Trane versus Rheem
I live in Phoenix, and am fully replacing my 16 year old Trane 4 and 5 ton units. I have bids on both Trane and Rheem from very good contractors. Trane units are 16 seer 2 stage cooling/heating. Rheem units are 15.5 seer 2 stage cooling/heating. All other elements of the proposals seem to be the same, except Rheem has 2 years labor versus Trane at 10, and Rheem heat exchange warranty is 15 versus Trane at 20. Rheem has a 3 year PMA versus 1 year on Trane. Package pricing is 32% more for the Trane units versus Rheem. Neither the Rheem tech or Trane tech could tell me specifically what the difference is between the Rheem and Trane units. While I sense Trane may be a bit higher quality, I would like to know what the justification is to spend that much more. Any help on telling me what the difference is in quality would be greatly appreciated.
