407 2 ton question
72 low 46 temp .5 SH. 253 high 97 temp 11.4 SC ODDB 95.5
supply 61 return 77 wb 66 RH 51%
Is that operating like it should for those temps? It took apartment 1 hr 15min to cool 80 down to 76. SH was .5- 2 whole time i was charging. Charged according to specs on panel. How much affect will having improper sized suction line. This unit wants 3/4 i only have 5/8.
What do you think it is?

Something is amiss with the numbers you posted. A 97* condenser with 11.4* subcooling gives you an 85.6* liquid line. You cannot have a liquid line that is colder than the outdoor temperature (95.5) without a restriction causing a pressure/temperature drop. Other causes could be the liquid line being cooled by water dripping on it or still wet from a recent cleaning.
