    The air which comes out to heat the house will be loaded with dust and dirt.

    While that's great, there's also dust and dust mites settling into the air ducts. Unless the ducts are cleaned from time to time, the dust and the mites will be part of what you breathe in. ... *Mold and Mildew: Condensation can set up in the duct system and leave behind enough residue to trigger the growth of mold.

    It could cause a fire. Especially if you are talking about your clothes dryer, air ducts.. But for most furnaces, there's not a problem.

    You can get a dust and debris build-up in the lower areas. It is worth doing every ten years. I have mine cleaned when I bought my house and changed the heater.

    Truthfully, your air ducts rarely NEED to be cleaned. They are a closed system for the most part. The most you'll end up with is dust.  A good furnace filter takes care of most other things. That's what they're for. 

    And those companies that tell you different are scamming you. Seriously. They charge a mint for 'cleaning' something that is probably not even needing to be cleaned.

    Dirt will accumulate and you'll grow tomatoes. That is, if a random tomato seed happens to float by.
