Why each item is on the list
The RTA number. The ARC requires Refrigerant Trading Authorisation holders to put their number on quotes, invoices and receipts. It starts with AU. A licensed technician who isn't working for an RTA holder must include their own licence number, which starts with L.
Model and size. With the brand, model and kW in writing, you can check the energy label and the size against your room yourself.
Electrical work. Mitsubishi Electric says a unit needs a dedicated power supply. A new circuit that isn't on the quote becomes a surprise later.
Certificates. In Victoria, you must be given a Certificate of Electrical Safety and a plumbing compliance certificate at the end of an installation.
Signed at the kitchen table?
Asking for a quote doesn't make the installer's visit invited. If a deal is negotiated on that visit, it can be an unsolicited consumer agreement, with a cooling-off period that runs to the end of the 10th business day.
During that time the supplier can't take payment or do the work. Our cooling-off guide explains when it applies.
Warning signs on any quote
- No RTA number anywhere on it.
- A size in kW with no word on how it was worked out.
- A refrigerant top-up with no leak test or repair. The ARC says topping up first is illegal.
- A request for payment on the same day as an in-home sales pitch.
What we'd do
What we'd do
Run the checker before you sign, then send the installer the list of anything missing and ask for a revised written quote. A good installer should be able to add most of it quickly, since it's paperwork they already hold. If you haven't got a quote yet, the quote form is where to start, and licence-checked local installers who do your kind of job will see it.
