Can air duct cleaning cause damage?

Cleaning air ducts can cause significant damage that can be costly to repair. The ducts are made of various materials. You or an unqualified duct cleaner may not know how best to clean ducts made of certain materials. In addition, you could damage them if you use the wrong cleaning materials and procedures.

Duct cleaning is a service offered by most HVAC companies. However, cleaning the air ducts can do them more harm than good. Most Houston residents choose to clean their air ducts because they have old ducts that have been in the attic or inside walls and that have collected dust for more than ten years. Most air conditioning companies will promote duct cleaning as a solution to improve indoor air quality, but they don't mention that this service can cause significant damage to duct systems that will need to be repaired in the future.

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. As long as cleaning is done properly, there is no evidence to suggest that such cleaning could be harmful. The EPA does not recommend that air ducts be cleaned routinely, but only when necessary.

However, the EPA recommends that if you have an oven, stove, or chimney that burns fuel, they be inspected to make sure they are working properly and serviced before each heating season to protect against carbon monoxide poisoning. A heating and air conditioning professional can thoroughly check the ducts to determine the type of ducts and the condition of the different hooks and safety points. Failure to do so could damage the ducts, reducing efficiency and, in addition, could cause premature system failure. For example, the rotbrush can quickly become trapped in flow dampers and break or disconnect poorly secured or protected ducts. Damaged ducts are often the result of air duct cleaning, especially when done by an inexperienced contractor.

This is because much of the dirt that can accumulate inside air ducts adheres to duct surfaces and does not necessarily enter the living space. Some cases in which it may be appropriate to use sealants to encapsulate duct surfaces include repairing damaged fiberglass insulation or combating damage caused by fire. in the ducts. There is a great risk that the fragile plastic layer will break when these air ducts are moved to be cleaned years after installation.

These products are specifically designed for use in ducts or as ducts themselves, and are tested in accordance with standards established by Underwriters Laboratories (UL), the American Society for Testing and Materials (ASTM) and the National Fire Protection Association (NFPA). In addition to removing unwanted dust and allergens, cleaning air ducts puts ducts at risk of dents, ruptures, or leaks out of the system. Whether or not you decide to clean your home's air ducts, it's essential to commit to a good preventive maintenance program for minimize pipeline pollution. However, according to the Environmental Protection Agency (EPA), cleaning air ducts has never been proven to actually prevent health problems or effectively remove dust and dirt from ducts.

When service providers visit your home, ask them to show you the contamination that would justify cleaning the ducts. One of the few independent studies was conducted in the 1990s by the Canadian Mortgage and Housing Corporation (CMHC), when it analyzed 33 homes in Montreal before and after pipeline cleaning. However, there is little evidence that cleaning only the ducts improves system efficiency. Under most circumstances, dust is harmless and cleaning air ducts could create major problems, such as duct damage.

Since every home's conditions are different, it's impossible to generalize about whether cleaning your home's air ducts would be beneficial or not. So why do some local air conditioning companies offer duct cleaning services? How can you remove unwanted allergens and contaminants from your home and air conditioning system? If you think cleaning your ducts might be a good idea for your home, but you're not sure, talk to a professional.
