So the compressor on my home AC unit s*** the bed. The Warranty company sent out a service person who identified the problem. They ordered a new compressor and it'll arrive soon. My problem is that they new want to use virgin R22 in the system instead of recycling the existing freon. 8 lbs for about $560.00. My main concern is that they are just doing this to increase the amount of money they make off the job. The system is not going to be purged, so any leftover "stuff" in the system will still be in the evaporator and the condenser. They didn't even say anything about replacing the dryer. If, when the compressor grounded out, it scattered metal flakes into the system and contaminated the freon I can see the need for replacement. But I also think at that point flushing the system would be necessary (if it's even effective at all). I would think a replacement of the entire system would be more worthwhile at that point.. Is this common practice? The Existing AC unit is about 15 years old.
