I have a York Stellar Plus forced air gas furnace (High Efficiency) manufactured before 1993 that is leaking water in back side onto the sub floor. Condensate lines all are clear but have moisture in under the combustion chamber and under the AC exchanger. I cut the pvc condensate line at low point and let it drain onto garage floor and no longer have new moisture in adjacent room. Do I have a repairable problem or a get new furnace problem?
