The dealer who also carries Trane was trying to switch me from my original Lennox preference, stating that the Trane coils, which are 100% aluminum, rather than the Lennox coils, which use aluminum fins and copper tubing, provide a better, longer lasting design.
He felt that Trane was superior in other ways also, since they used "composite plastics" in the outdoor condensing unit case rather than steel to ensure that no corrosion or rusting would occur.
The basic claim was that Trane, using aluminum for all of the refrigeration loop, had a longer life expectancy that Lennox, given the newer Puron refrigerant.
Does anyone have any experience with Trane, and is there any science to support this type of claim or any other prior experience to say that Trane is somehow better?
Thanks for any advice.
