Air Duct Cleaning is the Search the List category for members (both paid and free membership classes) to find well-rated and reviewed companies which do this.

You can also find information on air duct cleaning, and on when it is or is not recommended for heatlh purposes - look in the Home > Air Duct Cleaning link under Browse Projects, at lower left.

You will find some responses and links there about the need for air duct cleaning - certainly if your ducts are molding or mildewing up (which also indicaters an incoming air moisture or A/C evaporator operational/cleaning issue) cleaning is recommended for health.

Also, if they are getting significantly clogged such that airflow is being restricted then they should be cleaned - and the air filtration looked at because if you get enough to clog ducts in less than 20-30 years you have too much dust and lint coming through the system, so the filter layout/location needs to be looked at to see why so much lint/dust is in the system. (Usually a poor design that recirculates the return air without filtering it, so household lint and hair and such pass back into the furnace (which also clogs the heate xchanger and A/C evaporator coil) and then builds up on the duct walls.

Duct cleaning is also called for at times if the dust buildup in the ducts has been knocked loose by construction activities or significant earhtquake or sometimes a major rapid air pressure change like a tornado passing over, causing the dust to be mobilized and ejected from the supply ducts - although frequently just taping some fiberfill quilt batting arched up in a dome over the affected supply ducts for a few days will control that adequately - just be sure you do not block the supply vents so much that the blower fan on the furnace changes speed/sound tone noticeably.

However, and this will undoubtedly bring some screeches from air duct cleaning companies, especially those who recommend annual cleaning, research has shown that just having a visible but stable buildup of dry, not moldy dust in the ducts is not a health problem - in fact, a slight buildup on the duct surfaces actually reduces the amount of dust and hair making it through the system because that acts as a surface filter - gradually catching and building up more and more dust, meaning less is getting into the house hold air. The big air quality issue is usually the amount of dust circulating in the house, which better primary air filters in the furnace/air handler handle best - in many cases one filter for the furnace makeup air, another in the primary airflow return duct before it goes into the furnace/air handler. (A lot of systems put the air filter on the supply duct right after the furnace, but this means the air is not being filtered BEFORE it reaches the heat exchanger, so dust builts up in/on the heat exchanger, which reduces its heat transfer efficiency and over many years can also reduce the airflow able to get through it.
