Home Vac did my place, and boydid they ever earn their pay.
they pulled just pounds of lint and dog hair out of the registers.
they used a skipper and the giant truck vacuum, plus blew high pressure
air down the vents.  it's still not that efficient, 4 months later
we had to move a vent line and found junk the vacuum had not pulled out.

it helps,  but it isnt perfect.  BTW they give a discount for repeat
customers because there is no setup, and i think it was only $250
for the first time.  they run ads in the bethesda gazzette.....
