Manifold Gauge

Term from Air Conditioning Services industry explained for recruiters

A manifold gauge is an essential tool that HVAC technicians use to check and service air conditioning and refrigeration systems. It's like a doctor's stethoscope for air conditioning units - it helps technicians measure pressure, add or remove refrigerant, and diagnose problems in cooling systems. When you see this term in a resume, it shows that the candidate knows how to properly test and maintain air conditioning equipment. Other names for this tool include "refrigeration gauge set," "HVAC gauge set," or "AC gauge set."
