Default Re: Mis-matching HVAC system (replacing outside unit without touching inside)

Most of the newer units I've seen have expansion valves on the air handlers. Don't rule out replacing the air handler..the condensate pans and insulation deteriorate, and the fan motors will eventually fail. Plus, the air handlers get REALLY nasty with mold and gunk over the years. 11 years..I'd do the whole thing if you can afford it.
