VS blowers, tend to get real loud on under sized duct systems.
How loud, varies with how under sized.
Along with noise. An under sized duct system also tends to decrease the life span of VS blowers. if its under sized too much.
Doubt the guy you talked to mentioned this either.
Since it has a VS blower, its a 2 stage unit then.(as I recall, Carrier doesn't have a 110,000 input furnace, could be mistaken though). Hmmm.
So you can wire it to just use first stage. This will be 65% of second stage firing rate. It won't be as efficient for the year. Nor provide the comfort 2 stage is suppose to. But, it will heat.
I figured my last post would spur up some heat...
I had to "jump" into this because I have tenants without heat and I don't have $6500 to throw into an already bad investment. But I don't blame anyone else for that.
I will post the model number in a bit after work. I have a carrier manual with numbers and dimensions, as well as a carrier installation guide. It doesn't seem like gray market to me. I figured it wasn't a currently available model since it was on sale, so i didn't bother checking carrier's web page to see if they still offer the same unit.
