Compare Sunshine Coast aircon quotes by scope, licence and exclusions, not just price
A good aircon quote states the exact unit, kW capacity, pipe run, drainage, electrical work, warranty and licence details. A cheap quote that leaves out a $400 circuit, $350 wall bracket or $900 scaffold allowance is not cheaper once the variation lands.

What a compliant written quote should say
For small service work, a simple written quote or work order can be enough. For residential building work over $3,300, Queensland expects a written, dated agreement with the contracting parties, licence number, site address, scope, price or pricing method, timing, specifications and cooling-off information where required. Air conditioning sits inside domestic building work when it is supplied and installed as part of a home improvement, so the paperwork matters.
In plain English, the quote should let you compare like with like. "Install split system in lounge" is not enough. A useful quote says something like: supply and install a 5.0 kW reverse-cycle split, back-to-back wall install, up to 5 m of pipe, wall bracket, drain to garden bed, dedicated circuit by licensed electrician, commissioning test and old unit disposal. That detail is what stops a $2,300 quote becoming $3,100 on the day.
For a bigger ducted job, compare the ducted scope line by line: number of outlets, zone count, return-air position, duct insulation, controller, roof-space access, outdoor unit location and noise risk. If one quote is $2,000 lower but has fewer zones and no electrical allowance, it is not the same job.
What is usually excluded and charged later
The common variations on Sunshine Coast installs are not mysterious. Long pipe runs cost more because copper, insulation, trunking and labour all increase. A condensate pump may be needed where gravity drainage cannot run to a legal discharge point. Double-storey homes in Buderim or Mooloolaba can need scaffold or safer roof access. Older homes can reveal brittle wiring, no spare switchboard capacity or asbestos eaves. Coastal homes around Kawana, Coolum and Noosa may need better outdoor stands and corrosion-resistant fixings.
None of those are dishonest when they are listed honestly. The problem is a quote that wins on price by excluding predictable items. Ask each installer to state the variation rate before you sign: extra pipe per metre, extra electrical circuit, pump, bracket, old unit removal, roof access and disposal. You can compare these numbers against the pricing guide and the cost calculator before approving.

Deposits, licences and checks
QBCC deposit guidance is specific: 20% maximum for work valued at $3,300 or less, 10% for $3,301 to $19,999, and 5% for more than $20,000, with limited exceptions for substantial off-site custom work. A standard split or ducted aircon install is not a reason to pay the whole job upfront. Payment on completion is normal for smaller service and repair work.
Check the QBCC licence register for the contractor and the right mechanical services air-conditioning and refrigeration class. Check the refrigerant licence through ARCtick. Check electrical licensing through the Queensland Electrical Safety Office if the quote includes a new circuit or hard-wired connection. A split-system installer with refrigerant credentials still cannot legally perform unrestricted electrical work unless they also hold the right electrical licence.
One honest constraint: the cheapest quote can be the right call if the scope is identical and the installer is properly licensed. We do not tell homeowners to pay more for the same work. The trap is assuming two one-line quotes describe the same job when one includes electrical, drainage and disposal and the other does not.
How to compare quotes in 10 minutes
Put the quotes side by side and highlight the model number first. Then compare capacity, install type, electrical allowance, pipe length, drainage, access, old-unit disposal, warranty and deposit. If you are in a unit or townhouse, add strata approval and outdoor unit location. If you are near the beach, add condenser corrosion protection and clearance for airflow. If the quote is for a repair, compare diagnosis quality against our aircon repairs page and the refrigerant leak detection guide.
The quote you want is not necessarily the longest one. It is the one that answers the expensive questions before work starts. That is the paperwork that protects you if the system is noisy, drains badly, is undersized, or fails a warranty claim because the install was not documented.
