Applying heat, with a heat gun, to the compressor

Heating the compressor with a heat gun helps turn any trapped liquid refrigerant into vapor, making it easier for the recovery machine to remove that refrigerant. When liquid refrigerant remains in the system, the recovery unit struggles to capture it efficiently; warming the compressor speeds up vaporization so the unit can pull it out as vapor, increasing the amount recovered. This is why warming the compressor can improve recovery. It isn’t about warming ambient air or having no effect—the ambient air won’t reliably vaporize liquid inside the system, and the idea that heating is prohibited isn’t accurate. Used safely and briefly, a heat gun applied to the compressor can aid recovery by vaporizing trapped liquid.
