A tradie reaches a commercial roof and finds more units than the quote identifies. A clear air conditioning maintenance plan stops the guessing: name the assets, define each visit and draw a hard line around repairs.
Decide whether the plan is worth offering
Planned equipment servicing gives the customer regular servicing and gives the contractor recurring work. It can expose wear, blockages and damage before the next unplanned call. It cannot promise lower bills, longer equipment life or freedom from breakdowns.
From your side, test the job before offering it. The work must repeat cleanly. Your calendar must have room for the visits. The price must recover setup, scheduling, reporting and renewal administration. Your records must show whether each completed visit recovered its actual cost.
Do not use a fixed-dollar shortcut to decide whether equipment should be repaired or replaced. Record whether the unit can run, what remains defective, what the repair covers and what the customer can choose to do next. Quote the repair. Let the customer decide.
If you are still setting up the wider business, use the HVAC business setup guide to work through the operating basics before committing to recurring visits.
Inspect the site before promising recurring work
Start with a baseline inspection. Do not price routine maintenance from an equipment list supplied over the phone unless you have enough reliable site information to define the work.
Record:
- Customer name and service address
- Asset identifier and exact location
- Equipment type, make and model where available
- Controls and accessories covered
- Known condition and operating notes
- Roof, ceiling, plantroom or tenancy access details
- Isolation, shutdown and induction requirements
- Occupant, escort or site-contact arrangements
Write locations that a new tradie can follow. North roof beside the stairwell is useful. Main unit is not.
Settle the register before assigning tasks or time. When the roof holds unlisted units, stop and ask the customer which assets are covered. Do not spread the quoted allowance across whatever equipment happens to be there.
Separate the baseline inspection from the recurring allowance. Quote it separately or include it as a defined setup item. Record catch-up cleaning, existing defects and overdue materials as additional work. Do not let baseline labour or catch-up materials consume the recurring visit allowance.
Complete the Australian handoff before booking visits
Ask your state or territory licensing regulator which trade or contractor licence covers the exact work you plan to offer. Check the licensing body responsible for refrigerant handling before including refrigerant work. Write down each answer and keep unauthorised work out of the scope.
Ask the Australian Taxation Office about your ABN, GST and BAS treatment. Show the chosen GST treatment consistently in the quote, agreement and invoice.
Ask the work health and safety or occupational health and safety regulator for the service location about workplace safety duties for access, roof work and isolation.
Set visit timing from the equipment and site
Build the schedule asset by asset. Copy the manufacturer’s required interval from the equipment instructions, then add the site facts that can bring the work forward or require a scope review.
Record these fields for every covered asset:
- Manufacturer’s required interval: [instruction and source]
- Site-condition trigger: [dust, corrosive exposure, heavy operating load or another observed condition]
- Visit tasks: [work due at that service point]
- Due window: [earliest and latest agreed attendance dates]
- Review trigger: [reading, defect, operating change or repeated incomplete task that requires reassessment]
Use the due window to reserve calendar capacity. Do not invent one interval for every unit. Base the timing on the equipment instructions, asset condition, operating pattern, environment, customer needs and the work your business is authorised to perform.
A residential visit may depend on an occupant appointment and access through the home. A commercial visit may need an induction, roof setup, tenant notice, escort or planned shutdown. Those differences change the labour allowance.
Write down who books each visit, the agreed service window and what happens when access fails. Put each accepted window on the calendar before you promise the plan.
Allow for travel, parking, inductions, escorts, roof access, shutdown coordination and reporting. That time belongs to the visit even when the tradie is not touching the unit.
Write an air conditioning maintenance plan by asset
Build an asset work card before the tradie attends. Do not leave the service procedure to be designed beside the unit.
Put these fields on each work card:
- Asset identifier, location and equipment details
- Exact components to inspect
- Exact cleaning tasks and the method required by the equipment instructions
- Reading or test point, unit of measure and acceptable limit from the equipment instructions
- Named isolation point and restart check
- Included adjustments and consumables
- Incomplete-work rule: stop, record the reason and state what must happen before the task can be finished
Give the tradie an on-site sequence that follows the card:
- Confirm the asset identifier and work card.
- Control access and follow the site’s induction, escort and shutdown process.
- Isolate the equipment at the named point where required and within the tradie’s authorisation.
- Inspect every component named on the card.
- Complete each listed cleaning task and use only the allowed consumables.
- Take each listed reading and compare it with the recorded acceptable limit.
- Test operation within the authorised scope.
- Restore panels, controls and the work area.
- Mark incomplete work and record defects, recommendations and the reason the task stopped.
Name the consumables. State whether filters, belts and cleaning materials are included, limited or billed separately. If a belt needs replacement but the quote says nothing about consumables, the office inherits the argument.
