Cycled and inspected equipment. Found system not cooling during the heat of the day due to head pressure too high caused by salt deposits in condenser coil. I informed customer we could clean condenser coil but will most likely have to replace to resolve problem. Customer declined cleaning and requested quote to replace. Scheduled free estimate tomorrow 11-1 p.m. left system in same condition. Recommend: new equipment due to cost of repair, age, and overall condition of equipment.
