%. All figures are sample currency units.
The costs of the later variation are not given. Do not use the final invoice to recalculate profit. Use the profit margin calculator with your own completed-job costs when checking future quotes.
Write the quote so the crew knows where to stop
A quote needs a controlled scope before it needs polished formatting. State:
- The equipment and accessories included.
- The indoor and outdoor unit locations.
- The assumed pipework, drainage and cable routes.
- Access, lifting and property-protection arrangements.
- Electrical and other coordinated trade work.
- Testing, commissioning and handover records.
- Disposal and clean-up.
- Exclusions for concealed conditions and unapproved extra work.
Use a range estimate while major facts remain open. Issue a fixed quote only after the equipment, access, placement and trade boundaries are controlled. The air conditioning replacement quote guide gives you the next job-level scope check.
On the Oak Street bathroom, estimate E-1847 gave a range of 900–1,400 before the fixed scope. Quote Q-1847 was 1,105. The ceiling was lined and chasing was excluded.
Extra cable and chasing were approved on site as a 160 variation. Invoice INV-1847 became 1,265. The variation costs are unknown, so the original job cost of 850 cannot be combined with the invoice total to claim a new profit figure.
Use the same control on an air conditioning job. If unit placement, pipework, drainage or access changes, stop. Describe the extra work and price. Get written approval for the variation. Then proceed.
Run one job path from enquiry to payment
At enquiry, record the customer, site, equipment identifiers, symptoms, access, previous work and person authorised to approve the job. Ask for photos when they can expose placement or access problems, but do not use them as a substitute for an inspection where measurements or testing decide the scope.
Before booking, run the dispatch gate. Assign the authorised person, required instruments, parts and coordinated trades. Put the accepted quote and exclusions in the job file.
On site, record readings, photos, equipment details, work completed, customer approvals and anything left outstanding. At handover, give the customer the documents required for that job and send the invoice against the accepted scope and approved variations.
For planned servicing, define the maintenance visit scope before setting recurring service billing. Record what the tradie inspected, cleaned, tested and found at every visit. Use the air conditioning maintenance plan process to keep recurring work tied to equipment and completed tasks.
Follow up unpaid invoices against the agreed payment terms. Do not let a missing purchase order, site contact or completion record become an excuse discovered after the work.
Review each completed job before adding services
Compare actual vs estimated cost by labour, equipment, materials, subcontractors and overhead. Check which site facts were missed and which dispatch assumptions failed.
Measure job profitability against the original accepted scope. Keep approved variations separate unless their own costs have been recorded. An invoice total alone does not tell you whether the job made money.
Fix one operating gap before widening the service menu. Change the enquiry question, site inspection, quote exclusion, vehicle list, dispatch rule or close-out record that allowed the miss.
Once the paper process is clear, job management software for tradies can keep the enquiry, dispatch check, quote, variation, job record and invoice on the same job. Yes Foreman connects those job records from the office to the field; it does not replace the authority decision or site inspection.
Common questions
Should I use a fixed-dollar rule to decide between repair and replacement?
No. Inspect the equipment, diagnose the fault and record the system condition, support, access and customer needs. Quote the defined repair or replacement scope from those facts, not a slogan.
Should equipment age decide the replacement quote?
Age is one input, not the scope. Check the manufacturer's information, measured condition, fault, parts support, site constraints and the customer's required outcome. Ask what the customer means if they refer to an unnamed age rule.
Write the first-job control sheet
If you are ready to start air conditioning business operations, write one page for the first service you will accept. Name the service area, tasks your crew will do, tasks you will coordinate and work you will decline.
Add the authority matrix, dispatch gate, cash gate, quote exclusions and records due back from site. Then test that sheet against the next real enquiry before you advertise or book the job.
