    Confused Is this unusal for a Carrier install?

    The evaporator coil does not match the dimensions of the furnace, it's actually larger than the furnace, so apparently some type of "adapter" needs to be fabricated. ARI#3233041 Is this good practice? Thanks for the help.

    That's the only Carrier CNPVP coil I see listed as a matchup for that furnace and a/c (the furnace is only 70k btu, so its a small furnace). It does qualify for the tax credit, 13 EER and 18.1 SEER. I see no problems making a clean and professional adaptive fitting to connect to the coil; you're only looking at a 2-3" difference in width. While it's best to have matching widths, in this case it wasn't really possible. Certainly isn't "unusual."

    That coil shouldn't be installed on top of that furnace. Unless all of it over hangs on the left side.

    Or, a transition is used to raise it off the furnace.

    Apparently, they're just attaching with metallic tape, no kind of sheet metal, coil directly on furnace. It hangs over on right side, and is not centered.

    Tends to cause air flow problems.

    If the picture is telling the story, looks to me like the 3rd slab of the N is getting little or no airflow. That's why been said it has to overhang on the left.

    Sorry, not impressive

    Have it fixed before paying for that job that look real bad.Not to mention the airflow problems your going to end up with.It may even leak water from the pan under the coil.I fire someone if they did that on one of my job`s.I would be suprized if it passes inspection by city.

    I'd rather see a transition from the furnace to the coil about 4 to 6" long so air flows across the entire surface area of the coil.
    That picture right there is going to kill your efficiency.

    And from the looks of the transition on top on the coil. They had the room to have it over hang on the left.

    For both the A/C and the heat.

    I agree with the other posters. You'd better scream long and loud now, especially if you haven't paid yet. I doubt the inspector will be any help. At least they wouldn't be around here because we see crap like that all the time. If it isn't corrected now, you'll pay for it each and every month for the life of the system, not to mention the other problems some have mentioned that might come up.
