    Not intending to disagree, I will take a different approach based on the last post by OP about cooling.

    I did a little google search about OP's weather. There is a wide disparity between the mean average and high temp for OP's climate. This tells me that a two stage AC condenser could be the answer for this homeowner.

    OP needs a load calc especially for cooling and outside design numbers must be thoughtfully considered.

    IMO

    Thank you again. In other threads on this forum, I've seen professionals refer to the XB13 as builders grade, or only installed for landlords. Can anyone articulate why I might want to upgrade to a different model even if the cost recovery doesn't quite make sense over time?

    People sometimes label the XB13 and XB14 as such, but the truth is they are mechanically equivalent to the XR13 and XR15 with a slightly different cabinet and less sound deadening features. Not bad units at all, just some differences to market them at a lower price point. The XR and XLi models are certainly nicer. The XLi outdoor units are very quiet if sound is a concern, but most new units aren't notably loud usually. The XB300 is the real "builder" model unit in the Trane line. Don't see too many of them around here. Like others, I still would ensure a load calc gets done to ensure proper sizing -- 6.5 tons is a lot of cooling.

    If you want to go with a 2 stage compressor trane just came out with XR16 which may save you some $ over XLi for same performance but if you are dead set on noise then you may be better of with XLi but I have put in both and havnt noticed much precievable differance the XL just look nicer with cover. If it is close to a window make sure the top of an XL unit is a good way below window sill as they tend to be tall units and blow air more horizontaly and if next to window can be an issue.

    Proper load cal. & XR16 is my vote. Then in close 2nd would be a XL15.
