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.
You may consider cleaning the air ducts simply because it seems logical that the air ducts get dirty over time and that they should be cleaned from time to time. You may consider cleaning air ducts simply because it seems logical that air ducts get dirty over time and need to be cleaned from time to time. Duct cleaning is not considered a necessary part of the annual maintenance of the heating and cooling system, which consists of the periodic cleaning of the drain manifolds and heating and cooling coils, the periodic replacement of filters and the annual inspection of the heating equipment. 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. The process of cleaning the ducts that carry air to and from the HVAC is called air duct cleaning. 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. While the debate over the value of regular duct cleaning continues, there is no evidence to suggest that such cleaning is harmful, provided it is done properly.
Only technicians who are qualified in inspecting and cleaning air conditioning systems can safely clean ducts and expel air to the outside of the house.
