I recently installed a new system at my fathers house in Florida. Its working good but Im not sure if I got it at its maximum efficiency.
I installed an AEPF30361BA variable speed air handler with a GSX13O36 condenser. R410a. The air handler is an 06, but I changed out the evap for a 410a direct replacement from Goodman since the old one was r-22 only.

I have set the blower speed dip switches for 3.5 ton blower speed with minus 15% trim.

Piston size .070 (Came with condenser)

Outdoor ambient: 88f
indoor 78f
furthest supply 53f
sh 5.4
sc 9.9
press 140.3 / 363.9

any suggestions welcome.
