Tumpany tanya here

The bedroom at second floor (2 storey terrace) is in need of new aircon replacement. Currently using non inverter from more than 10 years old

The problem is with concealed piping (within walls i think) and the outdoor units was installed on the middle roof (the place where water tank also placed there) for aesthetic reasons

If upgrade to inverter aircon, is it easier to put new piping/wiring outside and put the new outdoor unit into new place (like wall outside) rather than redo the concealed piping? Can i leave existing piping and odu alone when installing the new one. Because the newer gas and inverter replacement will implies new piping as is upgrading from very old to newer model

Mine was a 7 year old+ aircond replacement in Dec last year. Had to change piping because old air cond use R22 gas. All new aircond use R32 gas. The installer said its a must to change. Had to hack wall abit in my bedroom.

What is the reason for changing the pipe? Due to diameter, thickness or material required?

Newer R32 ones operate at 60~70% higher pressure than R22. If you use old pipes , it will leak. And R32 refrigerant is a little flammable , so dont take the risk
