    This indoor coil needs to be replaced due to non-repairable refrigerant leak.

    The furnace will have to be removed to drop the coil so it clears the door jamb.

    The air filter cannot be pulled straight out without hitting the right side of the door casing. Bending filter is the only way to manuver it in the filter base.

    Gas flex penetrates cabinet

    High voltage to furnace has no retaining clamp

    Base of furnace hangs over filter base edge allowing large return leak in closet. Also there are very large air gaps around the supply plenum where it penetrates the closet ceiling.

    No secondary condensate drain protection.

    The return air opening (grille size) is only 16x30 for a 5 ton blower & outdoor unit.

    Wood bracing supporting floor broken and weak.

    Blower housing screws gone.

    Reversed polarity

    Thermostat wires hanging down in the way of the filter.

    Thermostat "Y" was wired to "G" so the outdoor unit ran when fan-on was selected.

    Supply air grilles installed backwards in kitchen.

    No return path in Master Suite area.

    Furnace flue pipe touching combustable wood decking as it penetrates the roof.

    One flex duct in attic supported by stat wire.

    No start capacitor yet the indoor coil has a TXV.





    Please advise on suggestions to correct these problems.

    Now that I think about it I bet the installers were limited on space because of the 2" riser the plumber penetrated the floor with for the condenstate drain. It was either move the drain to the left or just install the furnace further over to the right......

    Just guessing.

    walk away --
    gonna cost as much as new unit --

    however, I would put all of this in writing to the customer!
    you do not want any liability if hazards cause fire --

    or, T&M = time & materials, with a base price --

    Bet, it was passed by inspector,and homeowner has 1 option to make builder call hvac contractor back and make repairs, or small claims court.

    Is that combustion air square duct?

    1) pull furnace
    2) new floor /plywood and bracing
    3) repair/replace coil
    4) Install furnace/coil in middle of closet with offset to plenum
    5) seal/duct/re-pipe drain
    6) Collect big check/and have inspection done by city with pictures after.

    You never know. The customers might be so distrustful of the original contractor,
    they might pay Steve's company to have a new system put in.

    If the TXV is the bleed-through type, and most are, then no start cap is needed. Should not need secondary drain pan, not located in attic.

    WHY get involved in an obvious mess that will be more timing consuming than one can initially define and STILL BE "the scapgoat" in the end!

    Challenges are fine ..

    this looks like a great opportunity for
    taking a tool
    and wacking yourself with it
    after 3 hours on the job.

    WALK AWAY is a reasonable choice.

    But it should have a float switch on the secondary drain connection.

    Secondary drain protection is required by code "where damage may result". Doesn't have to be a pan, can be a float switch or wet switch.

    I am recommending the wet switch because the float switch won't protect if the pan cracks.

    I think the best solution is going to be replace the gas furnace with electric heat AHU. Move it left just enough to clear the door jamb. Will need to relocate the drain penetration in the closet floor. It's going to be expensive but what else do you do? The attic is not very friendly, space wise, due to high vaulted ceilings so relocation to the attic is not going to be a reasonable solution.

    are there any real trademen left or just hacks. i blame the freaking inspectors and the builders to let this happen. one thing i was taught coming up was taking pride in what you do. there is a lesson to be learned here any guesses? if you do this charge dearly and explain what needs to be done the correct way. nice house.
