I conducted a comprehensive diagnostic on the Goodman HVAC system, starting with a visual inspection of all components. I checked the thermostat settings, wiring, and control board for any irregularities. Next, I tested the electrical connections and assessed the airflow to ensure proper ventilation. I also examined the condenser and evaporator coils for any signs of wear or damage. Finally, I ran a series of operational tests to verify the system's efficiency and identify any potential issues. The diagnostic revealed no major problems, but I provided recommendations for routine maintenance to ensure optimal performance.
