I am trying to re-arrange a couple of air cons in my house because getting rid of very old ones. So will be shifting a 12k btu to a 18k btu slot in my dining room.

The aircon contractor told me not to re-use the pipes meant for 18k btu for a 12k btu. The piping seems to be working well. It will be seldom that this 12k btu will be used (at most 1-2 hours/week).

Is there a need to get a new set of piping? Anyone can kindly offer 2nd opinion?
