Core TradesQuestion 98 of 700

During a split-system AC installation, the refrigerant line set is run with several tight kinks and an excessively long distance beyond the manufacturer's limit. The MOST likely result is:

a.Improved cooling capacity
b.Lower compressor amperage
c.No effect on performance
d.Reduced capacity and possible compressor damage from restricted refrigerant flow and improper oil return

Explanation

Kinked, over-long refrigerant lines restrict flow, cause pressure drops, and impair oil return to the compressor, reducing capacity and risking compressor failure. It does not improve capacity, lower amperage, or leave performance unaffected.
