I was so confirmed that I'll be getting the Mitsubishi Starmex system 3 (5 ticks), until one salesman messed with my mind again.
He said the outdoor unit should not be mounted using brackets, as that causes loud vibration noise when operating. And the neighbours will complain. Mounting the unit on a ledge is ok, as the floor is concrete.
The place where I am going to mount is below 1 of my bedroom window, which is also above my bottom neighbour's bedroom window. Due to the design of the block, the noise will definitely be an issue.
He suggested I get the Starmex 2 ticks model instead, or the new LG 5 ticks.
Now I'm back to square one..
Is he right? Or he just wanna sell more LGs?
