    Have they shown you a print out of the Manual-J (Load calc)? They measure each room, walls, windows, and attic? If your old one was 100k, sounds like they just matched what was already in the home itself.

    Airflow CFM's are reading 1030.


    Your running in comfort mode.

    At 1730 CFM in third stage heat you'll be at roughly .87".
    Allowable, but at the high end.

    I could not see your pics at home but I can see them at work so I am doing a test and reposting them to see if I (and others) can see them.

    Let me know if you could not see them in post 1 but you can see them here.

    I saw them yesterday, today I don't... This is not the only post.. I think there is something wrong with HVAC's host site for the photo?

    I can see the photo when people post it the other way (full view in post)

    Hotwater tank

    I believe you said you had an 80% furnace. Was the flue tied in with the hot water tank? Does the tank flie have a 3" liner in the chimney?
    What was I thinking??? I never do that again!!!

    I agree, I saw them an hour ago in both posts from my home computer....now I can't see them in either.
    Did someone notify the moderator?

    Hopefully they used vanes in the return drop where it connects to the air filter.
    Power humidifiers, don't work real well installed on the return.
    In order to add moisture to the air, they need heat. And there isn't a lot of heat in the return air.
    As others have said, pump up under the outdoor unit would be nice to protect it against snow accumilation.
    Canvas would be nice, and is actually a code. But may not be enforced in your area.

    Other then the humidifier on the return drop, and no pump ups under the outdoor unit, I didn't see anything terible.

    Why do you say 1730 beenthere. The cfm at .5 is 1510 and just wondering where you are getting1730
    Do it right the first time.

    93,000 BTU output, at 50° temp rise requires roughly 1730 CFM.
    At 1510 CFM, it would give a temp rise of 57°.
