System has a low superheat. Is also slightly overcharged. I pulled a little freon out of it and went through the system and all variables. The only thing that could be causing this issue is that the furnace isn’t blowing enough air across the coil, I think the furnace isn’t big enough even though that on paper it is the correct size. 100k btu furnace pushing across a MASSIVE 5 ton slab coil, everything is great with the system except the superheat. Adjusted pressures to bring up superheat.
