Compressor
A compressor is a key piece of equipment in air conditioning and refrigeration systems. It works like the heart of the system, moving and pressurizing the cooling substance (refrigerant) that makes air conditioning possible. When you see this term in a resume, it usually refers to someone's experience in installing, maintaining, or repairing these vital components. There are different types, such as scroll compressors, reciprocating compressors, and rotary compressors, but they all serve the same basic purpose of helping create cool air in AC systems.
