Diagnostics and Repair

• Troubleshooting: Identifying electrical circuits, component failures, or mechanical issues using multimeters and gauges.
• Refrigerant management: Checking for leaks and recharging systems safely under ⁠EPA guidelines
• Component replacement: Fixing or swapping out worn motors, compressors, valves, and wiring.

• System adjustments: Calibrating thermostats and balancing airflow to optimize energy use.
• Duct and filter care: Inspecting and cleaning air ducts, vents, and filters to improve air quality.

Customer Service and Compliance

• Communicated system issues to clients, presented repair or replacement options, and provided efficiency tips.
• Documented job details by logging hours, recording parts used, and writing digital service reports for accurate record-keeping.
• Pre-Installation and PlanningReview blueprints: Read technical diagrams to plan the layout of units and ductwork. Site prep: Inspect the work area, remove old equipment, and ensure safety. Load calculation: Check building specifications to verify the proper system size. [1, 2, 3, 4] Core Installation DutiesMount equipment: Secure furnaces, compressors, condensers, and air handlers indoors or on roofs. Run ductwork: Install, seal, and insulate air ducts for proper airflow. Make utility connections: Join copper refrigerant lines, gas pipes, and water lines. Wire systems: Connect low-voltage and line-voltage electrical wiring to thermostats and control panels. [1, 2, 3, 4, 5, 6, 7] Testing and Customer ServiceTest performance: Run diagnostic checks on airflow, electrical circuits, and refrigerant pressure. Code compliance: Ensure all work meets local building codes and safety regulations. Educate customers on thermostat operation and HVAC system maintenance to enhance user experience.
