My York air conditioner which is about 15 years old needs to be replaced soon. I live in a condo whereby the copper piping is concealed in the wall.

Is there any brand/model of new modern air conditioner which can reuse my existing copper piping?

It will be a great hassle and disruptive for me to hack the wall to change the piping.

Thank you in advance dear Sifus...

R32 pressure is 1.5 times higher than R22, leak is going to happen when you use pump R32 gas in R22 pipe

If TS wanted to save few hundred ringgit and bet the leak wouldn’t occur in few years, just wish good luck.

FYI, many Aircon installers in Malaysia use low quality pipe, and many installers don’t follow standard installation set by Aircon manufacturers.

If you think your current old Aircon uses high quality pipe and high standards installation, then go ahead and take the risk.
