What are the cons of duct cleaning?

Cons of cleaning heating ductsYour air filters should already keep dust out of the ducts. You risk damaging your ductwork if you don't hire the right contractor. On the other hand, if a service provider doesn't follow proper duct cleaning procedures, duct cleaning can cause problems with indoor air. For example, an inadequate vacuum collection system can release more dust, dirt, and other contaminants than if the ducts had been left without problems. A careless or inadequately trained service provider can damage ductwork or the heating and cooling system, which could increase heating and air conditioning costs or force you to perform difficult and expensive repairs or replacements.

While the debate over the usefulness of regular duct cleaning continues, there is no evidence to suggest that such cleaning is harmful, as long as it is done properly. You may consider cleaning air ducts simply because it seems logical that air ducts get dirty over time and should be cleaned from time to time. The process of cleaning the ducts that carry air to and from the HVAC is called air duct cleaning. The EPA does not recommend that air ducts be cleaned, except when necessary, due to continuing uncertainty about the benefits of duct cleaning under most circumstances.

Duct cleaning methods vary, although industry associations concerned with air duct cleaning have established standards. Only technicians qualified in inspecting and cleaning air conditioning systems can safely clean ducts and expel air to the outside of the house. Knowledge about cleaning air ducts is in its early stages, so a general recommendation cannot be given as to whether air ducts in the house should be cleaned. Duct cleaning is not considered a necessary part of the annual maintenance of your heating and cooling system, which consists of regular cleaning of drain trays and heating and cooling coils, periodic filter changes, and annual inspections of heating equipment.
