Why are you replacing your compressor ?
Why are you replacing your condenser ?

You asked a very specific question.. and got specific answers based on recent experience....

However, I am worried about the bigger picture... since you do not mention replacing the Reciever/Dryer , possibly needing to flush the system due to the reason you needed a new compressor....

Since you do not sound like you have the specialized tools /experience to do this... you may be better off having that machanic you mentioned do this job... as I am assuming he was including these almost de rigueur* items in his labor estimate.

and yes,,, I understand that the combination of " almost" and 'de rigueur" together is an oxymoron *.
