No cool in Stone Mountain found evaporator coil without door and frozen over. Cannot check air flow or refrigerant levels. Found furnace to be in bad shape overall and in need of replacement. Heat exchanger is very rusty, no filter in use, flue pipe is not attached to furnace, drain line is broken off, large sections of ductwork are missing insulation and nothing is sealed properly. Due to age, condition and cost of repairs I recommend upgrading to a newer and more efficient system at this time. System is not operating at this time.
