    Confused The proper way to install an evap. coil condensation drain

    Can someone post pictures and description of the "proper" way to install a drain line off of the AC coil?

    do you use both connections?

    Leave the overflow side plugged?

    Use one of those safety switches?

    Do you install a "vent leg"?

    Not sure this is the place to ask - but we have a 1980'ish heat pump/air handler that needs a lower drip pan. The air handler is model: 40AQ024330DF. The problem is: the upper support for the coil is plastic...no problem; the lower tray is base metal...which has rusted through.

    Our "friendly" A/C tech says the trays are no longer generally available, and one can be made for ....$. Either that, or buy a new coil/tray assembly for about $to put in the air handler ductwork.

    What's the skinny on this? Is there no way to buy/have made a lower plastic drip pan for the coil in the unit?

    The PITA A/C folks are gonna check with me about what I want to do. Kick them in the butt for asking $ for a $ piece of sheet metal !!

    Please advise,
    Thanks,

    It's called making a profit. Do you sell your product at or below cost? You can't buy a flat piece of sheet metal for twenty dollars. If you think it's so easy of a job, try doing it yourself, and don't call the PITA A/C folks back. I'm sure they'll be heart broken.

    I spent many years in injection molding. That is plastics. To have a drain pan made in plastic would be around $15k in engineering costs. Probably $100K in tooling costs, plus $1000/hr to run the machine to make it. So plastic is out. On that, I wouldn't put a dime into a piece of equipment made in the 80's. Replace the darned thing. Otherwise, go to a sheet metal shop, have it made and install it yourself. To make one is far from $20, I deal with these guys on occasion and they don't make squat for $20, much less anything as complicated as a drain pan.

    It depends on the setup. There is a forum with pictures here (not the Wall of Shame) that should give you an idea of the proper way. Do you have doubts about the way your drain was installed?

    40AQ Air Handler Drip Pan

    Whoops...two replies look like I hit too close to home in my question...about getting a replacement drip pan for a 40AQ left-hand orientation coil.

    I'm not begrudging anything reasonable...but $x for a metal drip pan is more than NASA would pay.

    I do computer repairs, and if I tell someone it will cost $350 for a new laptop battery for a ten year old laptop, guess what the reply would be?

    All I'm trying to do is to come up with a) a Carrier replacement...charge me $100-200 for it, and I'll do it. A friend who does A/C for a living says a Carrier drip pan is usually about $x...and maybe 1/2 hr to install. That is a heckova long way from $x...or b) coat the remants of the metal pan with fiberglass fabric, and cover it with Bondo. That's a DIY job that wouldn't take more than an hour of time. What's the problem with that?

    You have it all figured out. So why are you asking us? A new Carrier drain pan might be whatever. But a 20 year old one isn't. Get your buddy to get one and you two can make a day out of it.

    Yeah...and that's part of the reason China is cleaning our clock in manufacturing.

    I remember being in secondary school in PA forty years ago, and making things out of sheet metal...with soldering, etc. The Carrier drip pan is NOT an engineering marvel...in fact it looks very much like the base of a window box planter...with a couple of drain plugs.

    This my friend is, or rather, should not be considered rocket science.

    No...I charge reasonable rates of $60/hr. I add 15-20% to the supplies cost for retail buyers. Again, the piece of formed sheet metal weighing about four pounds, that looks very much like a window flower box base for $x. My name is not: Ben Dover

    Sure you can...at Home Depot...2'x4' - 10 gauge...want a link to the URL?

    Ah, were it that easy to let the A/C guys know that asking $x for a drip pan versus $x for a new coil/drip pan assembly, after they already charged me $x for an on-site service call.. this is dumb.

    As to the heart-broken part, if I were concerned about that my friend, I would have done so already just for the excitement.

    Blan "B" is the way to go. Makes me wonder , why didn't I think of that? Get back to us with your results please. Thank You.

    Really guys...I came here for advise...I'm simply asking:

    a) is there any place, or any way of obtaining a new, replacement lower drip pan for my air handler?

    b) if we elect to get a new coil for the air handler, is there anything we should pay attention to.

    And as an aside...just to keep this feistiness going...my "buddy" is someone I met for the first time today...so we're really not that close.

    Then it is odd you would call him your buddy.

    Do not argue with an idiot. He will drag you down to his level and beat you with experience.
