This is related to my other thread about the tree smashing my heat pump. I'm getting quotes from HVAC folks that differ significantly in price with part #'s that are not clear to me. I've looked on the Carrier Web site and they have soothing names like Comfort and Performance series.

The quotes I'm getting are using pure model #'s that are meaningless to me. Can anyone tell me the the difference between Carrier Heat Pump Model #25HCB324 and Model #25HBB324A003? Are both FY4BNF002 and FX4CNF030T00 model #'s for Air Handlers? What is the difference?

Thank you,
