Just got quoted $15,000 to supply and install a 5kw Split system

I knew it wasn’t going to be cheap considering I’m in a 70’s double brick apartment on the 3rd story, but $15,000?!?! My jaw nearly hit the ground.

Has anyone else received a genuine quote like this, or was the tech hoping I was stupid enough to accept it? He also asked if my neighbours would mind the noise if he started tonight (yes it’s currently 7pm on a Sunday)which I very quickly shut down.

I will certainly be getting other quotes…
