Had to work on a RTU today for the one resturaunt we have under contract. Turns out the bottom half of the evap was frozen and circuit 1 suction line all the way to compressor. Thinking the problem was in circuit one I disabled it and ran circuit 2. Immediately after coming on the compressor pulled into a vaccum. I also noticed that several of the feeders immediately frosted over. Each feeder seems to have its own metering device so I assumed that the frosted ones had restrictions. After 2.5 hours of coil defrosting I finally disabled circuit 2, ran circuit one, added about 2 pounds of freon, and left them above freezing for the night. I told them they need to replace the evap coil, am I on the right track here? Thanks for your comments.

Why just sell them an evaporator coil? I'd try to sell 'em a condenser coil along with another compressor. Heck, I'd sell a used car too.

Seriously,
First, find that refrigerant leak, recover the unit's refrigerant charge, repair that leak, install a new liquid line filter drier, evacuate the system using your vacuum pump and then weigh in the manufacture's recommended charge by weight (it's on the unit's data plate).

Did you find a leak in the evap that is beyond repair? Hope you said it in a way that doesn't cause them to get a second opinion. If it is not in the evap as you have told them then when company XYZ shows up and fixes it considerably cheaper then it may cost you the account. With our current national economy even regular customers are shopping.
Customers may get annoyed by not giving an answer right off but they respect you when you only give the one correct answer and not 3 different ones.
Sorry to hammer you a bit if it pumps into a vacuum its usually flat or a complete restriction
