Have a proper electrician deal with it, get your money back from the people who fitted it, and never use them again.

That is not an acceptable solution for crappy workmanship.

Sure you can. This is a fixed, dedicated load and most sensible regulations require such to have dedicated circuits. It is, however, a fairly small load in this case.

Wot he said, it's a shoddy job and needs to be re-done properly.

Wouldn't have much if any confidence the rest of the install was done properly either.

I had a 3.5kw unit installed for the garage a few years back and they used the power from the power point. I was curious as well back then and IIRC you had to have an isolator switch (AS/NZS 3000:2007 Clause 4.19).

Attached a pic of my install. (I think it was AUD1350 installed for the Daikin Cora 3.5kw, back to back)

That is the correct way .
As per HVAC code of practice.

Thanks.
No isolator switch on mine. Only way to isolate is the 20A breaker for the power points which also takes out half of my house.
