Thanks for the advice. I am also seriously considering changing everything now. Better do it during reno. Dont have to go through hassle again..though it will be an extra cost right now ! Also the old aircon become yellow !! looks dirty. Hopefully can get some trade-in discount for old aircon..
How much extra does it cost to change piping?
