In many cases when we come for air duct cleaning service, we discover various issues that an air duct cleaning can not help. For example, quite often we are getting calls for lack of air flow through some of the vents. However, when we go into the attic to complete the initial inspection we realize that parts of the air duct are old and torn apart. Or in some other cases, we discover asbestos in the attic and in the ducts, therefore, we can only advise the customer for replacing their air ducts.
