Here's the deal. We have a home that has a PG9M-06 with CK5A-06 5-TON furnace / coil. We are looking to pair the coil and furnace up with a "matched" condenser.
The CK5A-06 coil shipped with pre-installed 90 piston and it seems like a Payne PA13 condenser will be a nice match.
The CK5A is a 13-Seer Coil and can use both R-22 and R-410a (when used with a Puron TXV). The coil currently has a 90 piston. Can we just use the installed 90 piston with a Payne PA13 and call it good? OR do we need to use a R-22 TXV? Any other condensers you'd recommend for this furnace/coil combo?
