Duct cleaning to remove dust, dirt, debris, and other contaminants from the ductwork. Application of a disinfectant to eliminate mold, bacteria, viruses, and other harmful microorganisms that may be present within the ducts. Cleaning of air vents and registers to prevent the recontamination of the ducts. Had to adjust vent count due to 2 returns not leading to anything & fully insulated once grille was removed. 1 supply had the duct removed & unable to run hose through as it wasn’t connected at the boot from previous company who installed it. Completed duct cleaning on 24 supply vents & 3 returns.
