I'm not sure why everyone is saying that duct cleanings don't do anything. Absolutely they work! The key with duct cleanings is you pay for quality. If a company shows up with a dry vac, then guess what, your ducts aren't cleaned. But if they show up with a negative pressure machine and have agitators with pressurized air in each one of your air ducts. Then you will pull a TON of dust and debris out of your ducts. The thing people forget is, if you have a dust problem, you have to install something that helps out your air quality. Its almost pointless to do a duct cleaning without installing something to change your air quality because your ducts will just end up the way they were again.
