I think it is VERY beneficial to the company that does it. Their kids need
college and braces, too.
I'd do it, or get a grunt to go into the attic and other spaces with the
air running, and make sure all the seams and connections are tight. Take a
roll of the GOOD foil tape. Take a screwgun and a handful of pointy one
inch screws with the 1/4" head. I'll bet you will be surprised to find how
many downright leaks you have. And places that weren't put together all too
good in the first place.
The ducts would have to be pretty closed up to the point of restricting air
flow, and if that was the case, you would already see dust or crud three
inches deep on all your furniture, carpet, etc.
Consider this. They do have dust in them. The dust came out of the
air. The dust is still there. They are collecting more dust than they are
putting back into the air. It sounds like unless they have set some kind of
record and the dust is blocking the air flow, I would leave well enough
Duct cleaning made me real sick for days since the dust is caked in.
Cleaning them loosened all the crap I breathed, and yes they used a
10000.00 vac cleaner , clean your furnace and AC coil, to reduce
airflow should be impossible with ductwork, I bet its the AC coil and
dirty blower wheel .

There are several factors to consider and questions to ask yourself.
How old is the house/ducts?
How old is the furnace/air conditioner or air handler?
How long ago was the unit (not duct work) serviced?
How frequently have the filters been replaced (or cleaned if permanent
You may want to start with a professional inspection and cleaning of the
furnace and a/c equipment, including the heat exchanger and cooling coil.
There could be some blockage there, as well as in the air handler. Even if
the ducts still need cleaning, this equipment needs to be kept very clean to
avoid problems. If there's no problem there, the service people may have
other recommendations before you proceed with duct cleaning.
The ducts would have to literally be filled up to prevent proper airflow, and
is probably the least of your problem, unless they are extremely old.
The wife is complaining that her allergies are worse at home now.
When she's out, they're not so bad. She thinks it's the vents. What
else do you think could be causing it? Or who should I call out to
investigate the cause of the problem?