Use this copy-ready outline for the customer-facing terms:
Air conditioning maintenance plan Business: [legal business name and contact details] Customer and service site: [customer, address and site contact] Plan period: [start and end] Covered assets: [identifier, equipment type and location] Visit timing: [service windows and booking process] Included work and consumables: [scope and limits by asset] Excluded work: [repairs, parts, extra diagnosis, emergency work and unlisted assets] Customer access duties: [induction, escort, roof access and shutdown arrangements] Variation approval: [authorised contact and approval method] Price and GST treatment: [agreed price and tax treatment] Invoice and payment: [invoice point and payment timing] Cancellation and renewal: [agreed process and review date] Acceptance: [names, approvals and dates]
Use an estimate while the equipment list or baseline condition remains open. Issue the quote when the assets, visit scope and access requirements are settled. The quote template gives you the fields needed to turn that settled scope into a customer document.
Stop defects from becoming disputed repairs
Inspection does not include repair unless the scope says it does. Exclude unapproved repairs, failed parts, extended fault diagnosis, refrigerant work not included in the plan, emergency calls, after-hours attendance and work on unlisted assets.
Give every tradie the same field rule:
- Stop before doing work outside scope.
- Make the situation safe only within the tradie’s authorisation and the site procedure.
- Record the asset, defect and operating condition.
- Tell the approved customer contact what was found.
- Quote the added work as a variation.
- Get approval before continuing.
Keep the service record and variation separate. Finding a damaged component is a service finding. Replacing it is additional work. A recommendation is not approval.
The Oak Street house example is electrical work, but the approval point is the same. R. Chen’s quote Q-1847 at 14 Oak Street was 1,105 for a bathroom exhaust fan and four LED downlights. The ceiling was lined, and chasing was excluded. Extra cable and chasing became an approved 160 variation, so invoice INV-1847 was 1,265.
These are sample currency units, not a rate card. The variation costs are unknown, so do not calculate profit using the 1,265 invoice and the original job cost.
Price the air conditioning maintenance plan from the visits up
Start with the full estimated cost. Include hands-on labour, travel, access time, materials, other direct costs, allocated overhead and plan administration. Do not add markup until every cost bucket is complete.
Hands-on labour: [hours] × [internal labour cost per hour] = [cost] Travel: [travel labour plus vehicle cost] = [cost] Access and coordination: [induction, escort, roof setup and shutdown labour] = [cost] Consumables and materials: [your cost] = [cost] Other direct visit costs: [your cost] = [cost] Allocated overhead: [your consistent allocation] = [cost] Estimated visit cost: [sum of visit costs] Planned visit costs: [sum of every planned visit] Plan administration: [setup, scheduling, reporting and renewal work not already allocated] = [cost] Estimated plan cost: [planned visit costs plus administration] Markup: [estimated plan cost] × [your markup] = [amount] Selling price: [estimated plan cost plus markup]
Markup is added to cost to reach the selling price. Margin is profit as a share of the selling price. Mixing them can leave a quote looking healthy while the finished job loses money.
State the plan period, invoice point, payment timing, access responsibilities, cancellation method and renewal method beside the scope. Name the customer contact who can approve a variation and record how approval will be captured.
Make every visit produce a complete job record
Record the customer, site, asset, actual tradie time, travel, access time, materials, completed work, readings, defects and customer decisions. Keep recommendations, approved variations and incomplete tasks in separate fields, then attach the record and invoice to the correct job.
Job management software for tradies can keep those records together once the manual process is settled. Use the HVAC job workflow to keep the customer, site, asset and completed visit record attached to the right job.
Compare estimated and actual cost after each visit
Cost tracking starts when the visit closes. Compare estimated and actual labour, travel, access, consumables, call-backs, direct costs and allocated overhead.
Find the cause of each variance. It may be an incomplete asset register, restricted access, underestimated cleaning, repeated materials, a tradie process problem or a weak original allowance. Change the cause rather than hiding the extra cost in overhead.
Judge the whole plan as well as each visit. A short visit does not rescue a plan that repeatedly loses time at inductions or roof access. The job costing for tradies close-out guide shows how to separate actual vs estimated cost and test job profitability.
Rebuild the scope and price before renewal
Before service plan renewal, compare the allowance with recorded actual labour, travel, access, consumables and administration. If those costs keep exceeding the allowance, reprice the work, narrow the scope, change the access terms or decline the renewal.
Build the next estimate from the actual quantities recorded on completed visits. Do not bury overruns in overhead. Remove retired assets, add new equipment and rewrite tasks that repeatedly fell outside scope before sending the next air conditioning maintenance plan to the customer for acceptance.
