Heat Pump only raising air temp 10-12 deg- Filter Drier?

I have a York 10 SEER heat pump from 2005. Earlier in the spring, I had the evaporator coil replaced under the home warranty that came with the house. Before that, the coil would freeze over when the AC ran. Since then, I the coil doesn't seem to freeze, but now that the heat pump is on, it doesn't seem like the temperature is rising enough (10-12 deg measured at air handler)- probably had the same issue, but not as noticeable, with the AC. I'm going to call for service, but I'm trying to think what it could be. There's always the possibility of a leak, but I noticed the filter drier was not replaced. Could this cause the problem I'm seeing? Any other thoughts?

Could be anything... From the refrigerant charge to blower speed being to high.. Need more info than just saying the filter dryer wasn't changed.

BTW, do you know how the system was recharged after the evap coil was changed? Do you know if the coil uses a piston or TXV? What was the superheat/subcooling when it was recharged?
