upon my arrival for a bc/install of a Comfortmaker 13 SEER 1.5 Ton Air Conditioner customer advised me that system was not keeping up with stat. I Found refrigerant level within spec. Found return temp 90 degrees and temp at return grill 78. Led me to believe there was attic infiltration. After climbing in attic I found none of the ductwork insulated then found a large gap where they had attempted to pan off return to ceiling trusses. I Shoved a piece of insulation in gap to try and help until something more permanent can be put in place. they Will need to correctly Pan off gap with sheet metal and insulate duct work properly. I Will task install and general manager concerning working up a quote for customer and scheduling. At the time of my departure system is operational. I Also noticed the condensate drain to not have proper fall.
