i have paid him 1/3 so far... and he has been very conscious of doing the right thing so far.
i hope he does the same when it comes to the liner
he says he'll drain the condensate from the A/C to outside - but the humidifier is the one he wants to drain in the basement french drain.
as far as the liner - I don't think he tried hard enough - he did not use any proving nose cone (even as a layman I could tell that was one thing that was needed).
i will suggest trying to break mortar up is also a great idea...
as far getting it through the bend - he has already sealed the flue-pipe from the furnace indoors with concrete - not sure how he is going to attach the liner to the flue.
thanks again for the advice...
i could mail you a gift card...and i mean it.
