I have done bending of soft copper tubing before with a bending tool which has 18" long handles and require quite a bit of clearance to operate.
I am trying to replace a 25' run of 3/8" air conditioning copper condensate tubing. Way back when it was first done when they laid the original copper tubings (one suction pipe, one refrigerant line and one condensate line) they did it against the original ceiling, than they ran AC ductwork and built a chase to hide all that.
Here you can see I have cut three holes in that chase where the original condensate line passed through.
Now my question is, if I get a coil of 25' long 3/8" AC copper tubing, starting on a ladder outside the exterior concrete block wall (left side of the picture below) where these original tubing penetrated the wall, if I uncoil the tubing into a straight section and feed it in all the way to "A". There I need to steer the tubing to turn to B then turn towards C and eventually exit the ceiling chase to turn down towards the unit's condensate pump. Is this even possible to run this pipe and bend/manipulate it to make these turns inside the ceiling chase with duct work inside, and have to unbend and rebend as the tubing is pushed forward?
I try to picture how I would do it in my head and my conclusion is this is impossible to do without cutting open the entire ceiling chase to form a continuous path for the tubing.
The other option is to make joints...I don't think I want to solder up there in the tight spot with AC insulation pads and other flammable materials.
Is copper the best choice here? Are there 3/8" PEX I can use for this? But then once it exits the exterior wall it needs to run down to the ground and form a trap for the condensate to discharge. PEX can't be run outdoors.

Copper is so easy to work with that you do not need to use large heavy duty benders. you can use a bender like this one. This one is for 1/4 in, get one for 3/8
