Beginning with the refrigerant level, I conduct a thorough inspection of the outdoor unit, ensuring optimal levels and making adjustments as needed. The cleaning process follows, removing dirt, leaves, and debris that could impede airflow and compromise efficiency. My attention then turns to the base pan, where I inspect for blockages in drain openings, eliminating any obstructions to prevent water damage and mold growth. Moving on, I examine the coil and cabinet, performing necessary cleaning to uphold efficient heat transfer.
