I am a skilled professional that works for a Alaskan Air Conditioning & Heating - Tucson company. I was recently assigned to perform maintenance on a Lennox system. The system was located in a residential home and was experiencing issues with the air conditioner. During the maintenance process, I began by inspecting the unit to identify the problem. I checked the electrical connections, the refrigerant levels, and the airflow. I also cleaned the air filter and the evaporator coil. After completing the maintenance, I tested the system to ensure that it was operating properly. I checked the temperature and the airflow and made any necessary adjustments. I also provided the homeowner with instructions on how to maintain the system in the future. Overall, performing maintenance on a Lennox system was a challenging but rewarding experience. I was able to identify and fix the problem, and the homeowner was very pleased with the results. I am looking forward to completing more maintenance
