I am still trying to decide between Trane and Ruud. I am leaning towards Trane since I know more about it, and it is what I selected for my downstairs hvac.

My Trane question is this: my downstairs unit is the XL1200 for a/c and XE80 for gas furnace. However, on the Trane website, these units no longer exist. For those of you who sell Trane, what are today's equivalent models?

My SEER question is: for 10 vs 12 SEER, is it worth it to go to 12 SEER? I thought that my original quote for both the Ruud an the Trane systems was 12 SEER, however, when I got the faxed details Friday it is for 10 SEER. From the Trane perspective, it seems that the 12 SEER units (like I have downstairs already) have the 10 year warranty, vs the 10 SEER having a 5 year warranty. Plus I like the closed top cabinet on the a/c on the XL1200.
