I repaired a Trane XR16 HVAC unit today that was experiencing airflow issues. The homeowner reported that the system was struggling to cool the home. Upon inspection, I found that the blower motor capacitor had failed, which was causing reduced airflow. I replaced the capacitor with a new 45/5 MFD dual run capacitor and tested the blower motor to ensure it was functioning properly. Additionally, I cleaned the evaporator coil to improve efficiency. After verifying the refrigerant levels were within the recommended range, I ran a full system test. The unit is now operating efficiently and cooling the home effectively.
