once more about oversized evaporator

Something else to beware of is oil return. There might be excessive oil in the coils due to reduced flow. Oversizing a condenser is much less likely to cause problems since the condensing refrigerant makes a good solvent.

A very interesting point. Good one. I'd imagine the evap circuiting would also need to be set up to minimise oil entrapment.

Amazing the small things we often miss in a design, or retrofit.
