Upon arrival, I first inspected the unit for heating issues and an airflow fault. I began by examining the air filter for clogs and cleaned it if necessary. Next, I checked the evaporator coil for dirt and debris, ensuring it was free from obstructions. I adjusted the fan speed from medium low to medium high to enhance airflow. I also opened a register in the basement to facilitate better air circulation. Additionally, I measured the gas pressure, which was slightly high, and adjusted it accordingly. Finally, I conducted a check for CO2 leaks in the supply air. The system is now functioning correctly.
