Can someone explain to me what the results of oversizing a liquid line on a straight cool unit might be? I have a 2 ton S/C RUUD system 10 SEER running 3/8 & 3/4, manuf. says should be 1/4 & 3/4 . Currently running low suction and high head for a 80F day (58psi & 270psi). Wondering if oversized liquid line could be part of the problem.
