Applying heat to the compressor during recovery

The main idea is that heating the compressor during recovery helps ensure all refrigerant is captured by turning any liquid that may be trapped in the compressor or oil into vapor. Recovery machines pull in refrigerant as vapor, so warming the compressor makes it easier to vaporize and vapor be drawn into the recovery unit, increasing efficiency and the amount recovered. This is a practical technique used to avoid leaving liquid refrigerant behind and to speed up the process, provided it’s done safely and per equipment guidelines. It’s not required for every recovery, and it can be dangerous if done improperly, so use controlled heat and follow manufacturer instructions.
