    I looked up the coil, it's around 17.5" X 17.5" X 21.5" so the furnace could be a 40,000 to 60,000 just looked bigger to me.

    Looking at the pic... looks like B width (17.5")...

    If so, and if the chart on the link is accurate...

    Then 4 choices. Probably is either a 40K or 60K...
    We do not as of yet know what AC unit the installing contractor planned to use... so my guess is the 40K/3T drive.

    If we get a pic of the furnace guts... we can count the burners...

    *Installation is more important than the brand of equipment
    *The duct system keeps the house comfortable; the equipment only heats and cools (and dehumidifies)
    *Cheap is not good, good is not cheap; however expensive is not a guarantee of quality!
    Choose your contractor wisely!

    Flex duct is not a bad thing (it has a bad rep)... as long as it is installed correctly.

    What I would be concerned about with the supply plenum... is it having internal insulation... which has in the past been a 'petri-dish' for organic growth...
    We use metal plenums... we seal all the connections, then wrap them with insulation. Do not see any insulation on that one...

    The mastic (white or grey, clumpy paint) holds the tape in place... tape does not stick to mastic... so the tape goes first.
    Mastic should be 2MM thick (think-ness of a nickel-- $0.05)... general rule of thumb: if you can see through it, it is not think enough. Its best quality is holding things together and plugging holes.
    All these things, of course, are labor intensive... which raises the price of the work.
    Better, IMO to get it done now... than later!

    Good thing... is most of your ductwork will be accessible later... if something needs to be done.
    I have read here about installing the flex correctly, pulling it tight, not compressing, not looking like an octopus. Interesting about the supply plenum, didn't know that, love learning something new. I will look the next trip, oh and ask for the information, too. I knew about mastic, learned that here.

    Actually, the builder called the stop until I decide what I want. I wish he had run the equipment by me before letting it get installed.

    Advise: make a list of all the issues... you are gonna need it...
    I did not know that about the foamed roof and the condensensing furnace and PVC vs metal pipe. I am making a list, You'all have contributed to that list. Thanks, and I know I need it.

    The guys spraying the foam are completely covered in Tyvek suits with respirators, and full face masks. So there saying there going to pull the flex away while they foam? BS
    All that should come out as well as the furnace and coil.
    I am going to verify that with the builder and get it in writing. I agree it needs to come out, foam and then do the installation. Good advice and I appreciate the heads up.
