Split system

I need to know rather the refrigerant  lines can come out or the evap and go up 6 inches then drop to the condenser?  Bob

Bob, the line out of the condenser is the liquid line and should always be filled with condensed freon under compressor discharge side pressure. (Actually you should have the accumulator in that line as well.) So it should be oblivious to routing, although it is a good idea to do it in a way that lets the line continue to give off heat until it reaches the expansion valve.

Isn't the compressor between the evaporator and the condenser? The line OUT of the evaporator then would be a suction line?

[Jim Blackwood]

Right, sorry. The suction line, somehow I missed that. So starting over, the suction line is always vapor, all the way through and doesn't care at all how you route it. It should be insulated along the entire length to improve system efficiency unless some portion of it is within the passenger compartment. However if that section is not insulated it may cause condensation under humid conditions.

Freon lines can be routed anyway. The freon under pressure or vacuum doesn't know the difference.

I'm taking it all in. And thanks  good advice !!!

....though it hardly ever is under vacuum. Almost never...
