BMW Repair: Evaporator, freon, models

Question
How much labor will it take to replace the evaporator and dryer unit. Is a job that anyone can do/

Answer
I would need your model and year to give you a time. Its a very big job on most models and you will need to have the freon evacuated with the proper equipment. Other than that it can be done but it is very involved and will take a lot of time, but nothing is really hard.
