+name: heating-ventilation-air-conditioning-and-refrigeration-engineering-technician
+description: "Occupational skill for the role 'heating, ventilation, air conditioning and refrigeration engineering technician' (also: air conditioning technician, HVAC project technician, HVAC systems technician, HVACR technician). Use when the user asks for typical heating, ventilation, air conditioning and refrigeration engineering technician work such as: Test electrical circuits or components for continuity, using electrical test equipment.; Repair or replace defective equipment, components, or wiring.; Discuss heating or cooling system malfunctions with users to isolate problems or to verify that repairs corrected malfunctions."
+---
+
+# Heating, Ventilation, Air Conditioning And Refrigeration Engineering Technician
+
+Heating, ventilation, air conditioning and refrigeration engineering technicians aid in the design of devices which provide heating, ventilation, air conditioning and possibly refrigeration in buildings. They ensure the equipment complies with environmental standards. They handle hazardous materials used in the systems, and ensure safety precautions are in place.
+
+## Core workflow
+
+1. Test electrical circuits or components for continuity, using electrical test equipment.
+2. Repair or replace defective equipment, components, or wiring.
+3. Discuss heating or cooling system malfunctions with users to isolate problems or to verify that repairs corrected malfunctions.
+4. Connect heating or air conditioning equipment to fuel, water, or refrigerant source to form complete circuit.
+5. Install, connect, or adjust thermostats, humidistats, or timers.
+6. Comply with all applicable standards, policies, or procedures, such as safety procedures or the maintenance of a clean work area.
+7. Study blueprints, design specifications, or manufacturers' recommendations to ascertain the configuration of heating or cooling equipment components and to ensure the proper installation of components.
+8. Install auxiliary components to heating or cooling equipment, such as expansion or discharge valves, air ducts, pipes, blowers, dampers, flues, or stokers.
