You can expect to have cleaner air ducts and you may feel better about
that. In rare cases if you have a mold and/alergy problem related to the
ducts (not nearly as common as the duct cleaners would have you believe) you
may find some relief there. In any case you will find your wallet a little
lighter.

We tried if for my wife's condition. The "good feeling" fades fast as
I had to touch up with pant or clean marks off the wall ...get the
fasteners back in correctly.

A careless bunch of workers. No more duct cleaning for hire. Seeing
the method, they used I can make the tool and do it IF I was ever
inclined to do so.

That makes my wallet heavier.

What does the tool look like? I've never seen it done, but I have
access to both compressed air and a shop vac. I know they drill small
holes in the duct for access, but not what they put through the holes.

What I saw, was a shop vac with an attachment on the end. Ball shaped;
able to filter and allow the dust into the vac (size may vary?).

Appears to be used, also to scrub the duct, as you move it back and
forth. My ducts were cleaned by removing the grill , shop vac back
and forth through the duct with the attachment.. They could only go so
far, so that adds to my thoughts - I can do this. Last time I moved
the washer/dryer I vac-out the dryer vent pipe of combustibles.

It would depend upon the size of the system, but I don't think a shop
vac would pull enough suction. At my place, the guy had a big vacuum
unit (still 120 V, but external motor with a belt drive to the
blower), it had a bag about 4' diameter. This stayed in the back yard.
The hose from it was 10" dia (wearing several duct-taped scars of
battle), and he inserted it into an opening in my furnace output line,
about a foot from the furnace (there is a vent there, although it is
usually shut). Then he snaked a compressed air line into each supply
and return register and shook it around. All this produces an
impressive noise, and no doubt cleans the ducts some too.

In addition, they have the most important piece of equipment which is
the camera on a leash in the briefcase with the LCD monitor. This is
where they show you the before and after video. The after is quite
clean, and you have to assume that the more inaccessible places in the
system got flushed to some extent.

I got this done just before they hauled away my old furnace and
installed a new one, so I wasn't too concerned about crud falling into
the coil and blower and other innards in the heat of battle, but I
imagine you have to be careful about that in other circumstances.
