Hi all 79 kakis, I"m new here, and I'm facing a problem here with my renovation, which I need some advice. My package includes installation of a System 3 air-con, but the installation by the sub-con is really very ugly. Initially he told me that since compressor ledge is just outside the living room, he hack a hole through my living room, causing a block of ducting in the middle of my living room wall. Not only that, the running of the ducting is so un-organized. I came across one of the household with piping to 2 toilets, but mine only 1 pipe to toilet. Can someone please advise what should I do? If possible, can someone share some photos that you have done in your house? Thanks in advance!
