Came out to perform prepaid AC maintenance, performed maintenance by checking motors, voltages, amperages, drain lines, delta t, float switch, delta t, attic insulation, duct work, filter, inverter, refrigerant charge, washed out the outdoor unit with water hose, etc., etc.. while performing maintenance found that it looks like client just had some can lights out in, and that the insulation has been moved back and away from them, also that the insulation is thinning across the attic. System is operating well within manufacturer specifications please see checklist for details.
