Hi - getting a 3.5 ton Keeprite 16 SEER unit installed this weekend (3100 sq ft house - 32 windows, 9ft ceilings, corner lot, partially finished basement) There will be a 90 degree turn in the pipe going to the ceiling, 90 degree and then 9ft from the furnace their will be a 90 degree turn and then a quick 45 degree turn before it goes 17ft to the outside wall. Probably another turn or two once it gets outside before it's actually connected to the unit. Are having so many 90 degree and 45 degree turns going to affect the efficiency of the unit - or is t really the length of the pipe from the unit to the furnace that makes all the difference? ANY advice that I can bestow on the installers on Sunday is appreciated (just in case I see them struggle).
Many thanks! Marc in Brampton
