I conducted a comprehensive heating and air conditioning repair service for a client. Upon arrival, I assessed the system to identify any issues. The heating unit was found to have a malfunctioning thermostat, which I replaced to restore proper functionality. Additionally, the air conditioning system was experiencing refrigerant leaks, which I located and repaired. I also cleaned and inspected the ductwork to ensure optimal airflow. Throughout the process, I maintained clear communication with the client, explaining each step and the importance of the repairs. The job was completed efficiently, ensuring the system operates at peak performance.
