I received a phone call from a client who wanted to schedule a duct cleaning for Friday, November 5 between 8 and 10. I scheduled the appointment and provided the client with a confirmation number. I arrived at the client's home on time and performed the duct cleaning service. I used specialized equipment to clean the ducts, including brushes, vacuums, and air whips. I also checked the air filters and replaced them if necessary. The client was very satisfied with the service and thanked me for my professionalism.
