I have checked all my books and I have never had this application before but I'm tasked with installing a condenser above the evap. It's a ductless split pack and the mech room just happens to be directly above the office space.

Please tell me if I'm wrong but I think as long as I pipe my refrigerant lines vertically upward for about a foot before running down through the floor that will keep the compressor oil from settling down in the evap correct?

Thanks all,
