    I really don't think they will show up in the Evap. Coils....
    That said Goodman, Trane and others have fin coil that are aluminum.
    So that may show up soon in ref. ?
    Nordyne already has micro channel a coils in their air handlers.

    Carrier went to all aluminum micro channel on com and industrial equipment. Didn't go very well. They have discontinued for now. It is going that way across the board though. They just got to work out the kinks. Heatcraft has also gone to the micro channel on cond coils and seem to be holding up better then carrier's version.

    I was talking comm. ref. here...
    We have put in several MC inside and out Nordyne units. No problems yet....

    Only thing we had was a Nordyne coil replacement last year. They gave us a MC replacement on a HP. Replaced by the book even changed the bi-flow, vacc. Etc. in the end of the cool season. Three months later the piston/strainer in the CU was plugged.

    The coil had something in it.

    I took a tour of the Trane Factory in Clarksville, TN last year. Not only will the coils be all micro channel, an engineer there told me that the refrigerant lines will eventually be as well. Its a matter of economics. Cost of aluminum vs the cost of copper.

    There are some Commercial Air Conditioning systems out there which are starting to use Aluminum Tubing as opposed to Copper Tubing.

    What about the push for manufacturing out of recycled aluminum? As in car engines? My mechanic explained that the impurities from recycled aluminum has made it the material softer therefore requiring a milder anti-freeze which will not eat up the aluminum castings.

    I'm calling BS on that one. Scrap percentage effects steel not aluminum. They have been remelting recycle aluminum a long time.
