    Confused Looking for ansewers..

    I was hoping someone might have an ansewer to a problem I'm having with an American Standard coil. The coil to this unit has been replaced 6 times and is needing to be replaced again. Thank goodness for the extended warranty. My A/C man tells me that he doesn't know what is causing the failures with each one but they all develope leaks in less than a year. We live in Pleasanton Texas. We are just your average family with no use of anything I can think of that might cause this thing to keep failing. It is a 3.5 ton heat pump unit with the air handler in the attick. The unit is now 8 years old and I think must be a lemon. It was one of American Standards fancier units when we purchased it. I would appriciate any input. Thanks.

    6 coils, Really, 6 coils. I think mister A/C man is getting a kick back on that warranty. I would be draging a factory rep up to that attic if I couldn't figure out why the 2nd one died.

    This sound really fishy.

    If your lucky someone with intimate experience with AmStd will read this and have a magic answer, other wise I would call another A/C guy for a second opinion as long as that extended warranty will allow someone else to do the work.........
    If sense were so common everyone would have it !

    Have you been shown any leaks to date? If no, why not? Hard to believe, six coils in a row are bad.

    Indoor coil or outdoor coil??

    American Standard units have the spine fin coils and the roto-lock compressors.....

    Might not be the coil....might be the roto-lock fittings that are leaking....
    I need a new signature.....

    Thanks for all the advice. No I have not been shown where the A coil is actually leaking. I have been up there with him when he used his sniffer. I am going to call American Standard and see if I can get someone else out to look at it. I have always thought it strange that all they would do is just keep replacing these coils, the folks at A S, I mean. You would think they would become curious as to what is going on. My A/C man says that he has several of these units in other houses and that this one is the only one they have seen this problem with.

    Thats really odd, i was an American Standard dealer for years and although i did not like the coils i never had any problems with them.
    Could there be something in the home or attic, fumes????? That would degrade aluminum?

    Six coils… please ... in thirty-five years I have not had six bad evaporator coils. There was some blown in insulation that was causing problems years ago ... so ... maybe ... but chemicals eating up a coil would not be covered by the warranty. Also after a few why would they keep replacing them instead of the complete a/h. Maybe the leak is because the suction line is porous and that is why he gets a hit in the attic … maybe …

    The attic does have the cellulose insulation blown into it. It was purchased at Home Depot back in late 2002 the same year the a/c unit was installed. Is there any more info on that problem that you can expand on. Thanks.

    Same contractor do the original installation, as well as all the repair work?


    I'm guessing, a bad install from the get-go.

    AS coils

    13 year dealer 2 bad coils.American Standard coils are the highest performing coils on the market when it comes to pressure drop and sensible heat removal. My 2 bad coils had plugged distributor tubes, no leakers yet.

    A classic case of technician error, if its too dumb to be true then it isnt, there is no way you had 6 bad coils.
