Anyone ever had air ducts cleaned. If so, who do you recommend?

Great question I was also thinking about getting my ducts cleaned. Hopefully there are some good recs.

Depending on age of your home, I would give some consideration to reducting the house vs cleaning the existing. The cleaning process can cause more leakage and in the past years there has been major improvement in the insulation of ducts and controlling air loss. Also gives you the chance to rebalance if you have a hot or cold room. Just a thought.

Most houses built even remotely close to this decade have flex. I have no idea what they run down that to clean it but I sure as hell wouldn't want to try it out.

I just treat duct dirt like asbestos...Not a problem until you start dicking with it.
