I am a home service technician, and I recently completed a diagnostic on a Goodman heating and cooling system. The system was not producing the desired temperature, so I performed a thorough inspection of the unit. I checked the electrical connections, the refrigerant levels, and the airflow. After identifying the issue, I replaced the faulty component and tested the system to ensure it was working properly. I also provided the customer with tips on how to maintain the system and prevent future issues.
