Now that I have heat with blowers that actually move air, it keeps blowing out crap. I thought it would stop, but it's not really stopping. It's this black foam like coating that is lining the heat ducts that is disintegrating and spewing this black grit every where. Fine black sand like Anyone ever experience this? Best procedure to remove? Or can it just be painted or coated to stop the disintegration, you just touch it and it crumbles, it turns to powder as you press your finger into it instead of being elastic like foam should be. Best replacement materiel or does it need to be replaced? It's an insulation but is it more for sound or heat or both? Anyone that has dealt with this before please advise me on the correct solution. I love how when you work on problem a, that Leads to a problem b and then a problem c and so on and so on and so so on.... | ||

This doesn't sound like a stock material, but something that has been added by a previous owner? Your shop type vacuum cleaner and a method of agitation to remove would be about your only choice. Immobilizing it with some sort of spray is likely to make trouble in the future, and then it will be in uncontrolled size chunks and harder to remove. Yup, nothing breeds more jobs than a coach, except maybe an old boat, or an old airplane, or maybe an old car. Good thing we do this for fun? happy coaching! buswarrior | ||

foam on the inside of heating ducts would minimize the condensation during AC use. Only way to fix this right is to remove all of it from all the ducts. Imagine the foul stuff in those ducts from years of use. Even if you remove most of it, you are still going to be getting crap blowing out in the future, even though it will be less. It'll be a pain to do, but you'll never regret it, especially as far into the coach($$$)that you are. | ||

Scott If you have a good sized compressor take an air line and a blow gun that you can lock in the on position. Ad a piece of very flexible rubber hose to the outlet of the blow gun. As you are vacuuming out the ducts from one end, feed this air hose in from the other. The flexible rubber hose will beat the hell out of the insides of the ducts so that the old insulation breaks up to be vacuumed out. Hope it helps! | ||

you could probably buy one of those small inspection cameras to monitor your progress. I think Harbor Freight has something. Those Dryer cleaning kits that are attached to a battery drill might be helpful. | ||

You may have to consider a "Tube Scrape-er" which is nothing more that a circle of metal or plastic slightly smaller than the duct you need to clean. A hole in the middle of the circle & a small EYE-Bolt to attach a cord or rope to, once the cord has been threaded thru the duct, pull the scraper thru with the cord while you have the vacuum sucking the garbage up on your end . A wire wheel for a 6 inch Bench Grinder or appropriate sized wire wheel might also scrape the ducting clean . fwiw.. they've worked for me in the past . | ||

Hard way to deal with constipation Jack! Most people just use fiber but not you! You need a wire wheel.  | ||

I never was a "Soap Retriever" but I'll admit that when I left the ship I left my buddies behind... I thought "backdoor" humor was just something only 4104 & Transit owners possessed, been proven wrong twice tonight & from both sides of the border . Does that make it 4 times or 3.4 ? I guess I ass-umed wrong...eh? btw... shineytop who put enough fuel in your tank so that you can go you cruisin for a brusin so blithly ? (Message edited by Jack_fids on February 26, 2012) | ||

We use the stock floor/wall ducts on our '06. The low power output from a 42,000Btu propane furnace does not blow like the stock dual 80A blowers. On the drives side the duct is used for return air for the air cond, again not much velocity. FF |
