Hi Brian! I would not try to repair a 14 year old AC. It is typically more cost effective to replace the system, and you may not even be able to get parts depending on what went wrong. R410A units have been phased out as of last year because of EPA guidelines so nobody is making parts for those systems.
Since everything moved to the R32 refrigerant complete replacement will be required. If you want to stick with Coleman-Mach, and have a ducted system, the Coleman-Mach Signature Mach 15 # CM32RR or # CM92RR you looked at will work as a replacement. If you want something a little more cost effective the Advent Air # ADV92SR is also a good system that works with ducted and ductless. All of these come with everything you need for installation.
