Manifold Gauge

Term from HVAC Services industry explained for recruiters

A manifold gauge is a basic but important tool that HVAC technicians use to check and adjust air conditioning and refrigeration systems. Think of it as a diagnostic tool, similar to how doctors use blood pressure monitors. It helps technicians measure pressure in air conditioning systems, detect leaks, and add or remove refrigerant when needed. Without this tool, technicians wouldn't be able to properly service air conditioning units or ensure they're running efficiently. You might also hear it called a "refrigeration gauge set" or "HVAC gauge set."
