I've been told by a professional that I need to replace my 6 yr old split system unit. He said that the pipes have apparently changed size so it means I will have to replace all the pipe work to the unit. I'm on the ground floor of a 3 storey block of apartments so have been quoted a bomb for the work. Is this really the case with regard to 6 yr old pipes and is there any adaptor or something that could fix the problem?
Thanks for your help in advance!
