Was a new receiver-drier or accumulator put on when the compressor was replaced? 3. Were the expansion valves or office tubes inspected – cleaned – replaced? 4. Were lines inspected / replaced? 5. Was the condenser and evaporator checked/cleaned of debris to be sure there is a free flow of air through them? 6. Was the system properly vacuumed down? 7. Check and use the OEM recommended amounts for the type of oil needed. 8. After filling system with Freon, was the compressor hand turned to avoid hydro lock? 9. Was the voltage checked at the compressor for required the voltage to avoid clutch failure? 10. Was the system run and checked for leaks? 11.
