trane aluminum i.d. coils

[Trehak01]

I know with carrier you can request for tin plated coils. some of there units came from the factory that way. I dont know about trane or any other manufacture.

Was not aware of that... Will this be a total switch... or offered as an option?

I don't know if they are switching over to it totally, just that it is an available option when ordering the coils.
I've used a couple of them to replace customers existing ADP copper tube coil last year.

Looking at the product literature, it looks like the model numbers for the aluminum coils have a G or B in the 2nd digit of the model number.

In the ones I got, the distributor tubes and suction header tubes were all copper, and were joined directly to the aluminum tubes on the evaporator coil.
I guess we will see how that works out.

IMO, Carrier kinda flubbed with the tin plated coils, the front tube sheet and crossovers are not plated, so will still rust out and leak just as bad as any of their unplated coils.
They are making all aluminum coils now though.

I dont know about trane or any other manufacture.

AS/Trane, and Goodmana, have been using all aluminum coils for a few years.
Some of the 3rd party manufacturers have either switched to all aluminum, or have it as an option on some portion of their products.
