Repair Quotes, Model # confusion
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?
The FX4 has a higher-efficiency blower motor. Yes, both of those are air handler models. The 25HBB324 is the builder model with R410A refrigerant. The 25HCB324 is the R410A Comfort Series unit. None of those air handlers are variable speed, if that matters to you.

didn't see that 25hbb3....was the second b an r
r3 is r-22 13 seer
hcb is r-410
It`s better to be silent and thought the fool; than speak and remove all doubt.
What's the difference between the 25HCB and 25HCA (which I am actually familiar with)? Not familiar with the 25HCB--only really seen/heard of the 25HCA. Looks like the same thing from a quick glance at ratings and data...
Variable Speed Air Handler
Thanks very much for everyone's input! This helps a lot. What benefit does a Variable Speed Air Handler provide?
If the ductwork is sufficient:
