I performed a comprehensive service on a Mitsubishi mini split heating and air conditioning system. First, I inspected the outdoor unit, ensuring it was free of debris and properly secured. I then cleaned the unit to remove any accumulated dirt or grime that could hinder performance. Next, I accessed the indoor unit to clean the air filters, which were found to be clogged, and replaced them with new ones to improve air quality and efficiency. I also checked the refrigerant level, ensuring it was within the optimal range for efficient operation. Finally, I tested the system to confirm that both heating and cooling functions were operating correctly. This thorough service should enhance the system's performance and longevity.
