Arrived for duct cleaning estimate. Inspected duct and counted total supply and return vents for both suites. Client expressed concerns for musty smell in both suites. We discussed duct cleaning vs chemically cleaning and eliminating odor source from the evaporator coils for each roof top unit. Created and sent over estimate for deep cleaning of units. Suite 102: s-22, r- 14 101: s-33, r-14
