Look for a NADCA approved duct cleaner. I used to sub out to a couple of different duct cleaners in town. They both did a good job. I hooked up with our only NADCA cleaner in town. I will never go back even though he is 15- 20% more on each job. He is more thorough than I have ever seen and he documents all of his cleaning. He also realizes that if the furnace filter does not seal properly, then his job is not done. Definitely check these guys out. I was impressed.

Just read beenthere's post. The guy I use will call in a service company if coils or blowers need cleaning. I have also seen him walk away from a job where the duct really didn't need cleaning. As with just about anything else, find someone you trust and make them prove what has been done.
