I couldn't tell the sound diff between high & low anyway. The swept wing blade is quieter, cheaper, nothing to go wrong.
I don't blame Trane's relationship with big orange for cheapening of any product. The entire industry is responding to John Q. Public's demand for the cheapest price they can get. Only way to do it is cheapen the product.
What's the best made furnace? A ThermoPride. What's the most expensive furnace? A ThermoPride. What's the least sold furnace? ThermoPride. Can't have the best for the least and the public wants the least $$.
Uh, ya, sure thing, skippy.

XL14i substandard heat output - xl15i much higher ?
If the XL14i is great, why is the heat output so low in airdirectory database versus xl15i of same series, almost 5K btu difference in output.

One of the members pointed this out to me, really freaked me out because I can't figure out what would explain the huge difference between the 2 units of same series, or are these measurements flawed because they all use different furnace/coil combos.
Are these measurements considered to be accurate and valid?
I am about to install a xl14i hp in northeast climate and heat efficiency is crucial as backup system is oil.
Don't know what the price diff between 14 and 15 is but I feel like changing my order at least to xl15i or worse canceling (find new contractor) - I still have a couple of days to do that. SHOULD I OPT FOR XL15i for way better heat output - will that save a hundred or 2 a year (4kbuth diff)
I pretty much ignored the high temp heat outputs (47*). The low temp heat output is what I focus on. That will drive how cold you can run your HP before aux heat.
That said, same indoor coil, same furnace, the difference is 4K BTU at low heat (about 20% more heat).
I didn't shop the Trane's much, so I don't know what the other differences area between the 14 and 15.
look for the B in the middle of the model #4twx4036 "B" 1000a the website is dated.
