After some 11 years of service, my Daikin Super Multi System 4 finally failed on me last Sunday.
I intend to replace my aircon with either the Starmex or Toshiba System 4 as the current Daikin Super Multi (R410A based) is just too expensive.
Now this is my dilemma, should I change my air-con copper piping and the insulation material which is already 11 years old?
70% of my piping are concealed and if i do change the piping it would be a major rework!
Anyone facing the same problem before and if so how do you choose which way to go?
Thanks for the feedback.
