I have two proposals for a Bryant Plus 90i Variable Capacity
Furnace Model 355MAV060100F and Bryant Two-Stage Puron Air
Conditioner Model 598BNX048000 installation. Each proposal
offers a different evaporator coil. Coil one is Bryant
Furnace N Coil -Clear Coat Puron TXV Model CK5PXA048021.
Coil two is Model CC5AXC048021.
I'm still evaluating the contractors, so before I ask them
about this I was hoping to a learn a little bit myself.
Why would there be different coils proposed?
Cost? Efficiency? Sizing?
Coil one is an "N" coil while coil two is an "A" coil.
What are there differences? Advantages/Disadvantages?
Coil one is a "cased" coil while coil two is not.
Coil one has a factory installed TXV. Coil two does not.
A TXV appears to be a regular recommendation. Coil two
proposal does not say anything about a TXV. Would I expect
that no TXV would be installed with coil two? Should I
have a TXV installed?
