Most AC tune-up jobs we perform break down into three parts:
Visual inspection: Your technician will thoroughly inspect the exterior of the unit and visually examine key components like the blowers and belts. They'll look for signs of rust, corrosion, or other damage, and if they find any, they'll inform you and recommend repairs - ultimately, though, you have the final say over whether or not they perform those repairs.
Cleaning and maintenance: After the inspection, your technician will perform basic maintenance like replacing air filters and fixing minor problems. They may also recommend cleaning dirty interior 44 like coils and fins as needed to prevent wear and damage to your machine over time.
Performance testing: Before calling it a day, your technician will run the air conditioner and assess each component to ensure that your system and everything in it are operating as they should!
