Got lots here on this job......7 10 ton and 3 15 ton ICP RTU's. Owner was told not to buy them 8 years go and had nothing but probs. had to change all the HPCO', 3 blower motors, 6 cond fan motors and numerous contactors.Repaired all the condenser coils, leaked after 18 months, no waranty. He got them for half the price of the units we sell. Some are cracked worse than these. Filters and belts changed 2 times a year. Airflow was never an issue.
