Looking for a bit of guidance. A/C blows warm hot air. Compressor doesn't even kick on. Took it to local mechanic as I am out of my element on A/C systems. He tried to charge it and said it wont take a charge at all. He believes the whole system is shot and recommends new compressor/ dryer/a/c collection/ condenser/ and all new lines. He believes there was water in the system and it rusted/rotted out. He said a blacklight shows Freon has leaked Everywhere on the a/c lines.

A little back story is this car has sat (In an enclosed building) for 15 years. He said we are looking at 1200ish dollars for new everything. After some sluething I can by a new dryer tube/compressor/seals/a/c collector for around 200 bucks off amazon new. If I include the condenser we are at 300ish. I am mechanical and feel comopetent to replace it all and have him charge my system for me once the work is done (for approx. 150 bucks)

My question is, should I take him at his word and order it all and replace, or start with the compressor, dryer tube and seals? What all lines would I need if I replaced the lines?

Any insight is much appreciated!
