When installing an industrial AC system, an AC technician typically performs the following tasks:

  1. Site Evaluation & Assessment:

    • Conduct a thorough evaluation of the industrial facility, including the size, layout, and specific cooling needs.
    • Assess the electrical and structural setup to determine the best placement for the AC units.

  2. Load Calculation & System Design:

    • Perform heat load calculations to determine the correct size and capacity of the AC system required for the industrial space.
    • Design a custom cooling solution tailored to the needs of the business, considering factors like equipment heat output, employee occupancy, and the building’s insulation.

  3. Ductwork Installation & Modifications:

    • Install or modify existing ductwork to ensure efficient air distribution throughout the large industrial space.
    • Seal and insulate ducts to improve energy efficiency and minimize air leakage.

  4. Indoor Unit Installation:

    • Mount and secure large indoor cooling units, such as air handlers or evaporators, in appropriate areas like utility rooms or ceilings.
    • Connect the indoor units to the duct system and make necessary electrical and refrigerant connections.

  5. Outdoor Unit Installation:

    • Position and install the outdoor units (condenser units) in a location that allows for proper ventilation and clearance.
    • Ensure the units are placed on a solid foundation, such as a concrete pad or elevated mounting brackets.

  6. Refrigerant Line Installation:

    • Run copper refrigerant lines between the indoor and outdoor units.
    • Insulate the lines to reduce energy loss and prevent external damage.

  7. Electrical System Setup:

    • Make electrical connections between the AC units and the building’s electrical system.
    • Install a dedicated power supply and connect the units to the electrical panel, ensuring the system complies with local codes and safety standards.

  8. Gas Line & Ventilation (if applicable):

    • For systems that use gas-powered components (e.g., gas furnaces), the technician will connect and test the gas line.
    • Ensure proper venting of exhaust gases for safety and efficiency.

  9. System Commissioning & Testing:

    • Start up the system to check that all components are functioning correctly.
    • Test the cooling capacity, airflow, temperature controls, and humidity management to ensure optimal performance.

  10. Leak Testing:

    • Perform leak detection on refrigerant lines to ensure there are no gas or fluid leaks.
    • Pressure test the system and confirm all connections are secure and leak-free.

  11. Final System Calibration:

    • Calibrate the system settings, including the thermostat and temperature sensors, to ensure accurate and efficient cooling performance.
    • Set up energy-saving features and optimize the system for maximum efficiency.

  12. Safety & Compliance Checks:

    • Verify that the installation meets all local safety codes and regulations.
    • Ensure proper electrical grounding and that all equipment is safely installed to avoid hazards.

  13. Customer Walkthrough & Demonstration:

    • Walk the facility managers or business owners through the system, demonstrating how to operate and maintain the AC units.
    • Provide recommendations for regular maintenance and offer a guide on troubleshooting basic issues.

  14. Post-Installation Inspection:

    • Conduct a final inspection to ensure the installation meets all quality standards.
    • Clean up the installation site and remove any debris or leftover materials.

These tasks ensure that the industrial AC system is installed efficiently, safely, and ready to provide consistent and reliable cooling for large commercial or industrial environments.
