I've come down to the part of my selection process where I'm seriously evaluating options and choices. I've pretty much decided on Trane XV95 furnaces for both systems--it was either that or the XV80, and my local gas company is offering a rebate on 95% furnaces that make the upgrade to the XV95 a no-brainer.
We live in central Arkansas, so AC is a necessity, not a luxury. After looking at all the ways I could spend large amounts of money on Trane's upper-end bell-and whistle condensing units, I've come to my financial senses and am looking at more moderate options without going I'll-regret-it cheap. (As we all know, the low bid isn't always the best value.)
Right now, I'm looking at the XR13 vs the XR15. I know the XR15 has a little better SEER number, but as far as I've been able to determine the difference isn't enough to save me huge bucks on my electric bill. The XR15, of course, costs a bit more. However, there is a modest rebate from Trane through the end of the month. I know prices are forbidden here, so I'll just say that with the modest rebate the price difference is small enough that I wouldn't let it keep me from buying the more expensive unit if there is a compelling reason to do so.
The warranties are the same. They even look the same (in the pictures I have, at least). Is there a compelling reason (reliability, quality, performance, etc) to go with the XR15 over the XR13?
One last thing as long as we're talking compelling reasons. Without going to the significant expense of a 2-stage condenser, is there another model in the line that pairs particularly well with the XV95? Some compelling reason to pop a little more for that option? I have limited funds and am looking at two systems, so it's gonna be a chunk of change, but I'm willing to stretch a little if there's a compelling reason to do so (other than a salesman looking for better commissions, that is).
Any real-world experience or insight is appreciated.
