I have my air handler installed in my attic, my HVAC guy will be here
next week to braze and do a nitrogen check and charge & set up the
system, I am running the copper lines up in the attic to the air
handler, is there a preference on routing the lines, I have the air
handler on 2x4 on jack raising it up 3 1/2" plus the drain pan so I have
good drain pitch, I have my choice going under the air handler to get to
the lines on the air handler or come over the top and down. any preferences.
Done correctly, there should be no fittings used... proper bends and those
limitations, as well as where the TXV mounts are all considerations. Whether
you run the lineset under or over, leave enough room to be able to remove,
access, and clean/service the system....as well as being able to remove the
coil, and or blower assemblies if required for repair/replacement.
Thanks and well explained, I do have a professional tube bending
set, there will be no fittings, under or over I will still be able to
get at the unit covers with no issues, the TXV is already mounted near
the sloped insert in the air handler. the only fittings will be for the
small filter that connects to the 3/8" line
thanks for your help
