Carrier Coil Question
I am replacing my current system with a dual fuel Carrier system. My home was checked/sized by 3 difference companies and all indicated approximately the same size units. I have priced several different companies and types of systems and am thinking about purchasing the following Carrier system:
Heat Pump: #25HNA948
Indoor Coil: #CNPVP4821ATA
Infinity Air Purifier
My question concerns the indoor coil. The Carrier representative included the CNPVP4821ATA, which is an 'N' design. Most of what I read here on the board indicates the 'A' coil (CAP4821A) design would be better. So, should I get the 'N' coil or "A' coil for this system?
The representative said that the only difference was the 'N' coil was shorter than the 'A' coil. This was built so that the units overall height was lower and would fit more homes.
I checked the ARI Certified Performance for this system with both coils and they are the same.
