    No carpet here, I guess I could have some wet concrete to deal with. Attic, they get a overflow pan, but not this. On second thought, we very rarely put one in an attic. Furnaces don't belong in an attic.

    Combining the coil and fau drain without a trap and vent for the coil puts a positive pressure in the fau drain line when the blower is running. This was not designed to happen or tested by the factory. Hopefully fau drains ok.

    I always add a safety overflow switch for reasons stated.

    Nice work.

    The furnace drains into the same drain. Just a 1/2" cpvc fitting slid inside the 3/4" sdr21.

    Plenty of room for pressure to blow by. Plus if the drain stops up I won't have any acidic water getting to the coil.

    Very nice install.

    +1 on the forming of the lineset. Very clean looking.

    As for the condensate float, the inspector flagged my 1st floor unit (downdraft) for not having a coil pan float... Upstairs unit is in the attic and has a secondary float switch. Inspectors vary in what they deem code. Otherwise, AWESOME install.

    Hmmm...
    Which makes more sense to you?
    CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
    ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%

    DO THE NUMBERS! Step on a HOMESCALE.
    What is comfort? Well, it AIN'T just TEMPERATURE!

    Energy Obese? An audit is the next step - go to BPI.org, or RESNET, and find an auditor near you.

    No, I don't use mastic unless it is in a crawl or attic. Furnace and both supply and return duct are in the same conditioned space. Doesn't matter.
