Helping a friend diagnose 410 system but I've only done one.
Suction temp 68*, 78* day, liquid pressure 230, suction pressure 115, and top of coil is 68* or so and bottom of coil is 45*. Lots of air flow. TXV installed but non adjustable. Small Rheem system. Have not looked up the size but maybe 1.5 ton. Small.
Working on steam and hot-water systems isn't rocket science....it's actually much harder.
