I don't know. Is the process you're referring to supposed to remove all of the impurities in the line after brazing? Isn't there some kind of filter built in to the system that does this?
The condenser often has a factory installed drier, likely due to factoring in some measure of protection against installs where evacs and nitrogen purges were skipped. But it's not a panacea. If it were my house and I let it go this far I would want to see the installer return, recover the refrigerant, install a liquid line drier (using a nitrogen purge during brazing, and ensuring that the new drier is R410A refrigerant rated if that's what's in the system), evacuate the system down to 500 microns, weigh in the proper charge, and check for proper operation afterward.
But that's just me. Especially after, with a bit of field mileage, you've seen more than your share of overcharged systems from installation forward, no nitro purges or evacs of linesets prior to charging, and no liquid line driers installed on a changeout...
...and you understand the consequences of each or all of those steps being skipped.
Overcharge = diminished efficiency and capacity/shortened life of compressor due to extra load and possible washing out of oil from compressor bearings due to liquid floodback
No nitro purge during brazing = debris left in system to clog metering devices or harm compressor windings
No evacuation = moisture and non-condensibles left in system that will diminish capacity and efficiency. Moisture reacts with refrigerant oil to form acids, which in turn eat at the insulation on compressor motor windings. Non-condensibles increase compressor head pressure and reduce efficiency while increasing power consumption.
I know firsthand of systems that were properly installed, evacuated, and charged that have lasted over thirty years on the original compressor with adequate maintenance. Those that are not are lucky to push ten, if that much, without compressor problems.
Compressors don't die, they're murdered.
