  • Inspect the condensation line looking for any obstruction.
  • Inspect the outdoor unit to confirm that everything is in order and that the area is clean and free of debris.
  • Do a lubrication check and perform any replacement needed.
  • Visually examine the air filters to determine whether they need to be replaced to maintain the desired airflow.
