Aircon Gas Pipe Leakage

[Jits 0]

Hi Gents,

Recently done my house renovation, but post renovation one of the Aircon unit has gas leakage. The Aircon maintenance guys tells me the gas pipe is leaking and I need to hack the walls to fix the leakage ! OMG, I got a shock,hack the newly renovated home ?!

The Aircon guy then told me there are some vendors who can seal the gas pipe leakge by spraying some gum through the pipes. Does anyone has any experience fixing the gas pipe leakage w/o hacking ? Any contacts ? Also I suspect the Aircon pipe was damaged during my reno. Shouldnt my ID take some responsibilty as I suspect the gas pipe was damaged during the kitchen reno.

Thanks for some advise here.
