well yes it make a huge differance in condensor layout.it you dont have the liquid running down all the way you will get pockets of oil and freon that will collect and pool up.that is the number one thing wrong i see with sysytems online.i made my condensor from a larger one and resoldered the tubes so i could mount mine horizontally.as you can see in my pic the freon and oil always moves down so it will collect properly in the filter and calpillary tube.if you dont you will get erractic temp reading.the temp might cool fine and then stop suddenly because so much oil and freon has collected in a pocket.that will drive you insane trying to figure it out.
