Carrier - 58MVC or 59MN7?
My remodel has stretched out to the point that the system I'd been quoted -- the 58MVC -- is being phased out, and the installer is suggesting the 59MN7, which seems similar except that it is a modulating burner rather than 3-stage. The newer one is also shorter by 5-6 inches, but I don't have a space constraint.
The installer will check to see whether the 58MVC is still available. It certainly meets my needs, as would the 59MN7. The price difference is trivial (couple of hundred bucks), but still would probably never be recovered.
Should I go with the older system, which has proven itself for a few years, or go with the new 59MN7 ? Which one is likely to last longer and need less maintenance or repair?
