I'm concerned... What will happen if the discharge line is too small?
I'm checking up on my installer. I've seen a few flags. My equipment was dropped off: 3 ton Am. Standard 16 SEER R-410a, variable air handler, 3/4" suction line and 5/16th's" discharge line (two 50' rolls of each).
The run will be a little over 70 feet, condenser elevation slightly below air handler with lines going up and back down from attic, only one 90 will have to be used per line.
Do you think they just grabbed 5/16 instead of 3/8???
Should I insist on running 3/8???
I need help before tomorrow.
Thanks in advance!
