My answer was sarcastic, but you missed it. Let me be clearer:
We call the whole lot ICP because everyone knows it’s all the same. Who the hell doesn’t know that all ICP products are identical or basically identical.
Who would even ask that question? Knowing anything about hvac manufacturing?
You still didn't answer my question, what "line do you sell" and "why".
Apparently you're missing my whole line of thinking, as the more important question to those two questions is "why".
Why you buy what line of ICP you buy in a lot of aspects is no different why homeowners, who aren't in the "HVAC industry" have notions as to what they want to buy for their own home and why.
There are homeowners that refuse a brand name no matter what? If it's a bad experience, I can understand that, the bigger question becomes if that bad experience was due to the actual equipment or the HVAC installer.
Go to a HVAC supply house and ask any contractor who makes Air Quest or Arcoaire. I'm guessing at least 70% won't be able to tell you, and those are "professionals", not homeowners.
Since you're a professional in HVAC, who makes Sure Comfort? No different than ICP IMO with all their various lines.
However, if you sell and work with a line over the years, you tend to see the variances. If you're a contractor who doesn't work with that line, chances are you have no clue.
Unlike yourself, I see ICP as nothing more than Carrier, because Carrier created their own monster when they bought out ICP back around 1999.
Since your familiar with ICP, perhaps you can answer me this, as it seems I can't get a straight answer....
1 - Exactly what is the difference between the "R" series 14 SEER ICP and "N" series 14 SEER ICP unit? The only thing I can figure out is the coil coating.
2 - Why did ICP remove the high pressure switch from the "N" series as the letter than went out from ICP stated was it was not needed with redundant safeties in place on the "N" series, however, you'll find the high pressure switch on the Mainline series?
