As it is right now it comes up from the dryer for about 5 feet, 90 degree turn for 6 feet, 90 degree turn and then striaght 22 feet to the outside.
One alternative is to rerun it straight up from the dryer (the dryer is in the basement) and run it up and after making a new hole, vent it outside. It would end up venting underneath our deck.
The first guy said he could do that and he would use metal duct work, not the fliexi stuff like we have now. Quoted anywhere between 200-300 dollars.
Second guy very thoroughly inspected our current situation. He also fixed part of our problem which was a lot of duct tape that had been wrapped and re-wrapped over a part of the flexi-duct was kind of "plugging" part of the duct straight up from the back of the dryer. He patched with a metal, peel off back tape. Anyway, he said he can do the re-route but his concern was that since it would be venting under our deck we may end up with 2 problems. Number 1, accumulation of lint which after rain and other weather could result in a mildew odor. Number 2, our a/c compressor is next to the deck and could potentially "suck" in the lint and end up with a/c problems.
His suggestion was to keep current layout and replace flexi duct with metal duct. His quote for either fix was $175.
My husband wants a 3rd opinion since these 2 seem so different. 1st guy was balking about fire hazard, etc. but never mentioned problems with odor, a/c. @nd guy was actually quite impressed with the air flow out of the vent with our current situation but felt that the metal duct would improve it by about 20%.
Will you be our 3rd opinion? Oh, the 2nd guy also said he could still vent under deck if we want and run some sort of an extension to the end or the deck so that it doesn't accumulate underneath. Any help you give is appreciated. I'm hoping to get this dont before I get my ducts cleaned which will hopefully end the unexplained dust in my sons room. Thank you.
