Heating, Air Conditioning, and Refrigeration Mechanics and Installers
Installation, Maintenance, and Repair
Work starts with blueprints and manufacturer specs to see how a heating or cooling system should go together. Circuits are tested for continuity, the unit is connected to its fuel, water, or refrigerant source, and controls are set to the recommended balance. Talking with the user helps isolate a fault; after the fix, the system is checked against the original plans. Upkeep includes cleaning, vacuuming, oiling parts, and changing filters, while keeping the area clean and following safety rules. Fits people who like reading drawings, talking a fault through with the user, and doing the install or fix themselves.
