    Dog,

    I questioned myself ( per other posts here ) about how focused I was on the ventilation apects and the ducts. But, this installer wasn't short changing me on the quipment, either. I just...

    Oh please rip away.. just hope it is the old ducts and system and not the new lol I'll ask about the financing as the other company had no interest no payments for 12 months. I hate doing that as it...

    I'll get started on the before pix before it gets hot.. not far from hot now :)

    This is where I ended up with my logic. Again, it worked for me but am sure there are other opinions that may be equally valid for other people and their needs. I paid a slight premium for this...

    Dash,

    I kept saying the same thing as I argued with myself between the 2 installers as well as between the levels of complexity. The Zoning guy on a similar equipment install ( no zoning ) would...

    I probably forget more than I should as far as everything they have done and will be doing. One thing I have failed to mention is they will be installing "tents" over my attic access opening as well...

    I just returned from meeting the installer and I have signed the contract. I'm glad I had the old duct system tested to show the leakage rate as it, in the end, proved what I suspect in that I needed...

    Thanks. After discovering how much leakage I have, I'd guess a high speed fan and no AC would be an improvement ( kidding ). I've already spoken with the home CEO ( spousal unit ) about the comfort...

    Thx Beenthere... am hoping to meet with him/them tomorrow morning to discuss. I think we can get to a point where they can install a 2 stage AC ( higher end 16 SEER + 2 stage variable speed 80%...
  10. Flow rate, duct velocity, duct leakage verification post installation

    I'm curious to know how many installers actually perform any of these tests after they have installed new ductwork, of if I am beginning to be too anal about this part.

    Obviously, if a duct system...

    I rarely complain ( too much ) about getting older with exception of the shoulder pain I'm currently experiencing.. but seems my 40+ memory sometimes really kills me ( I prefer to think it's the 40+...

    To all above, much thanks. It seems overwhelming that most prefer insulation on the outside, if properly done . My gut feel is I tend to agree. I did speak with the installer about how they line the...

    Thx Beenthere. I actually have confidence this company will properly account for the friction losses of the lined ductwork. I'd say if anything at all I do beleive they know what theya re doing form...

    Thx Cem Bsee.. it's in the attic so not much I can do about where the ductwork is going to be. I'm going to discuss this with the installer as soon as I receive their quote to see where they are in...
  15. Lined Metal Ductowrk versus Wrapped External

    Still trying to sort through all my options as it seems I have yet to get the perfect quote ( not speaking of pricing mind you ). But, today's quote threw a curve to me as the installers seemed to do...

    Thx Tinknocker.

    I"m still waiting for the quote from the Lennox installaer and am now also waiting for a revised and more detailed quote from the Carrier installer ( namely I want him to specify...

    Won't disagree. I haven't heard much else to suggest the bull part but then I'm not exactly an expert by any stretch. For the most part most of what has been said seems to be on the up and up. I took...

    bmathews.. thanks for your comments. Again, it has given me some room to think it through. Just sounds like the Harmony system is indeed more complex ton properly set up. I'm praying my vent system...

    Thanks Nova.. comments are greatly appreciated. Seems to match closely with what the carrier installer is telling me :)
