Preformed duct cleaning estimates for client. Client stated that the had mold remediation done in their home and were advised to have their ducts cleaned. I inspected the inside of the unit inside of the attic and found a substantial amount of dust/debris build up inside of the plenum return box and ducts, also found a substantial amount of dust inside of the supply vent ducts as well. I am providing estimates for a level two or three duct cleaning to help resolve the concerns.
