cleaning duct work

[pianotuna]

Hi,

Any ideas how to clean duct work in an RV?

Very carefully. If you knock it loose somewhere underneath, then you have a job taking the underbelly off to get at it to put it back together. For the most part trailers use the same mylar flexible ducting as a residential home does so it is fairly tough and can stand some abuse while cleaning. The way they put trailers together though I would be concerned about other damage.

As far as the duct cleaning business goes, I worked in HVAC before and attest to the validity of it. A friend just had it done in his older 70's home and they took out 7 lbs. of dirt. Yeah, it builds up.

Spray some Lysol into it kills mold.

Are these true ducts or Styrofoam channels? If the latter all a brush will do is tear up the Styrofoam. If they truly have mold in their ducts, the only successful remediation is to replace the ducts and likely the entire system. And if mold is in the ductwork, it's in other places as well.

And it even smells good!

The inquiry is being made for a friend in Florida. Molds are a real issue there.

Don, as long as you didn't spill a pound of butter in there, shouldn't be too bad to clean! :W:W:W

I would get an inspection camera first.

I just replaced all the ducting in a 50 year old home as it was old, broken and unfixable. Ducts were made of this fibrous material (almost like fiberglass) that would seem to trap a lot of dirt and dust. Perfectly clean inside. Starting to think much of the duct cleaning business is a hoax chasing the boogie man.

Remove the vent cover. Get a section of flexible hose for your vacuum and duct tape it onto the vacuum hose. A 4" vent brush on a drill works to loosen stuff up, but usually not needed.
