Hi Rina,

The duct cleaning business is often associated with corruption. However, there are good quality duct cleaners out there.  I have used Len's Carpet Care & Consultants for about twenty years.
This year I asked them to evaluate the need in my home for duct cleaning.  I think it was more than ten years ago that I had it done.  They came to my house with a telescopic camera and put it in the duct work.  They showed me the live shot and told me that the ducts looked good and that they didn't need cleaning.  There
was no charge for this evaluation.  And that's how it should be.
Their number is 517-886-5367.
