are there any of you around,I see many traditional plumbers but not of the mechanical services type,ie Installs, maintains and repairs piping, ducting and equipment for heating, cooling and ventilation of buildings or vessels.

was wondering who you applied to for licenses, is it the same as traditional plumbers.

Hubby has done this for 24 years but is going for RPL and to try and convert qualifications.

Someone please answer lol
