Adding AC to existing NG furnace… upgrade to full electric?

ohioandy | Posted in Green Products and Materials on

A neighbor with an older house is pricing out installation of an A-coil air conditioner to her existing gas furnace and ductwork.  Contractor is spec’ing a run-of-the mill Rheem unit.  Is it possible to upgrade to a hyperheat split unit–installed as you would the old-fashioned A-coil in the supply plenum–that includes both cooling AND heating?  Thus the house retains the existing equipment for distribution but relegates NG to backup only.

    Yes, this is an extremely vanilla set up. You can even skip the hyper heat if the house retains the furnace for the coldest days.

      Is there a hyper heat in an A frame coil? I think most Greenspeed units are not vapor injection.
