I was wondering if anyone in here has used any of those outfits that
clean your air vent/air duct cleaners who brings a big truck with a
pop up roof?

I've been calling around for estimates and information and from what
I gather there are those who use a hose to send down your hot air
vents and cold air returns to blow with compressed down to your
mainlines to which the vacuum hose would be attached and suck out
the dust.

Another type, supposedly more thorough cleaning, is first sending
down a rotating brush down the hot air vents, then use the hose with
the compressed air. I was told that they don't brush the cold air
returns because sometimes there are electrical wires and cables
running through them.

Do these types of duct cleaners really work to reduce your household
dust and would the brush method be that much cleaner? The places I've
called are all registered with the local BBB and have good records.

Thoughts? Thanks for your time and courtesy.

Total waste of money for 99% of the population. Furnaces and AC have
filters which can keep ducting clean for years. For the $$ you will be
overcharged, you can buy dozens of super duper ultra high performance
furnace filters. Duct cleaning is one of those legal but foolish
businesses that are basically a feel good operation. If dust is a
problem in your house, it isn't from dirty ductwork. The dirt or dust
arrives from elsewhere, like fibers from cheap carpets, animal fur,
poor clothes dryer venting, etc. Look around, find the source(s),
correct them, instal good filtration and change filters often. Take
the money you will save and treat your bride to a fabulous weekend at
the nearest posh resort in your area.

I believe there is an EPA site that says pretty much the same thing.
